Hello everyone,

I am trying to setup a Gitlab runner that will SSH from a RHEL into my z/OS USS and execute commands via Rocket Bash.

But I am hitting some issues that seems like an encoding issue when my runner is firing the commands and is not getting read correctly on Rocket Bash

Running with gitlab-runner 17.3.1 (66269445)
  on SSH Runner abc123asif, system ID: a_bcde123452c1

in my etc/profile file I have also configured the following settings:

export _BPXK_AUTOCVT=ON

Changing the locale of the z/OS and also my RHEL

z/OS - locale from C to IBM-1047

LANG=En_US.IBM-1047
export LANG

RHEL - locale from UTF-8 to ISO8859-1

LANG=En_US.ISO8859-1
export LANG

I have also tried to set LC_ALL in my /etc/profile of z/OS to use IBM-1047 but am getting the below error:

bash: warning: setlocale: LC_ALL: cannot change locale (En_US.IBM-1047): No such file or directory

Please make sure that /etc/profile and any other startup files that you are using are tagged according to their encoding. You can tag a file using the `chtag` command. If the problem persists, create a ~/.profile file using `touch ~/.profile && chtag -tc 819 ~/.profile && echo ‘_BPXK_AUTOCVT=ON’ >>~/.profile` (make sure to move any existing ~/.profile before doing this, you can copy the contents of your old ~/.profile into the new one after you create the new one).

Bash is an ASCII-mode program, so it does not support running in an EBCDIC codepage, we recommend running in a UTF-8 locale like En_US.UTF-8. It is still able to interact with EBCDIC files and utilities while running in a UTF-8 locale so you lose no functionality by using a UTF-8 locale.
