Re: Calling a perl script from GNU Parallel

I'm not a parallel user but here's some suggestions for things to check (a few are very basic but I don't know what you've tried):

Is ./test.pl executable?
Does ./test.pl have a shebang line that is incompatible with your target servers?
Is ./test.pl trying to read from stdin?
Does ./test.pl run without errors or warnings if use strict; and use warnings; are used?
Does calling parallel ... perl ./test.pl work any better?

If none of that helps, please post the ./test.pl code.

Ken et al Thanks for the suggestions: the script is executable and has a compatible shebang, it runs successfully on both machines using strict. The original script is not trying to read from STDIN, so I can get away without passing arguments with parallel The suggested syntax does not work either unfortunately The test script is purely so I can get parallel working in the first instance so it just prints "Hello world\n"!
