Apr 11, 2011I have a directory that has a bunch of files and directories under it that I need to correct the filenames of. In fact, I plan on running this as a cronjob to keep checking filenames for certain characters. I want directories and filenames with spaces or pluses (+) to have those certain characters replaced with underscores (_). I know that this will involve sed but I'm not sure what else. A simple shell script would handle it.

Jun 14, 2010I am running a simple script that I copied from slug.ceca.utc.edu/docs/2009-3-26-linux-server-health.pdf and edited with the names and paths of my own servers. I don't know much about scripting (re: nothing) but I wanted to try and be efficient in my new role as a Linux Sys Admin. The script was saved to root's home directory and runs as part of root's crontab once a week. The script runs with no problem, but it doesn't actually seem to run all of the commands contained within. It skips some in the middle and the end and I don't know why. The script itself is this:

Programming :: Check If The User Is In Correct Directory Before Executing Bash Script
Dec 10, 2010I have been searching for 90 minutes for something that I "think" should be fairly easy. I'm pretty new to Bash Scripting so I could be completely wrong.

The only thing I need to add to it is a "check to make sure the user running the script is in the /tmp directory".

Programming :: Pthread_mutex_lock Returning EDEADLK For A Mutex Of Type PTHREAD_MUTEX_RECURSIVE

pthread_mutex_lock.c:275: __pthread_mutex_lock: Assertion `(e) != 35 || (kind != PTHREAD_MUTEX_ERRORCHECK_NP && kind != PTHREAD_MUTEX_RECURSIVE_NP)' failed.
all my mutexes are of type PTHREAD_MUTEX_RECURSIVE and as per all the man pages/tutorials, EDEADLK error is to be returned for mutex of type PTHREAD_MUTEX_ERRORCHECK ONLY.I really should not be hitting this assertion.Would some kinda weird memory corruption be causing this? Or is there something more to it that I am not aware of.I am using linux kernel 2.6.2, glibc 2.5 on PPC.
Programming :: Poll() System Call Not Returning When The Socket Is Closed Locally?
Sep 29, 2010we have a multi threaded program on Linux where one thread is waiting on poll() system call with event set to POLLIN, & another thread has closed the same socket fd (which is passed to poll) , but the poll() did not return, is this the expected behavior? From man page of poll we found that the poll should return POLLNVAL if the socket fd is closed, is my understanding correct or is there any bug in the poll()?In Solaris we observed that the poll system call is returning with POLLNVAL if the socket is closed.
