timer

Purpose

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

Syntax: timer [-v|--verbose] INT # seconds
        timer [-v|--verbose] INTs # seconds
        timer [-v|--verbose] INTm # minutes
        timer [-v|--verbose] INTh # hours

Options and arguments

| Option | Description | Default | | —— | ———– | ——- | | -v | Enable verbose debugging | Debugging is not enabled |

Example

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

Notes

• 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.
