Running parallel from perl system() with redirects

[Josef wells]

I have a problem that did not happen with version:

20130822

But does happen with:

20141122

This works:

parallel --joblog - ::: 'cat hello >& hello_log' > joblog 2>&1

But it doesn't work from inside a perl program.

perl -e "system('parallel --joblog - ::: \'cat hello >& hello_log\' > joblog 2>&1');"

joblog contains the error:

/bin/sh: 1: Syntax error: Bad fd number

You can take out the --joblog -, as that just makes something useful go to the parallel output redirect.

Any ideas?
