4 # Licensed under the terms subversion ships under or GPLv2.
6 # Useful for greping in a subversion working copy.
7 # Essentially it behaves the same way your grep command does (in fact it
8 # ultimately calls the grep command on your path) with a few exceptions.
9 # Ignores the subversion admin directories (.svn) and vi(m) backup files.
10 # Recursive is always on with or without -r.
11 # Always print filename and line numbers.
12 # Ignores binary files.
13 # If no path is given the current working directory is searched not stdin.
14 # Other than that it will take any parameter or pattern your standard grep
15 # does.
17 # This script requires GNU findutils and by default GNU grep (though that
18 # can be changed with environment variables).
20 # There are three environment variables you can set that modify the default
21 # behavior:
23 # WCGREP_GREP Controls what command is used for the grep command.
24 # If unset or null wcgrep will use the command named grep.
25 # WCGREP_GREPARGS Controls what arguments are always passed to the grep
26 # command before the arguments given on the command line.
27 # If unset or null it defaults to -HnI (always print file
28 # names, line numbers and ignore binary files). If you wish
29 # to set no default args set the variable to a space (" ").
30 # WCGREP_IGNORE Controls what files are ignored by the grep command.
31 # This is a regex that is passed to the find command with
32 # -regex so see find's man page for details. If unset or
33 # null defaults to '.*~$\|.*/\.svn\(/\|$\)', which will
34 # ignore vim backup files and subversion admin dirs.
