EXAMPLES

Here is the 4 lines 'error.log' file.

    2014/06/27 08:43:00,not found
    2014/06/27 08:43:01,not found
    2014/06/27 08:43:02,not found
    2014/06/27 08:43:03,no auth

Then you execute the edge command.

    $ edge error.log
    1: 2014/06/27 08:43:00,not found
    4: 2014/06/27 08:43:03,no auth

The first line and the last line are output with a line number.

The below command is the other example of edge with match condition.

    $ edge --grep found error.log
    1: 2014/06/27 08:43:00,not found
    3: 2014/06/27 08:43:02,not found

The above command is mostly same as below commands.

    $ cat error.log | grep found | head -n1
    $ cat error.log | grep found | tail -n1
    $ cat error.log | grep found | wc -l

You can get total line count too.

    $ edge -t --grep found error.log
    1: 2014/06/27 08:43:00,not found
    3: 2014/06/27 08:43:02,not found
    total: 4 lines
