killm

#!/bin/bash
# shell script to remove all of my IPC keys
# Modified by Robert Martin to work on Mac 10.4, due to IPCS requiring sudo to list any 
# shared memory usage, even if you own it; also modified using Jim Wyllie's "kill 
# all related processes" idea
# Simplified by Shawn Ostermann in October, 2023 to remove Enhanced Regular Expressions, "grep -E", and "sed -E"
# to make it more portable (to Solaris in particular).  Also quieted down the output a little.

# Fix for SourceForge Bug #60, killm IPC cleanup fails for long account names
# Since ipcs truncates usernames to 10 characters, we need to match against a
# truncated username so we trim the username to 10 characters.
# NOTE: This may cause conflicts with long usernames with similar beginning
#       characters. We'll look for a more robust solution in the near future.
