Photoshop does not have a system() call but it does have a File.execute() call. The only problem on the Mac is that the shell script has to have its execute bit set and you can't set that from within PS JS. The simplest work-around is to create the script ahead of time. If you need something more dynamic,
But if you really want a system call, here's some stuff from xtools:
This shell script creates a macapp thingy. I adapted this from someone else's idea. You run it once and it sets up the macexec.app in the Presets/Scripts folder. Make sure the PS path is correct.
#!/bin/bash
#
# createMacExec.sh
#
# $Id$
#
# This is the Mac exec installation script.
# This creates the necessary files and folders needed to execute shell scripts
# under OSX.
#
# Installation instructions:
#
# To install the OSX shell script support, open a terminal window and change to
# the parent directory, possibly Presets/Scripts
#
# Run this script:
# % ./createMacExec.sh
#
# When this script runs, it creates a folder called 'macexec.app' and some
# folders and files underneath which allows Exec from xexec.js to call
# shell scripts.
#
# Example:
# alert(Exec.system("ls -l ~/"));
#
# Specify the desired parent directory here
# Exec defaults to using this path
IDIR="/Applications/Adobe Photoshop CS4/Presets/Scripts"
if [ ! -e "$IDIR" ]; then
echo Bad directory specified ${IDIR}
exit 1
fi
cd "$IDIR"
mkdir -p macexec.app
mkdir -p macexec.app/Contents
rm -f macexec.app/Contents/macexec
touch macexec.app/Contents/macexec
chmod 755 macexec.app/Contents/macexec
# this is a hook for later so that shell variables (e.g. PATH)
# can be autoloaded from macexec
cat > macexec.app/Contents/macexec.env << EOF
#!/bin/bash
EOF
echo macexec successfully installed
# EOT
xtools/xlib/xexec.jsx contains the Exec.system call which handles the details writing the command to the right file, executing the sciprt, and collecting and returning the results.

Why would it NOT be documented? Anyone tested what other suite apps it works with? It would be nice to know… Thought Paul might have had a magic pixie install with merlin and mushrooms…
