Question... (not to sound like a party pooper here,
its a very nifty script). Why arent you trapping interupts
like SIGINT (CONTROL+C)? It would really help your script...
Here's an example:
#!/bin/sh -e
<<COMMENT
error-level table:
0 Normal
1 SIGHUP
2 SIGINT
15 SIGTERM
COMMENT
trap 'graceful_exit' 1 2 15
graceful_exit() {
echo 'put cleanup routines here...'
exit 1
}
echo 'invoke control+c for example'
sleep 10
echo 'script exited normally'
# eof
