Update some of control file's fields, eg. Version (increase by 1 if there is any file in the package newer than control file), Installed-Size...

In multiarch mode, instead of ./deb folder, it takes data from all folders in the current working directory which name is a valid Debian architecture name (eg. amd64, i386, ...), and stores temporary files in ./deb for building each architecture's package.

Mkdeb also considers mkdeb-perms.txt file in the current working directory to set some file attributes in the package, otherwise all file attributes are gonna be the same as on the original. Each line in this file looks like:

<MODE> <OWNER> <GROUP> <PATH>

Where

<MODE>

is an octal file permission mode, 3 or 4 digits, or "-" to ignore

<OWNER>

UID or name of the owner user

<GROUP>

NAME

parsel - Select parts of a HTML document based on CSS selectors

INVOCATION

cat page.html | parsel <SELECTOR> [<SELECTOR> [...]]

DESCRIPTION

This command takes an HTML document in STDIN and some CSS selectors in arguments. See 'parsel' and 'cssselect' python modules to see which selectors and pseudo selectors are supported.

Each SELECTOR selects a part in the DOM, but unlike CSS, does not narrow the DOM tree considered by subsequent selectors. So a sequence of div p arguments (2 arguments) selects all <DIV> and then all <P> in the document; in other words it is NOT equivalent to the div p css selector which selects only those <P> which are under any <DIV>.

Each SELECTOR also outputs what was matched, in the following format: First output an integer how many distinct HTML parts were selected, then output the selected parts themself each in its own line. CR, LF, and Backslash chars are escaped by one Backslash char. It's useful for programmatic consumption, because you only have to fist read a line which tells how many subsequent lines to read: each one is a DOM part on its own. Then just unescape Backslash-R, Backslash-N, and double Backslashes to get the HTML content.

Additionally it takes these special arguments as well:

@SELECTOR

Prefix your selector with an @ at sign to suppress output. Mnemonic: Command line echo suppression in DOS batch and in Makefile.

text{} or ::text

Remove HTML tags and leaves text content only before output. text{} syntax is borrowed from pup(1). ::text form is there for you if curly brackets are magical in your shell and you don't bother escaping. Note, ::text is not a valid CSS pseudo selector at the moment.

attr{ATTRIB} or [[ATTRIB]]

Output only the value of the uppermost selected element's ATTRIB attribute. attr{} syntax is borrowed from pup(1). Mnemonic for the [[ATTRIB]] form: in CSS you filter by tag attribute with [attr] square brackets, but as it's a valid selector, parsel(1) takes double square brackets to actually output the attribute.

/ (forward slash)

A stand-alone / takes the current selection as a base for the rest of the selectors. Mnemonic: one directory level deeper. So this arg sequence: .content / p div selects only those P and DIV elements which are inside a "content" class. This is useful because with css only, you can not group P and DIV together here. In other words neither .content p, div nor .content > p, div provides the same result.

.. (double period)

A stand-alone .. rewinds the base DOM selection to the previous base selection before the last /. Mnemonic: parent directory.

@:root

Rewind base selection back to the DOM's root. Note, :root is also a valid CSS pseudo selector, but in a subtree (entered into by /) it would yield only that subtree, not the original DOM, so parsel(1) goes back to it at this point. You likely need @ too to suppress output the whole document here.

EXAMPLE OUTPUT

  $ parsel input[type=text] < page.html
  2
  <input type="text" name="domain" />
  <input type="text" name="username" />

  $ parsel input[type=text] [[name]] < page.html

NAME

partial - Show an earlier started long-running command's partial output

SYNOPSIS

partial [--restart|--forget|--wait|--pid] <COMMAND> [<ARGUMENTS>]

DESCRIPTION

On first invocation partial(1) starts COMMAND in the background. On subsequent invocations, it prints the command's output to stdout which is generated so far, including the parts which are shown before too, and keep it running in the background. Hence the name 'partial', because it shows a command's partial output. When the command finished, partial(1) prints the whole output and exits with COMMAND's exit code.

