Wrapping 'sleep' with my 'resleep' function (Resettable sleep)
This is a very crude attempt in Bash at something that I needed but didn't seem to find in the 'sleep' command. However, I would like to be able to do it without the need for the temp file. Please go easy on me if this is already possible in some other way:
How many times have you used the 'sleep' command interactively only to realize that the amount of time you initially specified wasn't enough and you wanted to reset it? Or how many times have you had something sleeping for quite a while but you wanted to know where it was in the sleep countdown? I've found myself in these situations quite a few times when recording a TV show or some other multimedia. So I wrote the 'resleep' functions (which wrap around 'sleep') below which can then either be included in scripts where you'd normally use sleep by itself, or dotted into your environment and run as commands. It's not polished and I'm positive the logic isn't clean, but it's working for me so far. One thing I still need to add is the ability to pass a unit of time (in seconds, minutes, hours) to the wrapped 'sleep' command itself so that my "time units" count can be something other than one second as it is now. For example it would be nice to be able to set it to 30 minutes and then three time units would be 90 minutes. But that will come later... So here it is in all it's ugliness...
SCRIPT EDIT: Demoggified per cfajohnson's comments. Thanks!
As a sidenote, I couldn't think of a good way to do this without using the temp file, although I would have preferred to avoid it. The problem is being able to write to a variable while it's in use. Is there some way to do this without the temp file?
If I want a script to sleep for less than a second, would I use a decimal? In other words, if I wanted my script to sleep for 1/4 of a second, would I say, SLEEP .25 ?? (5 Replies)
Does anyone know a way to sleep less than 1 second?
Sometimes when I write scripts that iterates a loop many times it would be
nice to slow things down, but sometimes 1 second is too much. (9 Replies)

TIMETRANS(1p) User Contributed Perl Documentation TIMETRANS(1p)NAME
timetrans - Converts time into time
SYNOPSIS
timetrans [units-options] [-count]
DESCRIPTION
timetrans converts time from one type of unit to another. If any of the units options are specified, then timetrans will convert those
time units into the number of seconds to which they add up. If given the count option, timetrans will convert that number of seconds into
the appropriate number of weeks, days, hours, minutes, and seconds. The converted result is printed out. Units options cannot be
specified in the same execution as the count option, and vice versa.
timetrans is intended for use with DNSSEC-Tools, for calculating a zone's expiration time.
OPTIONS
Units Options
The converted value of each unit is totaled and a single result printed.
-seconds seconds
Count of seconds to convert to seconds.
-minutes minutes
Count of minutes to convert to seconds.
-hours hours
Count of hours to convert to seconds.
-days days
Count of days to convert to seconds.
-weeks weeks
Count of weeks to convert to seconds.
Count Option
The specified seconds count is converted to the appropriate number of weeks, days, hours, minutes, and seconds.
-count seconds
Count of seconds to convert to the appropriate set of units.
Other Options
timetrans has the following miscellaneous options.
-Version
Displays the version information for timetrans and the DNSSEC-Tools package.
EXAMPLES
Example 1: Converting 5 days into seconds
$(42)> timetrans -days 5
432000
Example 2: Converting 2 weeks into seconds
$(43)> timetrans -w 2
1209600
Example 3: Converting 8 days and 8 hours into seconds
$(44)> timetrans -d 8 -hours 8
720000
Example 4: Converting 1 week, 1 day, and 8 hours into seconds
$(46)> timetrans -w 1 -days 1 -h 8
720000
Example 5: Converting 14 weeks, 4 days, 21 hours, 8 minutes, and 8 seconds into seconds
$(47)> timetrans -w 14 -d 4 -h 21 -m 8 -s 8
8888888
Example 6: Converting 720000 seconds into time units
$(48)> timetrans -c 720000
1 week, 1 day, 8 hours
Example 7: Converting 1814421 seconds into time units
$(49)> timetrans -c 1814421
3 weeks, 21 seconds
Example 8: Converting 8888888 seconds into time units
$(50)> timetrans -c 8888888
14 weeks, 4 days, 21 hours, 8 minutes, 8 seconds
