[clug] how can I know umount command do success!

[Stephen Jenkin]

Sorry for wasting bandwidth with a second message...  Bear of Little Brain
today :-(

Answering the subject line 'how can I know umount command succedded?'
Use the '&&' (and) construct - the second command will ONLY be executed if
the first command succeeds...

Try:

#/bin/sh
umount /volume1 && rm -rf /volume1
umount /volume2 && rm -rf /volume2
