I'm migrating some home-grown parallel processing scripts to GNU parallel. One
feature I miss from the old scripts is the ability to tag each line of output,
so you can see exactly what produced them.
A simple example:
$ parallel 'find {} -print | wc -l' ::: /etc /usr/local
4161
3792
$ parallel --tag 'find {} -print | wc -l' ::: /etc /usr/local
/usr/local: 4161
/etc: 3792
$
Is there a way to easily do this with parallel? I cobbled together a "--tag"
option to get me by (and I'd be happy to share), but I'd prefer to not maintain
any local patches.
