！＃/ bin / bash：没有这样的文件或目录

Question

First, I run

/bin/bash a.sh

It succeed.

But when I want to run

/bin/bash a.sh > a_info.txt

It failed.

Error: line 1: !#/bin/bash: No such file or directory

It does not seem that it's ' ^M ' that's causing this error.

Answer 1

The shebang pattern is #!/bin/your_shell , not !#/bin/your_shell . Just fix the typo.

Answer 2

Check the file's encoding.

If you get this error, but you did not misspell the 'shebang', have a close look at the file's encoding. I was getting this error on a file with encoding 'UTF8 with BOM'... I guess the BOM (Byte Order Mark) was causing the problem. Changed the encoding to ASCII and that fixed it (or you can use 'UTF-8 without BOM' which is effectively the same for files only containing ASCII characters).

Answer 3

如果您的shell脚本使用CRLF而不是LF行结尾，则“无此类文件或目录”错误的另一个可能原因是。
