I'm trying to write a function, I'll call it escape, that will behave like this: % IFS=$' \t\n\000' % escape FOO $IFS FOO=$' \t\n\000' In other words, escape takes two arguments, and then, taking the first one to be a variable name, it prints out a line a zsh source code in which a variable of...

I used to be able to copy&paste (or type if I load respective keyboard layout) any kind of characters (eg. é ö ñ ß و 好) in my console/terminal. Now I bought a new computer and it does not work any more, only English/ASCII characters (but in other programs, e.g. firefox, it still works). Dis...

I recently built a very simple test environment with oepnSuSE. As I tried to configure a shared directory, wihtout using ACLs, but with SetGID on that directory instead for some reason, I noticed that the default umask for every user is set to 022 (i.e. 755 on directories & 644 on files). T...

I bumped onto this one question, and I doubt it can be salvaged by being updated or having a warning attached. I think it should simply be deleted.

I have an Asus EEE 1015PX netbook. It runs Linux (debian) without any powersavings enabled. E.g. no harddisk idle/spin-down tooling is running.

I'm currently looking to move our system from RHEL 5 to RHEL 6, but I've run into a snag with unexpectedly high CPU usage on the RHEL 6 machines. It appears that this may be due at least in some part to the use of select to do an interruptible sleep. Here's a simple example that shows the behavio...
