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. Call them like this:
perl -MExtUtils::Command -e some_command some files to work on
and NOT like this:
perl -MExtUtils::Command -e 'some_command qw(some files to work on)'
For that use Shell::Command.
Filenames with * and ? will be glob expanded.
FUNCTIONS
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.
rm_rf
rm_rf files or directories ...
Removes files and directories - recursively (even if readonly)
rm_f
rm_f file ...
Removes files (even if readonly)
touch
touch file ...
Makes files exist, with current timestamp
mv
mv source_file destination_file
mv source_file source_file destination_dir
Moves source to destination. Multiple sources are allowed if destination is an existing directory.
Returns true if all moves succeeded, false otherwise.
cp
cp source_file destination_file
cp source_file source_file destination_dir
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.
test_f
test_f file
Tests if a file exists. Exits with 0 if it does, 1 if it does not (ie. shell's idea of true and false).
test_d
test_d directory
Tests if a directory exists. Exits with 0 if it does, 1 if it does not (ie. shell's idea of true and false).
dos2unix
dos2unix files or dirs ...
Converts DOS and OS/2 linefeeds to Unix style recursively.
SEE ALSO
Shell::Command which is these same functions but take arguments normally.
