Developer Shell Shortcuts Disappear

Three operators report that ll output on the ops host differs from what the handoff runbooks show.

Briefing

The platform team pushed a dotfiles sync overnight, and by the morning handoff three operators had pasted runbook steps that assume ll shows human-readable sizes.

In this shell ll still answers, which is why the first responder called it a false alarm.

New sessions pick up whatever ~/.bashrc says, and that file changed in the sync.

It is a small problem, but it is slowing down an active handoff.

The fix is yours to find: hints, the recovery checks and the debrief unlock inside the incident.

How it plays

  1. 01

    Get paged

    The alert fires and the clock starts. Read the page and the briefing.

  2. 02

    Investigate

    Work in a simulated shell with realistic output: logs, configs, services.

  3. 03

    Fix it

    Change the system the way you would in production. Hints are there if you get stuck.

  4. 04

    Prove it

    Automated checks verify the recovery, then the debrief explains what happened.

Your pager is ready.