OPTIONS

-f, --forget

Terminate (SIGTERM) previous instance of the same command and clean up status directory, even if it's running.

-r, --restart

Terminate command if running (like with --forget) and start it again.

-w, --wait

On first run, wait for the complete output.

-p, --pid

display PID

-q, --quiet

less verbose

STATUS CODES

1. command started

2. partial output shown

   nnn

   called command returned with this status code nnn

LIMITS

If COMMAND does not exit normally, but gets terminated by a signal, the exit code is indistinguishable from a normal exit's status code, due to bash(1) uses the value of 128+N as the exit status when a command terminates on a fatal signal N.

pvalve - Control how much a given command should run by an other command's exit code

SYNOPSIS

pvalve [<CONTROL COMMAND>] -- [<LONG RUNNING COMMAND>]

Controls when LONG RUNNING COMMAND should run, by pause and unpause it according to the CONTROL COMMAND's exit status.

DESCRIPTION

Pause LONG RUNNING COMMAND process group with STOP signal(7) if CONTROL COMMAND exits non-zero. Unpause LONG RUNNING COMMAND process group with CONT signal(7) if CONTROL COMMAND exits zero.

Pvalve takes the last line from CONTROL COMMAND's stdout, and if looks like a time interval (ie. positive number with optional fraction followed by optional "s", "m", or "h" suffix) then the next checking of CONTROL COMMAND will start after that much time. Otherwise it takes PVALVE_INTERVAL environment variable, or start next check immediately if it's not set.

Pvalve won't bombard LONG RUNNING COMMAND with more consecutive STOP or CONT signals.

USEFULNESS

It's useful eg. for basic load control. Start a CPU-intensive program in LONG RUNNING COMMAND and check hardware temperature in CONTROL COMMAND. Make it exit 0 when temperature is below a certain value, and exit 1 if above an other, higher value.

ENVIRONMENT

PVALVE_INTERVAL

Default interval between two CONTROL COMMAND runs.

PVALVE_STATUS

PVALVE_STATUS describes whether LONG RUNNING COMMAND should be in running or in paused state. Possible values: RUN, STOP. This environment is available by CONTROL COMMAND.

CAVEATS

Further process groups which are created by LONG RUNNING COMMAND will not be affected.

takeown - Take ownership on files, even for unprivileged users

SYNOPSIS

takeown [options] <files and directories>

DESCRIPTION

Command chown(1) or chown(2) is permitted only for root (and processes with CAP_CHOWN), but normal users can imitate this behavior. You can copy other users' file to your own in a directory writable by you, and then replace the original file with your copy. It is quite tricky and maybe expensive (copying huge files), but gives you an option. Say, when somebody forgot to use the right user account when saving files directly to your folders.

takeown(1) uses *.takeown and *.tookown filename extensions to create new files and to rename existing files to respectively.

See takeown --help for option list.

subst_sudo_user - Sudo helper program

SYNOPSIS

subst_sudo_user <COMMAND> [<ARGUMENTS>]

Substitute literal $SUDO_USER in the ARGUMENTS and run COMMAND.

RATIONALE

It enables sys admins to define sudoers(5) rule in which each user is allowed to call a privileged command with thier own username in parameters. Example:

  %users ALL=(root:root) NOPASSWD: /usr/tool/subst_sudo_user passwd $SUDO_USER

This rule allows users to run subst_sudo_user (and subsequentially passwd(1)) as root with verbatim $SUDO_USER parameter. So no shell variable resolution happens so far. Subst_sudo_user in turn, running as root, replaces $SUDO_USER to the value of SUDO_USER environment variable, which is, by sudo(1), guaranteed to be the caller username. Then it runs passwd(1) (still as root) to change the given user's password. So effectively with this rule, each user can change their password without knowing the current one first (because passwd(1) usually does not ask root for his password).

EXAMPLES

  %USERS ALL=(root:root) NOPASSWD: /usr/tool/subst_sudo_user /usr/bin/install -o $SUDO_USER -m 0750 -d /var/backup/user/$SUDO_USER

filterexec - Echo those arguments with which the given command returns zero.

