ps: `ps -ef` output formatting differs from oracle

[matt-dz]

Summary

rshell and the oracle produced different pwd pwd; uname -a; ps -ef | grep -E "kubelet|containerd|elasticsearch|kafka|mezmo" | grep -v grep results.

Command

pwd; uname -a; ps -ef | grep -E "kubelet|containerd|elasticsearch|kafka|mezmo" | grep -v grep

Reduced command shape: pwd; uname -a; ps -ef | grep -E "kubelet|containerd|elasticsearch|kafka|mezmo" | grep -v grep

Expected (oracle)

Exit code: 0

QA triage correction: this was originally filed under pwd, but the meaningful non-uname diff is from ps -ef output formatting. The uname -a stdout delta is tracked separately in #522.
