character in shell script

Question

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

$'
': command not found: line 2:

Please suggest a solution for the same.

Below are the intial lines used in the script,

#!/bin/sh

if [[ $# -lt 1 ]]; then
   echo "ERROR Environment argument missing <dev,test,qa,prod>"
   export RC=50
   exit $RC
fi

Answer 1

Your problem is that the file has Windows line endings. This can be caused by editing a file in Windows and trying to run it on a non-Windows system.

You can fix this problem using dos2unix to convert the line endings:

dos2unix ConstruedTermsXMLGenerator.sh

The corresponding utility to convert in the other direction is unix2dos.

Some systems have fromdos and todos.
