View Full Version : how to get first n lines of a file
March 9th, 2007, 04:04 AM
i have some huge text files.
But while I test and develop, I want some small files.
So I want a way to "cat" the first n-lines to another file.
There must be some nice linux command tools for this.
Thanks in advance

You're welcome. For future reference, the apropos command is helpful when you know what you want to do, are sure some command does it, but aren't sure which one. Try this:
apropos first lines
And don't forget the forum search.

You could also do
sed -n 1,Np file.txt > newfile
That will put the first N lines in newfile.

head is a lot faster than sed, so... I am just babbling, I guess.
