Parameters

Usage Examples

In the following you'll see a quick example of how to use the head command. Here is what our text file looks like:

in.txt:

            one
            two
            three
            four
            five
            six
            seven
            eight
            nine
            ten
            eleven
            twelve

To print the first 10 lines of in.txt run ./head.linux-amd64 < in.txt

The output is:

            one
            two
            three
            four
            five
            six
            seven
            eight
            nine
            ten

If you want to choose more than one file run ./head.linux-amd64 in.txt in2.txt in3.txt ...

To print e.g the first 5 lines use the -n parameter ./head.linux-amd64 -n 5 in.txt
