I had this problem, turns out editing a bash script using Notepad++ was adding DOS line endings instead of UNIX line endings. Running the script in a Linux environment was causing the 'command not found' error to be thrown.

Managed to diagnose the problem by running my script like so:

bash -x testscript.sh

Which will dump any compiler output. The error message that gets thrown is:

bash -x testscript.sh
+ $'\r'
: command not found 2:
'estscript.sh: line 3: syntax error near unexpected token `{

I fixed the issue by changing the formatting of line endings in Notepad++ to be UNIX not DOS by going Edit -> EOL Conversion -> UNIX.
