[SOLVED] Reading a config file from a shell script

Issue

I am looking for a shell script analog to something like Pythons's ConfigParser or Perl's Config::INI. I have sourced files in the past to accomplish this, but I'd prefer to read rather than execute my "config file". Does anyone know of anything comparable to the above modules available for shell (or bash) scripts?

Solution

You don't want source it, so you should:

1.read the config, 2.verify lines 3.eval them

CONFIGFILE="/path/to/config"
echo "=$ADMIN= =$TODO= =$FILE=" #these variables are not defined here
eval $(sed '/:/!d;/^ *#/d;s/:/ /;' < "$CONFIGFILE" | while read -r key val
do
    #verify here
    #...
    str="$key='$val'"
    echo "$str"
done)
echo =$ADMIN= =$TODO= =$FILE= #here are defined

sample of config file

ADMIN: root
TODO: delete

var=badly_formtatted_line_without_colon

#comment
FILE: /path/to/file

if you run the above sample should get (not tested):

== == ==
=root= =delete= =/path/to/file=

sure this is not the best solution - maybe someone post a nicer one.
