Runs a timer for a specified duration. A progress meter is shown with details of:
- current time
- elapsed time in seconds
- remaining time in seconds
The output is presented at intervals on a single line.
Syntax: timer [-v|--verbose] INT # seconds
timer [-v|--verbose] INTs # seconds
timer [-v|--verbose] INTm # minutes
timer [-v|--verbose] INTh # hours
| Option | Description | Default |

Since the output appears on a single line this isn't exactly what you'll see but this is an idea of what the output looks like.
$ timer 10 # ten seconds

- The output columns are:
- First two columns: the current date and time
- Third column: graphic progress meter
- Fourth column: percentage of the total duration - this is a reflection of the progress meter but in numeric form instead of graphic
- Fifth column: current elapsed time in seconds
- Sixth column: current remaining time in seconds
- The script seems to be a little slow starting on some platforms. I'm not exactly sure what's going on but it's only delayed a couple of seconds. You should only notice it for very small durations such as five seconds.
