Open a file from within a Bourne shell Script
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 "/"`

ZGREP(1)                                                      General Commands Manual                                                     ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep  options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
