# ----------
# PURPOSE: 
# Bash script called from pre-command trigger, firing when 'p4 add/edit/reopen' is run.
# This checks the arguments passed to the command ('argsQuoted' trigger script variable), checking for the flag that allows a type change ('-t'). 
# If found, the command is rejected with a sensible warning message. 
# 
# Example trigger entry:
# notypechange command pre-user-(add|edit|reopen) "%//scripts/triggers/noTypeChange.sh% %user% %client% %serverid% %command% %argsQuoted%"
#
# ----------
# Next steps:
# - enhance the trigger - more control/error-handling/logging?
# - find a use for (or simply remove) 'user', 'client', 'server'; at present, only command and argsQuoted are used.

user=$1
client=$2
server=$3
cmd=$4
argsQuoted=$5

if [ $out = 0 ]; then
