Description-en: Sleep until a given date with subsecond resolution
sleepenh is a sleep program for shell scripts that need to
perform a loop that repeats at a regular time interval, without
cumulative errors.
.
It supports microsecond resolution.
.
You can also specify the time you need between two calls
of sleepenh.
.
Here follows an usage example to clarify its purpose. This
example sends 'A' to ttyS0 every 1.2 seconds.
#!/bin/sh
# does not wait (or wait 0), just to get initial timestamp
TIMESTAMP=$(sleepenh 0)
while true; do
# send the byte to ttyS0
echo -n "A" > /dev/ttyS0;
# wait until the required time
TIMESTAMP=$(sleepenh $TIMESTAMP 1.200);
done
.
For more details, please read the manpage.
