Ubuntu :: Change Nice Priority At Launch?
Jan 12, 2010I'm currently running on a really old computer with one proc and little memory. It's just enough to get skype running but it only works well enough if I change the nice level to -5 or lower. Now the person that uses skype in the house is really the wife, I don't want to teach her how to open htop in command line, fine the pid and then use the correct command to change the nice.What I am looking for is a script (sorry I don't know thing one about programming/scripting) that will change the nice priority periodically for all pid that are skype. This way call processes will get reniced as well. I know better then to run it as root/sudo, but I am at a loss (even searches came up with not much) on how to do this.

Feb 21, 2010I have created an error logger thread in my application using pthread_create(), I want this thread to have a lower priority than my application's priority so that the application would run properly. Is there an easy way to do this? I know that we can change priority for thread created with policies FIFO or RR, since I don't set the policy for my application, I don't know what to set for my thread.

Jan 9, 2010The algorithm for reading and writing disk blocks use the algorithm getblk to allocate buffers from the pool. In the algorithm getblk, if the kernel removes a buffer from the free list, it must raise the processor priority level to block out interrupts before checking the free list. Why ?Where can i find the C implementation of the above algorithm for buffer allocation in the linux source code ?

Jul 21, 2010I need some direction on a small scripting question. I've been doing some development and storing the code on a network drive with multiple user access. My development is getting complex enough that it is time to set up a svn repo for it. I would like to set up a little script (if possible) that prints a message/reminder to whomever is accessing the code directory stating that the code is ultimately stored in svn and any changes need to be checked in, etc. Is there a way to have linux print a message to the screen based on a 'cd /specific_dir/' command? So far google is mum on the topic. Using Debian and bash shell.

Programming :: Ls -R Without Changing Access Time/date?
Aug 31, 2010I am using cygwin in order to test a bash script that uses the ls -R command. When I use this, the access date of the subfolders are changed, and I need them to remain what they were before the command was run. I don't have access to a legitimate Linux system, so I'm not sure if this is the fault of cygwin or the ls command. The script is being used to find the last access date of all files underneath several subfolders and then return the latest date found in each subfolder as the last access date for that subfolder. For some reason, some of these folders have files in them that are newer than the folder's last access date, so the script is meant to give us a list of the true last access date for these folders.

Programming :: Changing Color Of Output From Bash Script?
Apr 22, 2010I am writing a bash script that utilizes the output of another script (which I will refer to as script#2.) Script#2 is not owned by me, I cannot modify it. All of the output from script#2 is blue, which makes it difficult for me to read.
I would like to have the output of it changed to grey. Is there a way I can do that in my script? A command I can pipe the output to?
Edit: One other question related to this. I put a trap function in my script that works well. Script#2 essentially runs a tail -f. When I ctrl+c to stop it, it stops script#2 and never calls the trap in my script. Is there any way I can work around that?

All is running well, but my nice values are all set to 0. Is there a script that handles these at boot time? How can I reset them to "appropriate" or "normal" levels (e.g. not all at 0)? I know in other installs, my nice levels vary depending on the process and the user.

Programming :: Bash : Searching For Info And Changing The Color Of Keywords In The Results?
May 5, 2011(bare with me as I am sort of new with scripting) I am trying to figure out how to run a script that does a basic chkconfig and to get only those services that are running, but changing the color of "on" to red in my output file. Here is what I am working with so far:
Quote:
#/bin/bash
RED=$(tput setaf 1)
BLK=$(tput setaf 0)
[code]....
*I had to substitute a "-" and <colon_symbol> for ":" in front of the on's, because the forum thought they were smiley faces (i.e. n) how to make the "on" to be red while the rest of everything remains in black text. I have been trying to read up on sed and awk, but it is still pretty much a mystery to me right now. There will be other things in the output file that I wouldn't want a rogue "on" to be in red, so just the instances of "on" in that one chkconfig return.
Fedora :: Since TeamSpeak 2 Doesn't Come In A Nice RPM Anywhere
Oct 21, 2010Since TeamSpeak 2 doesn't come in a nice RPM anywhere, I am under the assumption that I have to go to TeamSpeak's website, download TS2, and install through their script. I did all of that, and I can successfully launch TeamSpeak, however there is no sound whatsoever. No mic, and no speakers either. TeamSpeak automatically forces mute microphone and mute headphones on me, and I can't uncheck them. Therefore, something must be wrong with TeamSpeak and my sound setup.
