My first thought was to put it in another shell script: export LOGFILE=logs/`basename $0`-`basename $1`...
I am writing a shell script to do a "tail" on a growing log file. This script accepts parameters to search for, and incrementally greps the output on them.

A process is considered to have completed correctly in Linux if its exit status was 0. I've seen that segmentation faults often result in an exit status of 11, though I don't know if this is simply the convention where I work (the apps that failed like that have all been internal) or a standard. Are there standard exit codes for proces...

We use the /proc and /sys file systems in Linux to discover various types of system configuration information. Typically, we spelunk around through the different files and directories until we find the information that we need. I'm wondering if anyone knows of a definitive resource that documents how one would navigate through the /pro...
I'm encountering the following error at unpredictable times in a linux-based (arm) communications application: pthread_mutex_lock.c:82: __pthread_mutex_lock: Assertion `mutex->__data.__owner == 0' failed.

Does blocking mode put that particular task in a "Process Wait" state, as i think non-blocking sockets needs a "busy-wait" or "spin-lock" implementation, explicitly from the user. Or blocking mode sockets are nothing but implicit-implementations of busy-wait by the kernel. In locking mechanisms like semaphores/mutexes/monitors a lock is...
