Hi ! I need some help with a script I am writing. I am trying to compare two files, the first file being in this format :

Code: Header1 Text1-1 Text1-2 Text1-3 Header2 Text2-1 etc... For each header, I want to check if it appears in the second file, and if it is the case print the header and the three corresponding lines of text. I found several methods for finding the header in the second f

i have a file that's about 2GB, i have to get the total number of lines in this file every 10 minutes.

the interval is not an issue. i just need the proper, most efficient way to do this.

any ideas?

i got the following from another thread on this site, but:

Code: awk 'int(100*rand())%5<1' file but this randomly pulls out 20% of lines in a file.

In the same spirit as this other question: cat line X to line Y on a huge file:

Is there a way to open from within Emacs (and show on a buffer) a given set of lines (e.g. all lines between line X and Y) from a huge text file?

E.g.

Is there any way to add lines to the pattern space of sed?

I know a bit about the N flag, but am not able to use it to do what I want which is:

read a file n lines at a time. If I find a match I quit else move to the next line. e.g.

I have a text file which is having 30000 lines in it. I have to create a xml file for each 10000 lines until all the lines in the text files are written. Also please help how can i get number of lines in the text file in a shell variable?

i have 3 files as below:

Code: [test1][test2][test3]

i want to print 1st,2nd,5th and 10th filed of 1st to 5th lines from each files into a line of an output file, so the result would be: [output]:

Code: {line1}(field 1 of line 1 from file 1)(field 2 of line 1 from file 1)(field 5 of line 1 from file 1)(field 10 of line 1 from file 1)...(field 10 of line 5 from file 1) {line2}(field 1

Hi All,

Need a small help in writing a shell script which can delete a few lines from a file which is currently being used by another process.

File gets appended using tee -a command due to which its size is getting increased. Contents like :

Code: [INFO] 25/09/2012 05:18 Run ID:56579677-1 My requirement is to remove lines which are more than 1 month old...

I have a data list, like

12345 23456 67891 -20000 200 600 20 ...

Assume the size of this data set (i.e. lines of file) is N. I want to randomly draw m lines from this data file. Therefore, the output should be two files, one is the file including these m lines of data, and the other one includes N-m lines of data.

Is there a way to do that using a Linux command?
