So I’ve had lots of problems using a multi-tab xterminal, for the casual user I’m sure they’d not even notice them, or think I’m silly, but when you spend all day in a shell they become less so. Historyone of the big problems I’ve had is with history. see when you close a shell then it writes the history. well if you have 5 tabs open each with with a super long history they’ll write those histories out in the order they close in. basically what happens is all the history saves at once so one of your open shells histories will be before another’s and if each has like 50 entries it can be quite a way back. In fact I’m sure I’ve had it happen where parts of my history was lost. So what do you do? you have to separate them per tab. One way to do this is with gnu screen. I don’t like screen’s history because it records the output of the terminal as well as the command, so this wasn’t a good solution for me. The solution is that each tab must have its own history file. Well how do we do that? before I get to it I have another problem.PS1, umask, and default groupI also have a need to have different settings depending on what I’m working on. If I’m working on files that need to be read and written to by my web server they need to have a different group and umask. first I solved this by su - to a different user, then I solved it by having different bashrc’s but neither fully solved the history problem.howto do itfirst you have to have one konsole profile for each of the different settings you need. so I have one for web development called webdev. Then you have to add an environment variable to it I’m going to call it KONSOLE_PROFILE and set that to whatever your profile is called. Neither name really matters so long as they don’t conflict with others. Then you need to code your bashrc (or other shell to work with it). I have a shortened sample bashrc that you can use in a gist– This work by Caleb Cushing is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Unported License.
