so i have a data file of a couple thousand lines. for example, my file will look like this (condensed of course):
Code:
something something 100 something 1 2 3
something something 101 something 4 5 6
[code]....
I need to kind of grep within grep. My input file would be something like:

and I need to find the first occurrence of hello before MY PATTERN (hello 9008 in this case), so the output should be:

I just upgraded from 9.04 to 10.04 and so far I have those problems:
1. Before, everything in my system was in English. Now, half is in English, half in another language (PCManFM, some menus etc). I tried setting up Language Support but it changes nothing.
2. Cursor themes work only when hovering the mouse over "X" buttons in the right top corner of the window. As soon as I move the mouse somewhere else, it goes back to default cursor theme, even though I tried selecting 5 different themes - same result.
4. Hibernation don't work anymore. s2disk saves image to disk and then it resumes it but computer stops on text message along the lines of "Resume completed successfully".
5. Changing volume with keyboard shotcuts no longer works.
6. Smplayer does not display picture anymore when playing movies. The view is just empty. I can only hear the soundtrack. It is using XV filter.
7. PCmanFM that used to worked flawlessly, now after going into 1 or 2 subdirectories stops reacting to clicks on file/folder list. Need to open new instance to be able to do anything and this again would become unusable after visiting 1-2 folders.
I'm not sure if this is the right place for this. I'm not sure which veraion of linux I have but it was the latest veraon bfor the recent update. I accidentally hit alt ctrl f11 and my comp went inyo the grub menu. I've tried startx and it does nothing. About half the commands I enter do nothing and the other half r not found or are incorrect. The only vommand thw actualley work is reboot. I searched for this and read a grub guide but it did no good.

how to increase efficiency or use another command?
Let me *try* and explain what I'm trying to do, and keep in mind aside from a little command line stuff I'm a beginner to any of what I'm asking about.
I have a directory structure something like this:
Code:
/usr/local/chatlogs/
webserver1/
1.chatlog
2.chatlog
[Code]....
So that whatever was captured in the () in the first part of the statement would be used in the 1 in the back part of the statement for every n.chatlog that might be in any of the /webserver directories at that time.

I am interested in using the grep method in the shell of my CentOS machine to obtain patterns from a file and use them to search through another file and highlight the patterns found. For example:
pattern file:
one
two
three
test file:
AAAAAAAAAAAAAAAAAAAAAoneAAAAAAAAAAAAAAAAthreeAAAAAAAAAAAA
I am not sure why this does not work..
tshark |grep 'string'
Gives me what I want but
tshark |grep 'string' >/tmp/outputfile
Gives me an empty file.
I'm storing a list of strings in a file and would like to read the file and pipe each line returned to grep which in turn searches a directory for files containing the string.However this is not returning any output.

When I type in the command directly, without using an inbetween variable, it works fine.
I would like to write a newline delimeted rules file using PCREs for use with the grep command. Grep has the option -f to obtain the search pattern from a file, and option -P to search using PCREs. However, these two options do not work together. The -f option only seems to work with fixed string rules.A friend previously helped me get around this limitation somehow, but I can't remember how he did it. I also would like the ability to add comments at the end of each rule in the file.

View 4 Replies View RelatedI am using File::Find to go through a very large tree. I am looking for all xml files and open only those that contain a tag <Updated>. I then want to capture the contents of two tags <Old> and <New>.
My problem is, after I open the file and do the first grep for <Updated> (which does work), I am unable to grep again unless I close the file and open it.
I did something like this:
Quote:
find(&check, $dir);
sub check {
if ($_ =~ /.xml/){
open(FILE,"$_");
if (grep{/Updated/} <FILE>){ # <-- works

I am trying to use grep to only tell me files that include both words matching in a pattern file. However when i specify:
grep -f <pattern file> <file>
It pulls out anything that matches one or the other.
Not both.

check

list ..
I want to grep each line one by one. like I want it to
grep "check" *.log
grep "try this" *.log
grep "word1" *.log .. etc how can I do this?
and maybe write the output to a file.
