What is [[: not found error?

I tried to execute a file containing a shell script.

I get an error called "[[: not found" error at the last line. How to resolve it?

You may find you stumble at other blocks later with POSIX shell related issues. People don't really understand how much bash actually provides until it's taken away. Take a look at this so you can hopefully avoid any other issues:

This interpreter:

#!/usr/bin/sh

Is either not bash or your file doesn't have the shebang in the right place.

ls -l /usr/bin/sh will tell you if it's a symlink to something other than bash.

If it is bash, then check that there's no leading characters before the #!.

[[ is bash. sh wants the [ variant.

Either change that to /usr/bin/bash (or wherever bash is located on your system), or adjust the expression accordingly:

if [ status_of_job -eq 0 ];

[ is actually an executable in linux. but [[ is not.

Try

if [ status_of_job -eq 0 ]; then

(note the single [] set).
