Could someone help me to call a shell script with named parameters.
I mean

Callscript .sh -c someconfigfile.txt
or
callscript.sh -config someconfigfile.txt

inside the script how can I retrieve someconfigfile.txt using the parametername -c or -config.

Thanks.

You need to use getopts. Usually you can type man getopts to get some information, or search the web for examples.

Thank you. I could retrieve the parameter value using the piece of code below.

while getopts c: option
do
case $option in
c)
Config_File=$OPTARG
;;
esac
done

echo $Config_File
