• Path managment in Linux programs

  - by petersohn

  I have a newbie Linux programming question. Suppose I have a project that uses Autotools for compiling and deployment, and I have data files that are to be installed in a location like /var/something or /usr/share/something etc., but in Autoconf, I can change these installation paths. How should the program find these files? How does it know where they are actually installed (if anywhere, since the program should work even if not installed, but run from where it was built)?

• Linux Scheduling Mechanism in 2.6.22?

  - by Mazen

  Hello, I'm doing some kind of performance evaluation using two different vanilla Linux kernels, 2.6.22 and 2.6.31, since I assume each of them uses a different scheduling mechanism: 2.6.22 uses the old O(1) scheduler, whilst 2.6.31 adopts the CFS. Could anybody confirm the correction of this assumption?

• Equivalent to GetTickCount() on Linux

  - by Matt Joiner

  I'm looking for an equivalent to GetTickCount() on Linux. Presently I am using Python's time.time() which presumably calls through to gettimeofday(). My concern is that the time returned (the unix epoch), may change erratically if the clock is messed with, such as by NTP. A simple process or system wall time, that only increases positively at a constant rate would suffice. Does any such time function in C or Python exist?

• Finding process count in Linux via command line

  - by Moev4

  I was looking for the best way to find the number of running processes with the same name via the command line in Linux. For example if I wanted to find the number of bash processes running and get "5". Currently I have a script that does a 'pidof ' and then does a count on the tokenized string. This works fine but I was wondering if there was a better way that can be done entirely via the command line. Thanks in advance for your help.

• Emacs, Linux and international keyboard layouts

  - by sabof

  Is there an easy way to use emacs key-bindings when you are using a not-English (Russian) keyboard layout? Whenever an international layout is on, all keystrokes are interpreted literally, M-? instead of M-a. As a result I can't use commands. It would also be nice if Linux could interpret non-prefixed and shift-prefixed keys according according to an international layout, while keeping the rest English.
