The fact that you’re getting the funny output is a sure bet that your script has carriage return (CR) characters at the end of the lines, usually a symptom of using Windows editors that assume line endings should be CR/LF rather than just the standard UNIX LF (linefeed). That is causing error output like:

this_command_ends_hh<CR>: command not found

and because the CR is putting the cursor back at line start, it’s overwriting some of it:

this_command_ends_hh<CR>
: command not found

making:

: command not foundh

Examine your script with od -xcb scriptname to check for CR (displayed as \r) characters, you can also pipe the script output through od -xcb to see the real output. For example is a file I created with hello followed by a carriage return on the one and only line:

0000000    6568    6c6c    0d6f    000a
          h   e   l   l   o  \r  \n
        150 145 154 154 157 015 012
0000007

You can see the CR (\r) in there.

If that is the problem, simply remove the CR characters such as piping it through tr -d '\r'.

Executing cat hello.txt | tr -d '\r' | od -xcb shows that you can get rid of it:

0000000    6568    6c6c    0a6f
          h   e   l   l   o  \n
        150 145 154 154 157 012
0000006

In your case, assuming your script is called freak.bash, you would use:

tr -d '\r' <freak.bash >newfreak.bash

and newfreak.bash would be the one without the offending characters.
