Well the script needs to be POSIX so no sub-second sleep times. Also having a minimum time of 1 second while acceptable is not ideal, often it's done in as little as 75 ms.
It would be fine though to split the 'ipAdd' command up, after all its the url download which needs to timeout, the grep and uniq part will be lightening quick.
Code:
ipAdd=$($urlDownloaderProg "$url")
# Do this bit later: grep -Eo "$grepExpr" | uniq
Would that help? Or is it the assignment within the $() notation which is the problem rather than the piping?
PS. Does anyone know why both curl and wget don't seem to have a reliable "max time for whole operation"?
PPS. I know neither curl nor wget are POSIX - but they are the only bit of the script that isn't, and I've got to access the web urls somehow.

perl -pe 's/(\|333\}.*)\}$/$1|1.6}/' FIA.txt
This will search for the number 333 and appends 1.6 at the end of that line....... (1 Reply)
