Is there a way to count in Linux Terminal?

Solution

  • Use wc:

    wc -l <filename>

    This will output the number of lines in <filename>:

    $ wc -l /dir/file.txt
3272485 /dir/file.txt

    Or, to omit the <filename> from the result use wc -l < <filename>:

    $ wc -l < /dir/file.txt
3272485

    You can also pipe data to wc as well:

    $ cat /dir/file.txt | wc -l
3272485
$ curl yahoo.com --silent | wc -l
63