SYNOPSIS

filterexec <COMMAND> [<ARGS>] -- <DATA-1> [<DATA-2> [... <DATA-n>]]

DESCRIPTION

Prints each DATA (1 per line) only if command "COMMAND ARGS DATA" exits succesfully, ie. with zero exit status.

EXAMPLE

  filterexec test -d -- $(ls)

Shows only the directories.

NAME

trackrun - Record when the given command was started and ended and expose to it in environment variables

SYNOPSIS

trackrun [<OPTIONS>] [--] <COMMAND> [<ARGS>]

OPTIONS

-f, --full-command

-b, --command-basename (default)

-n, --name NAME

-e, --env-var ENV

DESCRIPTION

It records when it starts COMMAND and when it ends, identifying COMMAND either by one of 4 options: (1) Full command line including ARGS. (2) Only the command name, COMMAND. (3) By the name given by the user in NAME. (4) By the environment variable given by name ENV.

Set TRACKRUN_LAST_STARTED and TRACKRUN_LAST_ENDED environments for COMMAND to the ISO 8601 representation of the date and time when COMMAND was last started and ended respectively. Set TRACKRUN_LAST_STATUS to the status COMMAND last exited with. Those are left empty if no data yet.

FILES

Store tracking data in ~/.trackrun directory.

ENVIRONMENT

TRACKRUN_LAST_STARTED

TRACKRUN_LAST_ENDED

TRACKRUN_LAST_STATUS

LIMITATIONS

Trackrun does not do locking. You may take care of it if you need using flock(1), cronrun(1), or similar.

NAME

oded - On-disk editor - edit text files by commands directly from shell

SYNOPSIS

 oded [<OPTIONS>] <INSTRUCTIONS>

DESCRIPTION

Edit files by issuing editor commands like shell commands, but with the paradigm of well-known visual text processors: open file, move cursor, type in text, search and replace, select, copy, paste, ...

May open multiple files. Always one file is in the foreground. All opened files has a cursor position at which most commands are applied.

Files also have several marks which you can set or refer to in select or goto commands. A special pair of marks is SELECTION-START and SELECTION-END which pins the currently selected text for you.

You have one clipboard.

Oded first executes INSTRUCTIONS given in parameters, then all the instructions given at --script option(s), if any.

OPTIONS

-f, --script FILE

Take instructions from FILE when done processing instructions given in parameters. May specify multiple times. Exit immediately on unknown command or parse error or if a command fails.

--stdin

Take instructions from STDIN line-by-line. Contrary to --script scripts, it does not exit on errors, just shows what was the exception, and continues reading instructions. Suitable for interactive mode. Same as --script -, except in error handling.

-v, --verbose

-b, --successful-prompt-command INSTRUCTIONS

Set what INSTRUCTIONS to run after each successful command in interactive mode (ie. --stdin).

INSTRUCTIONS

open [file] PATH [as NAME]

open or create [file] PATH [as NAME]

open new [file] PATH [as NAME]

Open PATH file to edit. open file PATH only opens already existing files, open or create ... creates the file if it is not yet there. open new file ... opens a file only if it does not exist yet.

You can switch between multiple opened files by invoking open PATH or open file PATH again, or open NAME if you opened the file under a certain NAME by as NAME.

Don't worry, it won't open the same PATH multiple time with conflicting editor states. However your system may allow accessing the same file (by soft and hard links) on different paths. Oded considers only the PATH string when discerning files, so x.txt and ./x.txt and .//x.txt are handled separatedly. You have to open a file before any operation.

open [NAME | PATH]

Switch to an already opened file with the given NAME alias or PATH path, if NAME alias is not found. You can not open a file on path PATH once you set NAME as an alias for a file on an other PATH. But you can always refer to the same path by prepending ./ (or / in case of absolute paths) to it.

goto end of [last] search result

goto [start | end] [of file]

goto [start | end] of line

goto [sof | eof | sol | eol]

goto [previous | next] line

goto [line | offset] NUMBER

Lines and byte offsets are indexed by 0.

