I have a perl script that just does a `du -sk -x` and formats it to look groovy ( the argument can be a directory but usually is like /usr/local/* )
The script works fine and does all that i want it to and i use it all the time, however is there an internal perl function that could replace the du -sk -x? I am just curious and would like to have a pure perl script with no shell options (primarily because the du options are not standard across the UNIX/Linux world). This is on a RHEL box just FYI. An external module might work too, if i can get them to let me install it.

smrsh
SMRSH(8) System Manager's Manual SMRSH(8)NAME
smrsh - restricted shell for sendmail
SYNOPSIS
smrsh -c command
DESCRIPTION
The smrsh program is intended as a replacement for sh for use in the ``prog'' mailer in sendmail(8) configuration files. It sharply limits
the commands that can be run using the ``|program'' syntax of sendmail in order to improve the over all security of your system. Briefly,
even if a ``bad guy'' can get sendmail to run a program without going through an alias or forward file, smrsh limits the set of programs
that he or she can execute.
Briefly, smrsh limits programs to be in a single directory, by default /usr/lib/sendmail.d/bin/ allowing the system administrator to choose
the set of acceptable commands, and to the shell builtin commands ``exec'', ``exit'', and ``echo''. It also rejects any commands with the
characters ``', `<', `>', `;', `$', `(', `)', `
' (carriage return), or `
' (newline) on the command line to prevent ``end run'' attacks.
It allows ``||'' and ``&&'' to enable commands like: ``"|exec /usr/local/bin/filter || exit 75"''
Initial pathnames on programs are stripped, so forwarding to ``/usr/bin/vacation'', ``/usr/bin/vacation'', ``/home/server/mydir/bin/vaca-
tion'', and ``vacation'' all actually forward to `/usr/lib/sendmail.d/bin/vacation''.
System administrators should be conservative about populating the /usr/lib/sendmail.d/bin/ directory. For example, a reasonable additions
is vacation(1), and the like. No matter how brow-beaten you may be, never include any shell or shell-like program (such as perl(1)) in the
/usr/lib/sendmail.d/bin/ directory. Note that this does not restrict the use of shell or perl scripts in the /usr/lib/sendmail.d/bin/
directory (using the ``#!'' syntax); it simply disallows execution of arbitrary programs. Also, including mail filtering programs such as
procmail(1) is a very bad idea. procmail(1) allows users to run arbitrary programs in their procmailrc(5).
COMPILATION
Compilation should be trivial on most systems. You may need to use -DSMRSH_PATH="path" to adjust the default search path (defaults to
``/bin:/usr/bin'') and/or -DSMRSH_CMDDIR="dir" to change the default program directory (defaults to ``/usr/lib/sendmail.d/bin/'').
FILES
/usr/lib/sendmail.d/bin/ - default directory for restricted programs on SuSE Linux
