Many thanks to Herr Baehr for such a useful tool!

I've thought for a long time that MacOS should have this capability built in. Besides the SMB shares that disappear on sleep (what's up with that!?), I have other applications that should exit before sleep and start again on wake. I'm glad that SleepWatcher runs shell scripts instead of AppleScripts, although I can see how others would prefer the other.

For anyone having looking for a simple script for mounting and unmounting SMB shares, here's what I use: Create $HOME/.wakeup with this:

#!/bin/sh
#
# This file should be $HOME/.sleep and $HOME/.wakeup.
# This is run by "SleepWatcher" through /etc/rc.sleep and /etc/rc.wakeup
# I've made this one file to keep things consistent.
#

# BSD echo command needs this for escape sequences.
test "$SHELLOPTS" && shopt -s xpg_echo

tel="tell application"
case $0 in
*sleep)
  echo "$tel 42Finder42 to eject 42share42" | osascript -
  ;;
*wakeup)
  echo "$tel 42Finder42 to mount volume 42smb://s/share42" | osascript -
  ;;
esac

Then run "ln .wakeup .sleep" to make them the same file. Wayne
