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
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
$ 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.
