ExtUtils::Command - utilities to replace common UNIX commands in Makefiles etc.

SYNOPSIS

  perl -MExtUtils::Command -e cat files... > destination
  perl -MExtUtils::Command -e mv source... destination
  perl -MExtUtils::Command -e cp source... destination
  perl -MExtUtils::Command -e touch files...
  perl -MExtUtils::Command -e rm_f files...
  perl -MExtUtils::Command -e rm_rf directories...
  perl -MExtUtils::Command -e mkpath directories...
  perl -MExtUtils::Command -e eqtime source destination
  perl -MExtUtils::Command -e test_f file
  perl -MExtUtils::Command -e test_d directory
  perl -MExtUtils::Command -e chmod mode files...
  ...

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.
