How can I prematurely break from a loop, or
a deliberately infinite loop for that matter,
while still don't exit the program?
I.e.,
#! /bin/zsh
while (true); do
# do computations
done
# when interrupted by the user,
# do a summary of the computations
# and output
# only then, exit program
The particular use case is yanked last.
Feel free to comment on the code as well, of
course!
The purpose is I stretch for ~1h every day
(e.g. today 1h 3m 55s) and use the below
functions to signal when too change position.
Only sometimes, I don't do the entire program,
say I stretch for ~30m or whatever instead.
With the output from the 'stretch' program,
when interrupted prematurely, I can do
$ echo $(s2hms $(( 28*65 )) )
30m 20s
and write it down it in my flipboard. That way,
digits won't lie :)
Only, I'd like to have this automated so
whenever 'stretch' is interrupted, last thing
it'll do is make the computation and output it.
Thanks in advance :)
