DESCRIPTION

The module is used to replace common UNIX commands. In all cases the functions work from @ARGV rather than taking arguments. This makes them easier to deal with in Makefiles.

perl -MExtUtils::Command -e somecommand some files to work on

NOT

perl -MExtUtils::Command -e 'somecommand qw(some files to work on)'

For that use Shell::Command. Filenames with * and ? will be glob expanded. cat cat file ... Concatenates all files mentioned on command line to STDOUT. eqtime eqtime source destination Sets modified time of destination to that of source. rmrf rmrf files or directories ...

Removes files and directories - recursively (even if readonly)

rmf rmf file ... Removes files (even if readonly) touch touch file ... Makes files exist, with current timestamp mv mv sourcefile destinationfile mv sourcefile sourcefile destinationdir

Moves source to destination. Multiple sources are allowed if des-

tination is an existing directory. Returns true if all moves succeeded, false otherwise. cp cp sourcefile destinationfile cp sourcefile sourcefile destinationdir Copies sources to the destination. Multiple sources are allowed if destination is an existing directory. Returns true if all copies succeeded, false otherwise. chmod chmod mode files ... Sets UNIX like permissions 'mode' on all the files. e.g. 0666 mkpath mkpath directory ... Creates directories, including any parent directories. testf testf file Tests if a file exists dos2unix dos2unix files or dirs ... Converts DOS and OS/2 linefeeds to Unix style recursively.
