I use many of these commands quite often. They’re immensely helpful when one wants to do a lot of remote work on a computer, or simply access resources on a remote machine (Linux or otherwise).

I use this command to change the resolution of my EEE 1000HE from 1024×600 to 1024×1024 which allows me to work well with large web pages, though I must pan-n-scan the desktop (which runs past the borders of the monitor), it’s worth it. Not every EEE PC is built the same, nor do they use [...]

Execute (3) scripts. I suppose this could be done all in one script, but sometimes one wants to examine the results after each phase. This will actually work (in principle) to do any command on all files in a directory that have a predictable pattern. Don’t forget to chmod +x ./script-name on each. Script 1 [...]
