General :: Output Pid's From Ps To A Comma Delimited File?
Apr 7, 2010need to monitor pecific processes over a time frame in terms of the amount of memory and cpu usage it utilizes. I can do this using the top -p <pid> option and using ps to retrieve the pid's. However, seeing that the pid's might differ and it needs to be run on about 13 different machines, I would like to write a script for this that can be run at set intervals. My problem that I have is this:
- When running top -p <pid> I can specify a comma seperated list of the processes required to monitor at that specific time.
- I can use ps -ef | grep <process> | grep -v grep| awk '{ print $2 }' to retrive the list of pid's and output this to a file.
However, how can I output these to the file as a comma seperated list without having to manually do this every time? The reason for this is (an example), lets say I want to monitor the cpu and memory usage of postgresql as well as all its child processes, then I would ps grep for postgres and get the list of pid's for instance.This list then needs to be passed to top -p as a comma seperated list of pid's I suspect that awk or sed might have some options available for this but I do not know this well enough.
General :: Parsing Delimited File And Variable Scripting?
Sep 23, 2010I did some searches and after a few hours was able to get what I needed. What I didn't find was a fully encompased means of what I'm used to in the windows world in working with delimted files. Hopefully this is helpful to others and if there is something better or leaner way, even better.We have an issue where managing printers, just viewing on RHEL w/ sys-conf-prtr we lose any number of, up to ~30 printers from lpadmin. Rather than stare and compare to find the missing ones, I wanted to make an intuitive script. This is what I came up with.

Programming :: Bash - Reading Csv Delimited File To Array And For Further Manipulation?
Jan 6, 2010I am trying to do this:
1. Read csv delimited file line1 and store all values in array
2. Use the values stored in the array and replace values in other text file with them
3. read line2 in the cvs file and repeat the process
4. Do above for all lines in the cvs file
for example:
file1.cvs content:
text1,text2,text3,"text 4"
a1,a2,3,"a 4"
file.txt content:
some text $array1$ some text
some text $array2$ some text
1. read line 1 - text1,text2,text3,"text 4" put each value in array X[] lines that contain spaces in cvs will have double quotes
2. read x[1] and replace value $array1$ (in file.txt) with x[1]read x[2] and replace value $array2$ (in file.txt) with x[2] and so on
Can above be accomplished in BASH and how?

General :: Splitting Text File Into Several Parts By Line Count
Sep 21, 2009I have a utility that works with files. The utility is crashing at after about 120 files. The input to the utility is a file containing a filelist. I want to cut the file with the file names in it to seperate files containing about one hundred or so. My thought was to determine the number of lines/100 and then use head and delete to create temporary files to run the utility multiple times to prevent the crash. When I tried to create a variable using the wc -l command the output gives me the number of total lines but it also includes the filename of the input file. (873 Filename.txt) I can not figure out how to remove the Filename.txt from the variable.

Oct 30, 2010I have to computers: 'A' (linux) and 'B' (windos). On 'A' I have a linux system that i copy over to a movable disk on which i install the lilo bootloader. Now when I move the disk to 'B' I am able to boot into the new linux system, however I would like to have an item in the lilo boot menu from which I can boot the windows system on 'B' also. And now the tricky part: I would like to create this item when the disk is still on 'A' where windows is not present.
I have tried using "disk = /dev/hda1 inaccessible" without any luck.Is it possible to "cheat" lilo into adding an item pointing to a disk that is not present on your system ?
