Shell Code :#! /Bin/sh
 
The echo "test shell" error message is as follows:
Shell code: [root @ localhost test] #./test. sh
-Bash :. /test. sh:/bin/sh ^ M: bad interpreter: No such file or directory since I was not familiar with shell before, I learned about the source Committee after communicating with my colleagues, mainly because of test. sh is edited in windows and uploaded to linux for execution .. The sh file is in dos format. Linux can only execute scripts in unix format.
We can use the vi editor to view the file format. The procedure is as follows:
1. run the vi command to open the file.
Shell code: [root @ localhost test] # vi test. sh 2. use the: set ff command in the vi command mode.

The file format is dos.

3. modify the file format to unix
Method 1: Use vi to modify the file format
Command: set ff = unix

Run the set ff command to view the file format. The result is as follows:

Method 2: directly use the dos2unix command to modify
Shell code: [root @ localhost test] # dos2unix test. sh
Dos2unix: converting file test. sh to UNIX format... after modification, run./test. sh again. The execution is correct:
Shell code: [root @ localhost test] #./test. sh
Test shell
