Your shell variables should appear in double quotes outside of single quotes. In this simple case you can do
More complex perl code should be in single quotes, but ending around the shell variables as follows:
The shell sees 3 strings and does variable substitution in the middle string because it is in double quotes.

This won't work if the file names have space characters, or can result in 'too many arguments' if there are many files.

Perfect. In spaces in my file names, but the occasional hyphen (I know, I should *never* use hyphens, but...)
Thanks very much for the clear and thorough response.
I am playing around with Perl and wrote the script below that is executed from the command line, it will split data up in a file based on a value supplied.

SYSLOGOUT(8) System Manager's Manual SYSLOGOUT(8)NAME
syslogout - modular centralized shell logout mechanism
DESCRIPTION
syslogout is a generic approach to enable centralized shell logout actions for all users of a given system in a modular and centralized way
mostly aimed at avoiding work for lazy sysadmins. It has only been tested to work with the bash shell.
It basically consists of the small /etc/syslogout shell script which invokes other small shell scripts having a .bash suffix which are con-
tained in the /etc/syslogout.d/ directory. The system administrator can drop in any script he wants without any naming convention other
than that the scripts need to have a .bash suffix to enable automagic sourcing by the /etc/syslogout script.
For shell sessions, the contents of /etc/syslogout.d/" will be sourced by every user at logout if the following lines are present in his
$HOME/.bash_logout:
if [ -f /etc/syslogout ]; then
. /etc/syslogout
fi
If used for X sessions it is advisable to include the former statement into the Xreset script of the X display manager instead to prevent
that closing of an terminal emulator window yields unexpected results in your running X session if your X11 terminal emulator is using a
login shell. Be sure then to run it under the user-id of the X session's user. See the example files in /usr/share/doc/syslogout/ for
illustration.
Users not wanting /etc/syslogout to be sourced for their environment can easily disable it's automatic mechanism. It can be disabled by
simply creating an empty file called $HOME/.nosyslogout in the user's home directory using e.g. the touch(1) command.
Any single configuration file in /etc/syslogout.d/ can simply be overridden by any user by creating a private $HOME/.syslogout.d/ directory
which may contain a user's own version of any configuration file to be sourced instead of the system default. It's names have just to
match exactly the system's default /etc/syslogout.d/ configuration files. Empty versions of these files contained in the $HOME/.syslo-
gout.d/ directory automatically disable sourcing of the system wide version.
Naturally, users can add and include their own private scripts to be automagically executed by /etc/syslogout at logout time.
OPTIONS
There are no options other than those dictated by shell conventions. Anything is defined within the configuration scripts themselves.
SEE ALSO
The README files and configuration examples contained in /usr/share/doc/syslogout/ and the manual page for bash(1), xdm(1x),
xdm.options(5), and wdm(1x). Recommended further reading is everything related with shell programming.
If you need a similar mechanism for executing code at login time check out the related package sysprofile(8) which is a very close compan-
ion to syslogout.
BUGS
syslogout in its current form is mainly restricted to bash(1) syntax. In fact it is actually a rather embarrassing quick and dirty hack
than anything else - but it works. It serves the practical need to enable a centralized bash configuration until something better
becomes available. Your constructive criticism in making this into something better" is very welcome. Before i forget to mention it: we
take patches... ;-)
