I searched thru the web but did not get any examples.

We have the following documentation for using && and || for if-then-else condition
Code:
# cmd1 && cmd2   Run cmd1, then if cmd1 successful run cmd2, otherwise skip.
# cmd1 || cmd2   Run cmd1, then if cmd1 not successful run cmd2, otherwise skip.

However what do you do if you want to have multiple commands for "cmd2" to be executed with one of them being "exit" command.

What i want is - if there is a mutex file like /tmp/.test or /tmp/.globallock, the script should exit.
Can't see the point of the array. My interpretation of what you mean is:
Code:
#!/bin/sh
for filename in "/tmp/.test" "/tmp/.globallock"
do
if [ -e "${filename}" ]
then
          echo "Mutex file found: ${filename}"
          exit 1
fi
echo "After for loop"

Hmm. This is only subtly different from my post a fortnight ago ... but simplified a bit more.
