Script format of the--/bin/bash^m: there is no file or directory

The bash script under Linux does not support line breaks \r , and if you run a file that is copied from Windows, you /bin/bash^M: 坏的解释器: 没有那个文件或目录 may want to check if the file format is incorrect.

If this is a format problem, there are two ways:

First, find the replacement method

• First step: cat －A filename view ' \ 及 r \ 空白符， n \ 会显示为 r \ ，而 会显示为 ^m '.
• Step two: sed -i ‘s/\r$//‘filename replace all \r characters.

Ii. Vim Reset Document Format

• The first step: :set ff? look at the file format, you can see fileformat=dos such a hint.
• Second step: :set ff=unix cast to UNIX format.
• Step three: :wq Save the exit.

Then run again to see if the same error has occurred, and if it is still wrong, check the syntax and the related commands correctly.
