atq2 - The improved atq command

Overview

atq2 allows you to view the scheduled commands in your 'at' queue (or atq). You can also filter by command, order by ID or timestamp and more.

I run a server that can have around 10,000 tasks scheduled using 'at'. The 'atq' command only displays the ID and the timestamp of the scheduled command which isn't as useful as it could be. In order to view the command associated with each ID you would need to then run 'at -c ID' but even then it will display a bunch of mostly irrelevant info. This tool allows me to quickly see the information that I need.

Install

Stick the atq2 file into your /usr/local/bin directory and make sure it's executable.

Options

Usage: atq2 [-c <num>] [-i | -t] [-n <num>]

Flags:
                -c)    Display X number of characters of scheduled command
                -i)    Order output by Job ID
                -t)    Order output by timestamp
                -n)    Display X number of lines

Example Usage

In this example, I order by timestamp, show the first 120 characters of the command and only display 5 rows.

$ atq2 -t -c 120 -n 5

Other Information

This script has been tested as far and wide as my Ubuntu 18.04 machine. I also wrote this in a very short space of time so it's likely to be ridiculously buggy. Please fork and contribute if you find any bugs.
