capturing bash history

[Nigel Hamilton]

Hi,

         I'd like to keep a history of all shell commands across all the
xterms I'm using but the ~/.bash_history only holds history from one
terminal.

         Any ideas on interleaving the shell history from multiple
terminals into one file?

p.s. it would be great if I could get this to work across multiple
machines too --- but I'll settle for one machine to start with
