I saw this comment:

In response to an answer.
It made me wonder, what do sysadmins do to prevent stupid mistakes, either for themselves or others?
In a previous organization where every change had to go through change management (even adding a host to /etc/hosts), we did copy/paste instructions for all change records. If it required additional commands/procedures that weren't in the record, a new ticket was opened.