goto mark NAME

Set cursor position in file.

go [back | forward] COUNT line[s]

[go] [up | down | left | right] [COUNT times]

type STRING

enter [STRING]

Insert given STRING into the current cursor position. It does not overwrite current selection. Add newline to the end only if called as c<enter>.

overwrite with STRING

overtype with STRING

Type given STRING into the current cursor position in overwrite mode. It does not overwrite current selection, but the text itself let it be currently selected or not.

replace all [[occurrences of] PATTERN] to STRING

replace all [occurrences | PATTERN] to STRING

replace [next [COUNT]] [[occurrence[s] of] PATTERN] to STRING

replace [next [COUNT]] [occurrence[s] | PATTERN] to STRING

Replace given PATTERN to STRING. If PATTERN is not given, then the last search pattern will be used. "Replace next" changes only the next COUNT number of occurrences starting from the cursor position. Default is 1 occurrence, if COUNT is not given. "Replace all" changes all the occurrences from the cursor position down to the end of file. If you want to replace all the occurrences in the whole file, "goto start" first.

delete [COUNT char[s]]

backspace [COUNT char[s]]

search [next] PATTERN [backward]

Find next occurrence (or previous one if "backward" is specified) of PATTERN and set the cursor to it. PATTERN is either a bare word, a string enclosed in quotes, or a regexp enclosed in slashes (/regexp/). PATTERN is not supported to overhang from one line to the next. Remove newlines from the text if you must. If the cursor is at a matching text, search PATTERN will find the very place where we are, while search next ... skips 1 char and continues from there.

search next [//]

Continue searching the next occurrence of the last search query. You may close this instruction with an empty pattern (//) to separate it from the next instruction, since the empty search PATTERN (both fixed text and regexp) is invalid, thus not searching an other pattern but the last one. In interactive mode search next is enough.

mark as NAME

Put a named mark to the current cursor position. NAME must not be a reserved mark name: START, END, SOL, EOL, HERE.

clear mark NAME

select from START-MARK to END-MARK

Select text from the previously named mark START-MARK to END-MARK. Put marks with mark as command. You have some special predefined marks:

START beginning of the file

END end of the file

HERE current cursor position

SOL start of line

EOL end of line, excluding the line ending (Newline) char

select [from | to] MARK

If either from or to is missing, HERE is implied.

select [last] search result

select none

select [COUNT] [char[s] | word[s] | line[s]]

copy [[selection] | [last] search result | to [start | end] of line]

cut [[selection] | [last] search result | to [start | end] of line]

delete [selection | [last] search result | to [start | end] of line]

[copy | cut] [selection]

delete selection

[copy | cut | delete] [last] search result

[copy | cut | delete] to [the] [start | end] of line

paste [selection]

undo

redo

insert file FILE

insert output of COMMAND

Insert FILE's contents or the output (stdout) of COMMAND to the current cursor position.

filter selection through COMMAND

NAME

cled - Command Line-Editor - Edit text file lines by commands directly from shell

SYNOPSIS

 cled [<OPTIONS>] <EXPR> [<EXPR> [...]] [-- <FILE> [<FILE> [...]]]

DESCRIPTION

Each EXPR expression consist of an optional SELECTOR term and a command and variable number of arguments depending on the command (see COMMANDS section), like:

 <SELECTOR>[..<SELECTOR>] <COMMAD> [<ARG> [<ARG> [...]]]

You may narrow the COMMAND's effect by a SELECTOR term. A SELECTOR selects either one line or a closed range of lines. For ranges, put .. (double dot) between SELECTORs. A SELECTOR may be a regexp, ie. /PATTERN/[MODIFIERS], or a line number, or the literal word last which means the last line. SELECTOR syntax:

 [ /<REGEXP>/[<MODIFIERS>][[+ | -]<OFFSET>] | <LINE> | last[-<OFFSET>] ]

Examples:

 10../lorem/i

Select line 10 and all subsequent lines down to the first one matching to case-insensitive "lorem".

