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.
35=8 39=1 38=1000 32=13 14=754 31=1.11 44=1.1 100=AMEX,ISE
35=8 39=1 38=1000 32=151 14=205 31=1.1 44=1.1 100=AMEX
35=U 39=2 38=1000 32=45 14=184 31=1.1 44=1.1 100=AMEX,ISE

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).
View 6 Replies View Relatedneed 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.
I'm trying to count words in a text file that has a comma as separator. I know that I must user wc -w, but wc uses space as a separator
View 2 Replies View RelatedI have a file of the formcol1, col2, $330,000, col4 ...col1, col2, col3, col4 ..col1, col2, $230,000, col4 ...The comma within the currency value causes the column to display unevenly when I open it so I want to remove it. I think I should be able to use the sed command but I am not sure extactly how. All the values have 3 digits after the $ and before the , so have triedsed -e 's/$[0-9]*,/ but I am not sure how to 'replaced with the string found just without the comma'So two guestions:1. Is this a good way to do it?2. How do I do it

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:

D,E,
F
G,H,I
becomes:
A,B,C
D,E,F
G,H,I
I have a data file with the following format 0 i j # # # # with other random lines of text to be filtered out.The following script works when there aren't many #s, but it shuffles long lists of data.

I need to occasionally touch a file with the current timestamp as the filename. I would do so this way:
touch `date "+%Y-%m-%d_%H-%M"`.txt
However, I'd like to define an alias for this. When I try adding to the bashrc this:
alias td="touch `date "+%Y-%m-%d_%H-%M"`.txt"
the result is that the filename is the same during the entire session, since the `date ..` gets calculated just once during login...
How can I get the command to expand only when I call the alias? Or must I use a function for this?
Usually when I need to replace some lines in a file, the first tool that comes to mind is sed -i:
sed -i 's|tool:.*|tool: some-tool|'
However, it's inconvenient when there are . characters in the replacement string:
sed -i 's|host:.*|host: 127.0.0.1|' Is there a better tool for this case?
Need little advice running this command.
watch -d 'ps aux | awk '{print $4" "$11}' | sort | uniq -c | awk '{print $2" "$1" "$3}' | sort -nr | head'
I get this error message from AWK. awk: cmd. line:1:
{print awk: cmd. line:1: ^ unexpected newline or end of string
I have tried all the usual by trying to escape the single and double quotes in the command but same result. The end result should be the a listing of memory hungry processes that are scanned every 2 seconds (watch default value).
i have a cd that shows you an empty directory unless you mount it for the joliet extensions - specifically 25 2f 40. It uses wide characters with the high half null.

Fedora 14
When I started I took the defaults and ended up with Evolution.
I have never managed to get it set up to send. It and godaddy are on diffferent planets.
Having used Thunderbird in the past, I downloaded it and it automagically set itself up to send and receive.
So now I use Thunderbird - BUT - when I click on a link in an html page - the mailto macro sends me to something other than THunderbird - perhaps Evolution - and nothing gets sent.
So how do I tell the system that when i click a mailto in firefox I want Thunderbird?
PS I think I found it. In firefox - edit - preferences - applications tab - mmailto - it said Evolution. I changed it so say /usr/bin/thunderbird - will now test it.
YES - Seems that asking a question triggers my brain on how to resolve it. Sorry to waste your time.

E.g. The line "tetris cat dog test cactus stereotype"

The following regex doesn't do the job because it can;t distinguish words very well.

I would like to replace gvim with vim in the terminal. One of the nice things about gvim is that it is able to display text using italics.

I have a ton of files that are timestamped directories. These all look like2011-06-24_13.53.36 // a directory name for june 24th, 1:53:36 pmI have thousands of these directories. I want to do operations on some of the older ones. Let's say I give it a string for date time that matches that exact format, like i'll give it2011-06-25_00.00.00 // june 25th, 12amI want to find all the directories BEFORE my time. So if i give the string for 12am on june 25th, i want to find all the directories before then.If not i can find EVERY directory i have like this and then filter after wards. The created/modified dates are not tied to the actual timestamp im looking for (that would make this easier)

Is there tool or a regexp that can convert shell escape characters to HTML code?
As an example, here is a logfile from GNU screen:
Which I would like to convert to something like this:
And send as HTML e-mail to an e-mail address, to archive my work.
Here is a related question, which shows how to convert it to regular text, but it would be nice to convert to HTML and not just throw the escape characters away.
I'm fairly comfortable with emacs but I can't seem to find how to do this. I deal with a lot of text files and find myself performing a lot of regular expression replacements to correct the formatting of the text -- or to extract certain tidbits of data from large ugly-looking files.
I know how to perform a regular expression replacement in one buffer at a time. But how do you perform a regular expression search and replace across all open buffers? I have found a method to perform a regex search and replace across a directory by marking files but I need to do it in the open buffers.
I use the Actions feature of KDE's Klipper utility to run certain commands when I copy something into the clipboard that matches a particular regular expression. Unfortunately, I have to turn on Enable Clipboard Actions and select the command from a menu every time I copy something that I want to run the command on. I'd like to have that command run automatically instead.
You'd think this was possible, as there is an automatic checkbox in the action settings dialog box:
Unfortunately, that appears to do nothing. The documentation included with Klipper does not indicate what that checkbox is supposed to do.
Is it possible to configure Klipper to run a command automatically if the contents of the clipboard matches a regular expression? If not, is there another way to accomplish this?
I am tryng to get values BBA 204- BBA 324 from a log file.
this is my script:
zmore log.gz | perl -nle 'print for m/BBAs[2|3][0-9][0-4]/g' | sort -u | perl -ne 'print if /^BBAs204$/../^BBAs324$/'
the first perl one liner gives me everything from BBA 200 to BBA 394, and the second perl one liner cuts it down to BBA 204 to BBA 324
Is there a elegant regex that will allow me to skip the second perl one liner and just take out the BBA 204 - BBA 324
