Hi @jeesshnasree 

[susan@cyber ~] sudo for i in {1..5}; do echo "test $i"; done

-bash: syntax error near unexpected token `do'

You will encounter a syntax error because sudo expects a single command, not a complex shell construct like a for loop.

===================================================================================

vim test_script.sh ## Add the for loop code to the script: ##

#!/bin/bash

for i in {1..5}; do
echo "test $i"
done

chmod +x test_script.sh

sudo ./test_script.sh
test 1
test 2
test 3
test 4
test 5

OR

(The main point to remember is that you should use sudo for each command inside the loop, rather than trying to use it for the entire loop. Another good method is to put the loop in a script file and run that script with sudo.)

for i in {1..5}; do sudo echo "test $i"; done
