.SH "NAME"
ExtUtils::Command \- utilities to replace common UNIX commands in Makefiles etc.
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 11
\&  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...

.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The module is used to replace common \s-1UNIX\s0 commands.  In all cases the
functions work from \f(CW@ARGV\fR rather than taking arguments.  This makes
them easier to deal with in Makefiles.
.PP
.Vb 1
\&  perl -MExtUtils::Command -e some_command some files to work on
.Ve
.PP
\&\fI\s-1NOT\s0\fR
.PP
.Vb 1
\&  perl -MExtUtils::Command -e 'some_command qw(some files to work on)'
.Ve
.PP
For that use Shell::Command.
.PP
Filenames with * and ? will be glob expanded.
.IP "cat" 4
.IX Item "cat"
.Vb 1
\&    cat file ...
.Ve
.Sp
Concatenates all files mentioned on command line to \s-1STDOUT\s0.
.IP "eqtime" 4
.IX Item "eqtime"
.Vb 1
\&    eqtime source destination
.Ve
.Sp
Sets modified time of destination to that of source.
.IP "rm_rf" 4
.IX Item "rm_rf"
.Vb 1
\&    rm_rf files or directories ...
.Ve
.Sp
Removes files and directories \- recursively (even if readonly)
.IP "rm_f" 4
.IX Item "rm_f"
.Vb 1
\&    rm_f file ...
.Ve
.Sp
Removes files (even if readonly)
.IP "touch" 4
.IX Item "touch"
.Vb 1
\&    touch file ...
.Ve
.Sp
Makes files exist, with current timestamp
.IP "mv" 4
.IX Item "mv"
.Vb 2
\&    mv source_file destination_file
\&    mv source_file source_file destination_dir
.Ve
.Sp
Moves source to destination.  Multiple sources are allowed if
destination is an existing directory.
.Sp
Returns true if all moves succeeded, false otherwise.
.IP "cp" 4
.IX Item "cp"
.Vb 2
\&    cp source_file destination_file
\&    cp source_file source_file destination_dir
.Ve
.Sp
Copies sources to the destination.  Multiple sources are allowed if
destination is an existing directory.
.Sp
Returns true if all copies succeeded, false otherwise.
.IP "chmod" 4
.IX Item "chmod"
.Vb 1
\&    chmod mode files ...
.Ve
.Sp
Sets \s-1UNIX\s0 like permissions 'mode' on all the files.  e.g. 0666
.IP "mkpath" 4
.IX Item "mkpath"
.Vb 1
\&    mkpath directory ...
.Ve
.Sp
Creates directories, including any parent directories.
.IP "test_f" 4
.IX Item "test_f"
.Vb 1
\&    test_f file
.Ve
.Sp
Tests if a file exists
.IP "dos2unix" 4
.IX Item "dos2unix"
