Original Pull Request: https://github.com/netbirdio/netbird/pull/5090

State: closed
Merged: No

Describe your changes

Edit: sorry for the spam; I took a second pass at this for a cleaner implementation.

Fixes #5082 by using non-truncated user field output from ps instead of getting uid and converting with id.

Using -o 'user:256=' instead of --no-headers -o '%U' prevents truncation up to at least 256 chars (the username length limit)
Keeps simplified/refactored code from 9bd578d, avoiding the use of sed by using word-splitting on a known-format value.
Tested script and ps invocations against multiple current and history distributions, including Alma, Fedora, Debian, Ubuntu
Validated against shellcheck
