cs - Search and/or replace text (with some intelligence)
This documentation refers to cs version 0.7.2.
cs [option] search cs [option] search -r replace cr [option] search replace OPTIONS: search A perl regular expression. if it is written in multiple parts eg search this on the command line (ie no joinded together with quotes) the parts will be joined together with \s or if --all is used a regular expression will be written containing each part in every order, if --words the parts are seperated by .*'s. replace The value to substitute for the values found by search Search: -a --all Find all parts on regardless of order on the line -W --words Similar to --all but with out the reordering -i --ignore-case Turn off case sensitive searching -w --whole Makes the match only whole words (ie wraps with (?<\W) & (?=\W)) -c --contains[=]re Only show matches if the file also matches this sub regex. This may be declared more that once and the results are ORed. -S --not-contains[=]re Ignore any files whoes contents match this regex. -m --smart Converts multi part regexes baised on what is imput eg cs ss Class is converted to cs class Class cs n func cs function func cs b subroutine cs sub subroutine Replace: -r --replace[=]string String to replace found text with Files: -p --path[=]string A colon seperated list of directories to search in, which may include globing but you must quote so the shell doesn't do the globbing itself. (Default is current directory) -l --follow-symlinks Follow symlinks to directories --no-follow-symlinks Don't follow symlinks to directories --recurse Recurse into subdirectories (Default) --no-recurse Turns off recursing into subdirectories -n --file-include[=]string Only include files mathcing the regex (Multiple) -N --int[=]string --include-type[=]string Only include files the specified type (Mulitple) see perldoc File::TypeCategories available types -x --file-exclude[=]string Don't include files mathcing the regex (Multiple) -X --ext[=]string --exclude-type[=]string Don't include files the specified type (Mulitple) see perldoc File::TypeCategories available types --file-ignore[=]string Replace the default ignore regex -d --file-ignore-add[=]string Add this regex to the list of ignored files -r --file-ignore-remove[=]string Remove this regex to the list of ignored files Output: -C --context[=]int Show int lines of context before and after a match -B --before[=]int Show int lines before a match -A --after[=]int Show int lines after a match -t --totals Show the total number of lines & files matched -f --files-only Show only the file names containg matches -L --last[=][function|class|sub] Show the last function, class or sub name found before the matched line. -q --quiet Turn off warnings about unreadable files & directories. -u --unique Show only unique matches (just the match not the whole line) --limit[=]int Only show this number of found search results Other: -E --execute[=]cmd Run this command with the found files as arguments -P --project[=]string Use the specified projects default settings -c --config[=]file Use the specified file as the config file instead of the deafult ~/.cs -v --verbose Show more detailed option --version Prints the version information --help Prints this help information --man Prints the full documentation for cs with example usage
cs command is aimed at searching large quantities of text files with the ability to easily select searching files by type (or excluding files of a certain type). Also by default
cs excludes version control directories eg .svn or .git.
cs --path lib:t query
This would search both the directories lib/ and t/ for files containing the work query.
cs --include-type=perl --smart b do_stuff
This would search only perl files (.pl, .pm and files with the first line containing perl eg #!/usr/bin/perl or #!/usr/bin/env perl) for any declaration of a subroutine who's name starts with do_stuff eg sub do_stuff_again.
cs --exclude-type=html input
Would search all non-html files (.html, .htm, .xhtml etc) for the word input
cs --after 5 text
This would show up to 5 lines of text following any links that match text
cs --files-oly text
This would show only the names of files that contain text. This can speed the search considerably as files are stopped being searched after a single match is found
cs --unique 'CONST_[A-Z0-9]'
This will search for all upper case words starting with CONST_ and show a unique list of matched words, no files or matched lines are shown.
A configuration file placed in ~/.csrc (or specified through --conf) allows allows the setting of default values. See Config::General for full details of the file format.

default section, default values for command line options can be specified.
file_types section, you can add new file types or override or change existing file types.
In the project section, you can add defaults specific to a project which can be specified on the command line as --project=proj
By default cs uses the command
less -Rx4SFX if it can run other wise it falls back just writing to
STDOUT. You can change this environment variable
Some of the --smart capabilities (ie paging output) require the
less command to be installed other wise the paging wont available.
There are no known bugs in this module.
Please report problems to Ivan Wills (firstname.lastname@example.org).
Patches are welcome.
grep -r - Recursive
grep, can be much faster but will search into version control directories and has to be used with
find to limit the searched files.
ack - This a very similar in syntax to
grep but can't do replacements which
