Functions in a shell script
so i have a very big script that has the following format:

Code:
functionA () {

....
...
....

}

Results=$(functionA)

the code inside of functionA is very huge. so by the time the script gets to the "Results=" part, several seconds have already passed. the script is about 15MB in size.

how can i reorganize this so the script runs faster?

i didnt write this script but i have to make it run faster one way or another. any ideas?

i tried this:
Code:
....
...
.... | while read functionA
do
...
...
done

notice i got rid of the function and i just let the script run. the thought is to avoid making the script skip the huge functionA code and just have it run as soon as it is kicked off.

lr_environment

LR_ENVIRONMENT.IN(1)					  LogReport's Lire Documentation				      LR_ENVIRONMENT.IN(1)

NAME

       lr_environment - Export Lire configuration in shell script form

SYNOPSIS

       eval `lr_environment`

DESCRIPTION

       The lr_environment command is used to import the Lire configuration in Lire shell scripts.

       All of Lire configuration variables will be written in a format that can be evaled by the shell.

       Shell scripts don't usually have to use that command, since it is done by the defaults file sourced by each command.

       The old names used by when the configuration was done in shell script are also exported by this script for backward compatibility.
