sleepenh – enhanced sleep program

Last Updated on January 22, 2022

sleepenh is a program that can be used when there is a need to execute some functions periodically in a shell script.

It was not designed to be accurate for a single sleep, but to be accurate in a sequence of consecutive sleeps.

After a successful execution, it returns to stdout the timestamp it finished running, that can be used as INITIALTIME to a successive execution of sleepenh.

INITIALTIME is a real number in seconds, with microseconds resolution. This number is system dependent. In Linux systems, it’s the number of seconds since midnight 1970-01-01 GMT.

Features include:

• Designed for shell scripts that need to perform a loop that repeats at a regular time interval, without cumulative errors.
• Supports microsecond resolution.
• Specify the time you need between two calls of sleepenh.
