This is not the case.

I use 5.34.0 on Ubuntu 22.04 and I do not have the problem. I have compiled 5.36.0 on the same system, and I still do not have the problem. This tells me that it is a problem in your environment.

I ask you again: Please follow https://www.gnu.org/software/parallel/man.html#bug-dependent-on-environment

Given the output from uname, it looks as if this might be an Amazon issue. But that will be easier to determine if you follow https://www.gnu.org/software/parallel/man.html#bug-dependent-on-environment

Thanks for your report.

I cannot reproduce your problem, neither on 5.34.0 nor 5.36.0.

Hi,
I'm getting below error while running parallel tool on Perl 5.36.0

sysread() isn't allowed on :utf8 handles at /sv/app/parallel/product/parallel-20220922/bin/parallel line 11500.

Kindly let me know if the parallel utility is supported on Perl 5.30.0 onwards, if not let me know when are you planning to upgrade.

Regards,
Hari.
