chmod：无法访问'\\ r'：没有这样的文件或目录

Question

I have these 2 line in my aaa.sh file:

#!/bin/bash
chmod +x  /home/tot/*.html

When I run it on AWS EC2 Linux:

$ sh aaa.sh

I got this message:

chmod: cannot access ‘\r’: No such file or directory

Answer 1

You have Windows line endings in your file (\\r\\n). It needs to have Unix-style line endings (\\n only).

You can do the conversion with the common dos2unix utility, or the set ff=unix command in vim.

Answer 2

chmod shouldn't care about the contents of your files. I bet you have a file with a control character in the filename itself. Might display as a question mark, but ls -b *.html should show you the culprit. Are your sure you want executable html files?
