Allows you to invoke Unix shell utilities as if they were Perl subroutines. Arguments (including switches) are passed to the utilities as strings:
use Shell qw(date cp ps); # List shell commands you want to use
$date = date( ); # Put the output of the date(1) command into $date
cp("-p" "/etc/passwd", "/tmp/passwd"); # Copy password file to a tmp file
print ps("-ww"); # Print the results of a "ps -ww" command |  | |
