Is it possible to have a unique .bash_history file per host?

bash nfs

My home directory is mounted on an NFS mount. The commands I use on one machine are usually quite different to those on another. Is it possible to have easy host write to it's own history file?


Solution 1:

It certainly is. You just have to change the name of your history file on each host. In your .bash_profile put something like:

export HISTFILE="${HOME}/.bash_history.`hostname`"

Solution 2:

There is the environment variable HISTFILE, which controls where the history file is. You could try to create a login script that resets HISTFILE according to your hostname/IP.
