Thanks for the reply, but this doesn't work:
    $ perl -e 'print `/bin/bash jobs`'
    jobs: jobs: No such file or directory

Did it work for you?  What're you running? (Debian, bash 2.05b, perl
5.8 here).

I think the syntax may be wrong anyway.  I think you need a -c to pass
a command to bash:
	$ perl -e 'print `/bin/bash -c ls`'

...works, giving me a listing of the current dir, while:
    $ perl -e 'print `/bin/bash ls`'
    ls: /bin/ls: cannot execute binary file

Finally, this:
    $ perl -e 'print `/bin/bash -c jobs`'

...but it doesn't give me any output at all.  I think that's because
it's passing the 'jobs' command to a new invocation of the shell,
which doesn't inherit the parent shell's jobs.
