I have a fairly long list of data that I am trying to put into a math program (maple) but before I can do that I need to edit the format of the data such that at the end of every 25th line I add a comma. I would prefer a solution that uses vi, but if that's impossible sed would be fine also (or awk).

I have a CSV file that's created in an application that can't output lines longer than 250 characters. the data fields, all together, are longer than this. how would I remove the line break from every line that ends with a comma? For example:
A,B,C
D,E,
F
G,H,I
becomes:
A,B,C
D,E,F
G,H,I
I have a script that output all my data in to a comma-delimited file separated by ";"
Current Output:

View 6 Replies View RelatedI am looking at how to add particular text to a file in bash.Here is what I am trying to do:In the /etc/grub.conf file, I am trying to add "audit=1" (without the quotes) to the end of the kernel line...such as:kernel /vmlinuz-2.6.18-194.el5 ro root=LABEL=/1 rhgb quiet audit=1

I wish to add information to one of my files based on matching IDs,
Here is an example

So as you can see the ones that do not match are still present, and the ones that do match just have the extra information from file2.txt added to them.
I thought about using join but that only seems to join the ones that match displays thoes only. i would like all the information in the output file.

View 4 Replies View RelatedCouple of days I go I setup VLC using Kubuntu's graphic software manager, and installed the 3 plug-ins, one of which was related to pulse. After doing this sound stopped working in flash videos. I had read, not sure where, that Kubuntu didn't use pulse (which slipped my mind when setting up VLC).
So I make the mistake of removing everything which had pulse in it's name (again, via the graphic software manager). A message popped-up saying that some packages needed to be removed/edited (a LONG list, a big clue that I was doing something stupid I guess). I let it run it's course and after that it won't boot properly.
If I boot it normally it hangs at the Kubuntu screen with the five dots filling endlessly. If I press F1 it's stuck at "checking battery status."
Recovery mode boots, but the recovery option does nothing.
So I was wondering if I could boot into recovery mode and go into the terminal and add a live USB as a repository for apt, and try to salvage the install?
Or should I admit defeat and reinstall?
sometimes there are one, sometime there are two exchanges in this log file. the 100= is the stock exchange- if there are two, they are seperated by a comma. i understand how to escape a comma in a regex, but I am having trouble with combining it.

need 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.

View 2 Replies View Related- Off a vanilla F11 livecd install, I stuck a 3 at the end of my grub line to boot into runlevel 3. I have been doing this for as long as I can remember (since Fedora 3).

Has this facility (ie sticking a number at the end of the grub line) been changed and why is my grub line now broken even though I've gone back and deleted the 3?

I've been compiling a lot of games recently and most of them requires me to add libX11 to the linker command line. I can't think of nothing but to take a look at the Makefile and add -lX11. It works, but now, I'm compiling from a git repo, and I know the change will removed once I update the my working copy.To make it short, is it possible to add libX11 permanently to the linker command line?

I'm trying to compose a line of numbers each single digit taken from a variable eg: 1010001 each variable digit is either a 0 or 1 made from variable layer1 through 7. I need to add each layer variable to the last to compose the number with no commas or spaces and add it directly after the -p option in the show_command line. I used array and list and the commas mess up the command and inserting "pens" in the show command interpertes it literally instead of the list or array value?
