\r character in shell script

Question

I get the below error while trying to execute a shell script,

$\'\\r\': command not found: line 2:

Please suggest a solution for the same.

Answer 1

I had the same error and what I did was to transform the characters '\r' to '\n'. using this line:

tr '\r' '\n' < oldfile.sh > newfile.sh
mv newfile.sh oldfile.sh
chmod +x oldfile.sh
./oldfile.sh

I think you could also delete the '\r' characters by using:

tr -d '\r' < oldfile.sh > newfile.sh

tr is the command trasnform, and the -d is delete the following character.

I think the shell actually doesn't like '\r' character.
