Sounds great but it's not quite *that* simple:
- if you use '' to quote, you'll need to quote the ' character -- and
in the Bourne shell the only way is with a construct such as '\'':

output: 'job name with '\'' in it'
- if instead you use "" to quote, you still have characters you have to
deal with: " ` $ \
