Just for fun playing with subsequent args ... consider giving a try to:

Code:
# for i in $(seq 1 10) ; do echo $(< /dev/urandom tr -dc '[:alnum:],@#:!?+-' | head -c10) ; done
# for i in $(seq 1 10) ; do echo $(cat /dev/urandom -- tr -dc '[:alnum:],@#:!?+-' | head -c10) ; done
# for i in $(seq 1 10) ; do echo $(cat /dev/urandom | tr -dc '[:alnum:],@#:!?+-' | head -c10) ; done
# for i in $(seq 1 10) ; do echo $(< /dev/urandom | tr -dc '[:alnum:],@#:!?+-'  | head -c10) ; done

NAME
Locale::Msgcat - Perl extension for blah blah blah SYNOPSIS
use Locale::Msgcat; $cat = new Locale::Msgcat; $rc = $cat->catopen(name, oflag); $msg = $cat->catgets(set_number, message_number, string); $rc = $cat->catclose(); DESCRIPTION
The Locale::Msgcat module allows access to the message catalog functions which are available on some systems. A new Locale::Msgcat object must first be created for each catalog which has to be open at a given time. The catopen operation opens the catalog whose name is given as argument. The oflag can be either 0 or NL_CAT_LOCALE (usually 1) which is the recommended value. The catgets message retrieves message_number for the set_number message set, and if not found returns string. The catclose function should be used when access to a catalog is not needed anymore. EXAMPLES
use Locale::Msgcat; $cat = new Locale::Msgcat; unless ($cat->catopen("whois.cat", 1)) { print STDERR "Can't open whois catalog. "; exit(1); } printf "First message, first set : %s ", $cat->catgets(1, 1, "not found"); unless ($cat->catclose()) { print STDERR "Can't close whois catalog. "; exit(1); } The above example would print the first message from the first message set found in the whois catalog, or if not found it would print "not found". AUTHOR
