cat line X to line Y on a huge file

Very simple issue but can't seem to find a simple resolution!

I have a massive text file from which I only need around 150 lines. The lines are really long and therefore viewing it in putty is a bit of a nightmare. I just want to copy these lines to another file so that I can view it properly in an editor. (I can't view the original file in an editor as my Windows machine can't handle it).

The lines I want start at around line 2000.

Thanks,

If you have xsel installed you could use sed with xsel. sed -n '2000,2150p' youfile| xsel –  McNisse Jan 18 '13 at 10:01
    
@McNisse Why do you need xsel? –  Bernhard Jan 18 '13 at 10:07
    
To copy the lines directly into the clipboard. –  McNisse Jan 18 '13 at 10:32

If bandwidth is not an issue, you can use editor or pager like more or less remotely. Remember to resize the PuTTY window to get some more context. –  peterph Jan 18 '13 at 10:59

I have an easy shell function for it (put in .bashrc), which uses sed

printLine () 
{ 
    sed -n -e "$1p" "$2"
}

You can easily use it by

$ printLine 2000,2250 file

I am using the function, because I always forget the correct sed-syntax.

You want to store the output in a different file, than it is easy:

$ printLine 2000,2250 file > output

I'm using ksh (should have mentioned that) and printLine doesn't work :S –  Rich Jan 18 '13 at 11:42
    
Sorted it... thanks to kev82 here - linuxquestions.org/questions/linux-software-2/… The following outputs lines 10 to 30... –  Rich Jan 18 '13 at 11:47

head -30 text.file | tail -20 > output.file –  Rich Jan 18 '13 at 11:50
    
@Rich ksh also supports functions, afaik, so you can probably easily port it. –  Bernhard Jan 18 '13 at 12:19

If you just look for a certain token, the grep command could be useful.

cat filename | grep pattern > extractedFilename

I don't think this really answers the question. Also, why are you using cat here? –  Bernhard Jan 18 '13 at 11:34
