I try several ways
grep -v '^cc$' data.txt > output.txt # works but to another file

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:

find(&check, $dir);
sub check {
if ($_ =~ /.xml/){

I have a huge binary log file. There are lets say 4 id's that I want to find in a log file. I know that those 4 id's will be present in the log file and I also know in what order they will be present. I want to find 1st id from the log then 2nd id and then third id and so on..
Simple/inefficient solution is: Loop through the id's and then grep in the log file. Problem with this solution is for each id grep will search from the beginning of the file.
Better/efficient solution would be: Sine I know the order in which id's will be present in the log file. Loop through id's, grep 1st id and then move on to grep 2nd id and so on...this way I can grep all id's in one pass. Is this solution possible ?
I have 500000 + values to find in log files and I have to find efficient solution for it.
I am trying to compare a list of patterns from one file and grep them against another file and print out only the unique patterns. Unfortunately these files are so large that they have yet to run to completion. Here's the command that I used:

Code:

>FQ4HLCS01B40PB
>FQ4HLCS01BT43K
>FQ4HLCS01CB736
>FQ4HLCS01BU3UM

how to increase efficiency or use another command?

Actually I have two data files one of them contains 44406 and the other one has 12066 rows and I want to check whether the difference between the components of two specific columns is less than a threshod but I have simplified it here. I had written this code and then I have realized that this code just goes through the number of rows as the same as the first.txt file and ignores the rest. I could not find the problem yet.

Write a program that reads the data from the music.txt file and store it in a data structure. To implement this data structure you must use an array of songs and each song must be represented by a struct with appropriate fields. So far all I can do is open to file to read it (very simple I know) but so far is it correct?

I have a script which uses a Menu file (containing several different Menus). I start out with
Code:
Menu=Main
and grep my VRMenuData file for
Code:
$Menu:code:$txtring
where txtring contains the value entered from the keyboard, and cut that line for the code I want executed. So my data looks like:
Quote:
Main:code:1:declare Menu=Download
Main:code:2:soffice -calc VRSched.ods
Main:code:3:echo Load Refresh Menu here
My code acting on the data looks like:
Code:
`grep $Menu:code:$txtring VRMenuData | cut -d: -f4`
When I chose options 1 thru 3, that executes with no problem (Menu=Download does not work). The program sees into field four, but field four is not able to see outside itself. For instance:
Code:
Download:chan:
Download:pitm:1:echo $numpi. Return to Main Menu
Download:pitm:2:

Code:

32. Return to Main Menu

How to remove alternate char from file using shell script? If the file content is "1234567890" the output file should be "24680".

I'm trying to come up with ideas for a simple way to strip a specific "entry" from a text file.I know tools like sed and perl can remove specific lines from a file but I haven't been able to come up with an elegant way to do my group of lines.In my file, the first "Location" line and the "SVNPath" line should be unique every time... but are they enough to strip out the whole set of the group plus the trailing one line of white space separating each group? Add to this, my file will grow as new entries are added (always appended to the end) but new entries will have the same formatting.
