It would not be hard to load or save particular history files based on a variable, then set the terminal title to a name. That name would have to be preset somehow, though... like different icons or key commands to start the different sessions. > It saves the 200,000 last commands, and merges the new commands with > the previously saved ones. Yes, along with adding 'history -S' to .logout. I'm starting to wonder about adding some history commands to be executed as part of the prompt, so that each session shares the history immediately rather than only adding to it on logout. Maybe 'history -S; history -L'? (Untested.)

The requires parts are part of the shell, if I remember correctly, and you can ivoke them with "predefined settings", maybe derived from some X-related ID (-class parameter for Xterms for example, or examining the parent xterm's properties with the "xprop" command). > > It saves the 200,000 last commands, and merges the new commands with > > the previously saved ones. >=20 > Yes, along with adding 'history -S' to .logout. This seems to be exactly what I need. I've made those settings and will check. Additional background: Sometimes you want to check a user's history because he claimed "I've tried it, but it doesn't work", of course without providing commands and output. So you're checking his shell history file. The problem: The file that is present could be the one related to the shell from what he did _not_ execute the command. With a merged approach, you could review all commands. > I'm starting to wonder about adding some history commands to be executed= =20 > as part of the prompt, so that each session shares the history=20 > immediately rather than only adding to it on logout. Maybe > 'history -S; history -L'? (Untested.) For interactive shells, ~/.cshrc could contain a if ($?prompt) then ... settings for interactive shells here ... endif block. As if someone would _script_ with the C shell! ;-) Additionally, there's a mechanism to take actions before and after the prompt is written ("between commands"): You can set up those in .cshrc as well: alias precmd '<happend prior to executing a command>' alias postcmd '<happend prior to printing the prompt>' They can also effect the setting of the prompt itself (by calling "set prompt =3D '<something>'") if this should be needed. --=20 Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
