Command not found error while shell scripting

Question

I'm trying to execute the program as followed.

./chExt1.sh cpp test.CPP

This should rename test.CPP to test.cpp but I don't even think this script is executing at all.
I am consistently getting this "command not found error".
The script is below :

#!/bin/sh
newExtension=$1;
oldFile=$2;

        firstPart=`echo $oldFile | sed  's/\(.*\)\..*/\1/'`
    newName="$firstPart.$newExtension";

#echo $oldFile
#echo $newName
mv "$oldFile" "$newName"
#echo "$oldFile"
#echo "$firstPart"
#echo "$newName"

It is working to me on Ubuntu 12.0. What about your echo, do they show proper data when uncommented? — fedorqui

It worked in Fuduntu 2013.2. Do you have sed installed? What Linux OS are you using? — Chris Forrence

Have you tried sh chExt1.sh cpp test.CPP? Instead of ./chExt1.sh... — nullByteMe

I'mn using Ubuntu 12.04.1 LTS I haven't tried running with them uncommented but I'll check that out. — DiamonW

add -x to your #! line to output script execution to stdout. #!/bin/sh -x It really helps with troubleshooting..you can see what is going on while it executes. — Mike Gardner

I finally fixed the issue. Something went horribly wrong when I FTP'd the text file which contained the script and then just transferred it inside of a .sh in linux. I wrote in from scratch in emacs and that cleared everything up.

Based on your comment, do this in vi to remove the extra control characters. I have had this problem before when editing files in gedit or when editing in Windows and then using on a Unix/Linux machine.

To remove the ^M characters at the end of all lines in vi, use:

:%s/^V^M//g

The ^v is a CtrlV character and ^m is a CtrlM. When you type this, it will look like this:

:%s/^M//g

In UNIX, you can escape a control character by preceeding it with a CtrlV. The :%s is a basic search and replace command in vi. It tells vi to replace the regular expression between the first and second slashes (^M) with the text between the second and third slashes (nothing in this case). The g at the end directs vi to search and replace globally (all occurrences).

Is there an emacs equivalent of this? I haven't had to learn vi at all this semester so I have no idea how to use it.

If you don't know vi, then type vi filename at the command line, then type the command just as shown (colon and everything). Then to save, type SHIFT+Z+Z (do not press the + sign). Or you can type :wq!

It's saying that pattern ^M isn't found.
