Use a different text editor. You have got a stray carriage return (`^M`) before the end of line character in the first line of the file (`#!/bin/sh`). Probably every line of the file has the same problem. — r3mainer, Jul 27 '16 at 22:35

The ^M in the error message tells all: your text file has been stored as 'DOS' text format, that is with CR+LF line endings. U*x interpreters take a LF (^J) character alone as a line terminator, so the superfluous CR (^M) character got appended to the /bin/sh shell declaration, thus making it invalid.

Save your file with Unix/Linux line endings (LF) or convert it with dos-to-unix converter before use.
