Command not found error message when running script

Question

I'm learning how to make shell scripts in UNIX, but I keep coming across this stupid error. Let's say I make a script like this:

#!/bin/sh
echo HELLO

I save the file as test, and make the command executable by me with chmod 700 test. I save the file in my home directory, and (attempt) to run the file like so:

./test

Only for UNIX to reply back:

./test: Command not found.

What is going on? When I type out ls -l, there is an asterisk next to the file name. That wasn't there before I used the chmod command. Can anyone tell me what I'm doing wrong?

Answer 1

Make it executable:

chmod +x ./test

and make sure you save your file in Unix file format. And: check if your partition is executable (mount).

Answer 2

I had the same problem where I copied the file from Windows to Linux and tried to execute it. I did all suggestions above but nothing helped until I did a dos2unix on the file and that fixed it. It may not be the case for you, but just putting it out there
