# go-edge

`go-edge` provides the command `edge` to show the edge of logs with conditional grep

## Usage

    $ edge [options] FILE

## Options

    -g   --grep  KEYWORD  grep condition

    -c                    also show the total line count

## Examples

Here is the 'error.log' file.

    $ cat error.log

    2023/02/27 08:43:00,not found

    2023/02/27 08:43:01,not found

    2023/02/27 08:43:02,not found

    2023/02/27 08:43:03,no auth

Then you execute the `edge` command. Then shown the first line and last line.

    $ edge error.log

    1: 2023/02/27 08:43:00,not found

    4: 2023/02/27 08:43:03,no auth

The number of top of line is line number of the file.

And you can use `-c` option to know total line number.

    $ edge -c error.log

    1: 2023/02/27 08:43:00,not found

    4: 2023/02/27 08:43:03,no auth

    total 4 lines

The above is pretty much the same as below command executions:

    $ cat error.log | head -n1

    $ cat error.log | tail -n1

    $ cat error.log | wc -l

With `--grep` option, you can get filtered 1st line and last line.

    $ edge --grep found error.log

    1: 2023/02/27 08:43:00,not found

    3: 2023/02/27 08:43:02,not found

With `--grep` and `-c` option:

    $ edge -c --grep found error.log

    1: 2023/02/27 08:43:00,not found

    3: 2023/02/27 08:43:02,not found

    total 4 lines
