I'm looking for a bash command, which I can use to limit the number of lines of a file or another command output. E.g.

ls -thor | limit 10

would limit the output of the ls command to 10 lines (in the example, the command "limit" is naturally a imaginary command, whose equivalent I'm looking for). Is there such command, or a related solution?

Use head:

ls -l | head -n 15

10 lines is the default. Read the head man page for more options.

(older versions of head also support usage without the explicit -n as in head -15)

Thx. I should have figured it out, it's obvious when you know that there is a "tail" command.. :) –  simon Sep 11 '09 at 11:29

Syntax -integer is (at least in GNU version of head/tail discouraged - you should be using -n 15) –  user7385 Sep 11 '09 at 11:51
    
I didn't know that. Old habits die hard. I'll have to try to learn that. –  Doug Harris Sep 11 '09 at 13:49
    
The current GNU Coreutils version head accepts head -15 (but only if it's the first argument). The document describes this option as obsolete. –  Keith Thompson Jan 15 '12 at 16:20
