Also, currently users $HOME are synced with NFS, woulld JP's Automatic
method work? Ie. If a user types in a command in server1, will that be
registed in history for server2?

I don't see why not. ~/.bash_history is just a file, and 'history -a/-n' write/read that file. So if it's the same file over an NFS share, that should work.

Except... Something I had not considered before--I don't know if there is any kind of locking going on here. So a $PROMPT_COMMAND or NFS share might result in .bash_history file corruption due to collisions. I guess if you are doing the manual thing over NFS you'd be OK unless you have a lot of latency someplace and try to do it too fast.

I'll see if I can find out.

Later,
JP

Microsoft has single-handedly nullified Moore's Law.
Innate design flaws of Windows make a personal firewall, anti-virus
and anti-malware software mandatory. The resulting software arms race
has effectively flattened Moore's Law on hardware running Windows.
