What version of Perl is required?

When I try to run parsyncfp:

Can't locate Env.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at ./parsyncfp line 12.
BEGIN failed--compilation aborted at ./parsyncfp line 12.

perl --version

This is perl 5, version 16, subversion 3 (v5.16.3) built for x86_64-linux-thread-multi
(with 39 registered patches, see perl -V for more detail)

Nevermind, solved with the help of SO:

sudo yum install perl-Env

Thanks for making parsyncfp!

Note the bug about the suspend/unsuspend. I'm closing in on fixing it, but haven't finalized it yet. hjm

Is the bug referencing cases where the machine is a laptop or VM which then goes into suspend power mode?

Oh, after reading the --help more, I understand. I will set --maxload to 50 (nCPU=54).

Thanks @hjmangalam!

Or set --maxload=400 to make sure it doesn't hit it. Typically on a X core system, each rsync will take up about 1core's worth of load (depending on options, offload engines, etc). Not actual cpu usage, but load (from loadavg). Also, I've never used that high a number for pfp so I'd be interested in what advantage you see vs a lower (saner) number ;) Thanks for trying it. hjm Harry Mangalam, Info[1]
