Create a bash script that permanently redirects the scripts output to a file. Once the output is permanently redirected execute 3 commands of your choosing within the script. Be sure that the script finishes by restoring output back to STDOUT
Homework Answers
ANSWER :
This is done using the exec command as you can see in the code below :
#!/bin/bash
exec 2<&1 # Save stdout in 2 as we need to restore it
exec 1>outfile # Permanent Redirection of output to
'outfile'
echo "Permanent redirection" #Command 1
ls # Command 2
pwd # Command 3
exec >&2 # Restore Output to STDOUT
The Bash Scripting is used to make a lot of manual work
