I read your post, and slapped together the following, which goes into
~/.bashrc. Warning... some backtick expansion included here. Is there
a simpler way to find out which tty or pts you're running in?
# If running interactively, then:
if [ "$PS1" ]; then
# Set up a separate HISTFILE, depending on which tty we logged in
# from. Convert slashes in tty names (e.g. "pts/0") into underscores.
mytty=`ps -ef | grep ${USER} | tail -n 1 | sed "s/^.\{30\}//
s/ .*$//
sx/x_x"`
export HISTFILE="${HOME}/.history_${mytty}"
The command figures out which tty/pts we're launched in, and sets a
history file containing the session name. One booby-trap is forward
slashes, which aren't legal as filenames (they're interpreted as
directories).
