I’ve been frustrated before with differences in output from the which command across different platforms (Linux vs. Solaris vx. OS X), with different shells possibly playing into the matter as well. type has been suggested as a better alternative, but how portable would that be?
Suppose I have a thousand or more instances of any process (for example, vi) running. How do I kill them all in one single shot/one line command/one command?
I use Bash as my interactive shell and I was wondering if there was an easy way to get Bash to run a system command instead of a shell builtin command in the case where they both share the same name.
Sometimes I define a function that shadows an executable and tweaks its arguments or output. So the function has the same name as the executable, and I need a way how to run the executable from the function without calling the function recursively. For example, to automatically run the output of fossil diff through colordiff and less -R I use:
I’m wondering about the way Linux manages shared libraries. (actually I’m talking about Maemo Fremantle, a Debian-based distro released in 2009 running on 256MB RAM).
My understanding of load average lead me to be quite shocked with my current system. The CPU in my workstation is an i7 with hyperthreading enabled, and cat /proc/cpuinfo produces 4 ‘cpu’s.
I’m having difficulty locating a comprehensive up-to-date list of error codes from Bash. e.g.:
I’m looking for a way to limit a processes disk io to a set speed limit. Ideally the program would work similar to this:
I have Gentoo x64 installed with Grub2 on my MBR drive. Today I installed FreeBSD x64 9.2.
Now I’m in Gentoo and trying to add FreeBSD to grub2 menu list.
So I well understand that exit code of 0 is considered success in running of a program. Then we use this in bash scripts with logical AND and OR to run the next program based on the exit status of the first program. A good example can be found here: https://unix.stackexchange.com/a/187148/454362
