SHELL SCRIPT TO REDIECT ALL STDOUT FROM SUBSHELL.

Here is a simple interactive shell script to redirect all stdout from the subshell.For example if the user wants to 

redirect contents of files entered to the file in temporary folder /tmp/sh, it can be done as follows :


Vim Script_Name.sh
:i
#!bin/bash
echo -n "Enter the file whose content is to be redirected using subshell: "

read file_path 

#enter the path of the file whose data is to be redirected.Multiple files can be given.

(

cat $file_path

)>/tmp/sh 

#The data is redirected to temporary folder.
:wq

The above script can be executed directly as follows:
# bash Script_Name.sh
  OR
#  sh Script_Name.sh

The script can also be executed  by giving execute permission as follows:
# chmod +x Script_Name
# ./Script_Name
