Hello, I have a data file I'm searching. I know the line numbers that the data I want is in. I now want to extract only those lines in the file and output them to a new file. How do I do that using grep or awk. Thank you very much in advance.

You can use head and tail. To pull line 1000 tail -1000 filename | head -1 Sed will also let you match a line # http://www.gnu.org/manual/sed-3.02/html_chapter/sed_3.html#IDX25 grep with the -n will give you line numbers that you can then match as a starting pattern grep -n "." /etc/passwd | grep '^30:' | cut -f 2- -d ':' the above will use the '.' as a wild card matching all, the -n flag to grep will prepend line numbers. The '^30:' says give me line 30. The cut portion says to peel off the line number and present the balance.

Thanks David, You were a big help to me :)
