This fails when using the perl version distributed with Ubuntu 16.04.1
LTS:
myfunc() { echo OK $*; }
export -f myfunc
seq 3 | perl `which parallel` myfunc
giving:
/bin/bash: myfunc: command not found
/bin/bash: myfunc: command not found
/bin/bash: myfunc: command not found
(parallel = GNU Parallel)
This fails when using the perl version distributed with Ubuntu 16.04.1
LTS:
myfunc() { echo OK $*; }
export -f myfunc
perl `which parallel` myfunc ::: 1 2 3
giving:
OK 1 (Surprisingly it works for the first job!?!)
/bin/bash: myfunc: command not found
/bin/bash: myfunc: command not found
It works as expected on the perl version distributed with Ubuntu 14.04.4 LTS,
Debian 7.8, Redhat 9, Centos 5, MacOS X.
I downloaded and compiled the pristine source for
perl-5.18.4 perl-5.20.3 perl-5.22.2 perl-5.24.0
on Ubuntu 16.04.1 LTS. Then this works:
myfunc() { echo OK $*; }
export -f myfunc
seq 3 | PERL5LIB=lib ./perl `which parallel` myfunc
PERL5LIB=lib ./perl `which parallel` myfunc ::: 1 2 3
All of this leads me to believe that a bug has been introduced in the
58 patches.
Failing perl version:
$ perl --version
This is perl 5, version 22, subversion 1 (v5.22.1) built for
x86_64-linux-gnu-thread-multi
(with 58 registered patches, see perl -V for more detail)
