Shell Programming and Scripting

I am suppose to make a program that cuts the extension off of a file. It uses that .ext to decide which program needs to be used to open the file. This only finds the name of the program from a list of programs I made. My problem is when it has the name of the program it needs to use, how can I make the program open the file with code in the script.

It is okay to assume that files will only have one period.

Code so far:

Code:

#!/usr/bin/bash -x

FNAME=$1
export FNAME
FILE_EXTENSION=`echo $FNAME | cut -f2 -d "."`

a=`grep  $FILE_EXTENSION dorc.sh`
echo $a
PROG=`echo $a | cut  -f5 -d "/"`

Yeah, sorry I tried to delete the other one, but there isn't a delete option. I thought that the post was more relevant to shell forum after I posted in that other one.

Ok - I move it there then. If you have any issues like this, contact a moderator please. I will remove the warning/reminder for the double post.
Ah I see I missed to close this thread and you got an answer in the other one, nvm. Setting a link to the other one and closing this here.
