help with creating a suitable config file
Hi, currently, my shell script hard codes several array variables (etc.
Code:
PEOPLE=(
Vincar
Matthew
)
 
FRUITS=(
Banana
Apple
Orange
Pineapple
)

I want to move these information into one config file and then in my shell script, parse the config file into the appropriate variables. Do you have any suggestions on how to do this? Thanks!

If you make your config file a shell script, your loading script could be as simple as source ~/.configfile

Gentoo actually does this for its system config files(/etc/conf.d/...) So does firehol. Very handy if you want to use its settings in your own scripts.

Code:
set -A

is another option.

Thanks, I don't know why this still isn't working though. Btw, I'm using bash.

For example, I have a file script.sh
Code:
echo PEOPLE: $PEOPLE
echo FRUITS: $FRUITS 
and a config.configfile
PEOPLE=(
Vincar
Matthew
)
FRUITS=(
Banana
Apple
Orange
Pineapple
)

when I run ./script.sh config.configfile, the output is
Code:
PEOPLE:
FRUITS:

the contents do not show...=(
thanks.

If ksh shell scripting make your config file

touch init.cfg

init.cfg:
Code:
#formulations properties (to shape without spaces and with separator "="
#
###########################################################################
#global parameters
###########################################################################
#
##### Variable PEOPLE
PEOPLE="Vincar Matthew"
#
##### Variable FRUITS
FRUITS="Banana Apple Orange Pineapple"

and your loading script could be as simple as ./init.cfg

is another option, but the shell she must be /usr/bin/ksh!

I don't see that you're actually loading the config file, it doesn't just happen unless you tell it. You have to do source config.configfile Which in your case might be source "$1" though you might want to check that "$1" exists and is a file and all that before you source it.

I don't think that's correct. You must source the script, not just run it, for the variables to end up in your current context and not a new one.
