so i have a very big script that has the following format:
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:
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.
Simple shell script :
date
test_fn()
{
echo "function within test shell script "
}
on the shell prompt I run
> . test
Then I invoke the function on the command line as below :
test_fn()
It echos the line
function within test shell script
and works as expected.

Hi all,
I have a doubt..
If we create shell functions through a script itself, can we use the same functions in command line also..
for example:
$ cat a.sh
##### Functions
function system_info
{
}
function show_uptime
{
} (4 Replies)
so i noticed that when a shell script has a function defined in it, running "sh -x" on that shell script from the command line doesnt show what the function is doing. i like this.
is there anyway for anyone to get around that? to be able to see exactly what a function or functions are doing? (4 Replies)

service(8) System Manager's Manual service(8)NAME
service - run a System V init script
SYNOPSIS
service SCRIPT COMMAND [OPTIONS]
service --status-all
service --help | -h | --version
DESCRIPTION
service runs a System V init script in as predictable an environment as possible, removing most environment variables and with the current
working directory set to /.
The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT. The supported values of COMMAND depend on the
invoked script. service passes COMMAND and OPTIONS to the init script unmodified. All scripts should support at least the start and stop
commands. As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start com-
mand.
service --status-all runs all init scripts, in alphabetical order, with the status command.
EXIT CODES
service calls the init script and returns the status returned by it.
FILES
/etc/init.d
The directory containing System V init scripts.
ENVIRONMENT
LANG, TERM
The only environment variables passed to the init scripts.
SEE ALSO
/etc/init.d/skeleton,
update-rc.d(8),
init(8),
invoke-rc.d(8).
