> psh - parallel command interpreter (shell)
I have the same requirement, but I solved it with:
parallel - run command line for each arg from stdin
parallel [-n n] command [arg] ... < arglist
This tool executes command for each element of arglist. If
command contains any spaces or I/O redirection, we pass it
to sh(1) to execute it (there should be no additional args),
otherwise we first attempt to exec(2) command directly.
I have .sh,.pl and C versions of this tool and it is used on several
platforms to run jobs (like gathering some data from 1000 routers)
For serious parallel SNMP collection I have a dedicated tool
that can collect 100's of vars from 1000's of routers in parallel,
but for most tasks simply running 8-20 instances of a standard
tool does the job.
Anyway, hacking this into sh is probably not the best solution.
