.sh Script not running on AWS EC2

Siraj Syed asked:

I downloaded a .sh file from S3 Bucket using the command

 /usr/local/bin/aws s3 cp s3://mm-s3-encrypt/AppD.sh /prod/msp/domains/dynamicapp_domains/

I do see it in the path,
I do a

chmod u+x AppD.sh

then ,


Result of this

My answer:

You edited your shell script with a Windows text editor (never, ever do this if you value your sanity) and as a result it has carriage returns at the end of every line. These are not treated specially by UNIX-like operating systems.

To fix the file, run dos2unix on it.

dos2unix AppD.sh
