[Discuss] Reviewing history command output for productivity

[noel at natnix.com]

You guys and your wacky multiple terminal windows.  Kiss the Gnu, live
in Emacs.  I run bash in an Emacs buffer.  I rarely need more than one
bash buffer, since you can open mutiple buffers for files and man pages.
Since cutting and pasting is so easy in Emacs, if I need to reuse a long
shell command I save it from the shell to a notes file, then I can paste
it back in my shell buffer later.  Yes, I know you can open multiple files
in vim too, but having an umlimited buffer by running your shell in your editor
makes things like this much easier.

What am I saying?  This is Linux where pain is the name of the game.

Looks like you can do what you want in tcsh:

but accorinding to the bash manpage, history files are only saved when
the shell exits.