 /begin/../end/

Select the lines between /begin/ and /end/ inclusively.

 /begin/+1../end/-1

Select the lines between /begin/ and /end/ exclusively.

The 2nd SELECTOR does not get tested on the same line as the 1st SELECTOR. So you can select at least a 2-lines long range by eg. /start/../stop/. If the 2nd SELECTOR is REGEXP and it does not match any lines, then practically it's an open-ended range, so the rest of the file is selected. Line numbers are indexed from 0.

REGEXP and the last SELECTOR have an optional OFFSET: eg. /begin/+2 selects the 2nd line following a line matching to /begin/. The last SELECTOR obviously supports only negative OFFSETs.

An EXPR expression can be a group denoted by brackets, in which there are subexpressions like EXPR. This way you can do multiple COMMAND commands, all when the common SELECTOR matches to the line in order:

 /^d/ [ ltrim prepend " " ]

Which removes all leading whitespace, if any, from lines starting with "d" and inserts a single space at the beginning of all of them. See COMMANDS below for all the supported editor commands.

Currently 3 type of brackets are supported: [ ... ] square, { ... } curly, and ( ... ) parenthesis. Use the square one to save shell escaping.

OPTIONS

-f, --file PATH

File to edit. May specify multiple times. Files are edited in-place by default, by persisting their Inode, ie. buffer the output data and write to the original input file when it's all read up. If --output option(s) is (are) given, then the file(s) won't be modified in-place, rather than saved in output file(s). If not given any --file, works on STDIN and print to STDOUT.

-o, --output PATH

File to save modified data into. May specify multiple times. If less --output parameters given than --file, then the input files without a corresponding output file will be edited in-place.

-c, --confirm

Prompt for confirmation for each selected line. If a readline module is installed then you may do further changes to the lines interactively. Term::ReadLine::Gnu(3pm) module is recommended.

Press Ctrl-J to insert newline (LF) at the cursor position, as it's not added automaticaly to the end of line.

If no readline module available, press only a single Enter to accept changes, and Ctrl-C to revert to the original line, or type in new content and press Enter to replace the promped line (newline is added to the end in this case). Additionally an inverse space char at the end of line indicates if the last line is not terminated by a newline.

-v, --verbose

Print edited lines to STDERR. Prefixed with line number if option -l is given. A line is edited if it's selected by any SELECTOR and not reverted thereafter at the interactive prompt.

-l

Show line numbers in verbose mode.

COMMANDS

s/<PATTERN>/<REPLACEMENT>/[<MODIFIERS>]

Regexp substitution. Works just like in perl(1). See perlre(1).

edit

Edit selected lines interactively by a readline interface. See --confirm option in OPTIONS section for details.

delete

Delete matching line(s).

ltrim, rtrim, trim

Remove leading (ltrim), trailing (rtrim), or leading and trailing (trim) whitespace from the line. End-of-line char (LF, \ ) is preserved.

replace STR1 STR2

Replace all STR1 to STR2.

replaceword STR1 STR2

Replace whole word STR1 to STR2.

replaceline STR

Replace the whole line to STR.

prepend STR

Prepend STR to the line.

insertline STR

Insert STR as a whole line before the matching line(s). Line numbering is preserved as there was not an inserted line, ie. line numbers are not incremented.

insertfile PATH

Insert the content of PATH file before the matching line(s). The last line of PATH file will be separated from the matched line by a newline (LF) either way. Line numbering is preserved as described above.

append STR

Append STR to the line.

appendline STR

Append STR as a whole line to the matching line(s). Line numbering is preserved as described above.

If COMMAND returned with code FROM then rcmod(1) returns with TO. FROM may be a comma-delimited list. Keyword any means any return code not specified in FROM parameters. Keyword same makes the listed exit codes to be preserved.

  rcmod any=0 1=13 2,3=same user-command

It runs user-command, then exits with status 13 if user-command exited with 1, 2 if 2, 3 if 3, and 0 for any other return value.

If COMMAND was terminated by a signal, rcmod(1) exits with 128 + signal number like bash(1) does.
