CentOS: $‘\r‘: command not found

1. Problems

When executing the script deploy.sh in CentOS, an error $'\r': command not found is reported.

Reason : The shell script is written under Windows and transferred to CentOS through tool software. However, the ending symbol of the Windows downlink is \r\n , and the end of the Linux downlink is \n . The two are different, so they cannot be recognized and need to be converted.

Two, solve

//执行sh  deploy.sh base，报错$'\r': command not found
sh  deploy.sh base

//1、dos2unix 脚本名，此处是dos2unix deploy.sh
//如果执行dos2unix deploy.sh报-bash:dos2unix:command not found，就使用yum install -y dos2unix 安装dos2unix
//如果执行成功，会报一个dos2unix: converting file deploy.sh to Unix format ...
dos2unix deploy.sh  

//2、安装dos2unix
yum install -y dos2unix

//3、再次执行dos2unix deploy.sh命令
//如果dos2unix deploy.sh执行成功，会报一个dos2unix: converting file deploy.sh to Unix format ...
//如果dos2unix deploy.sh执行成功后，再次执行sh  deploy.sh base还不行，依旧报 $'\r': command not found，就执行下面的sed命令


//4、sed -i 's/\r//' 脚本名
sed -i 's/\r//' deploy.sh

//5、再次执行sh  deploy.sh base
sh  deploy.sh base

After the above dos2unix deploy.sh and sed -i 's/\r//' deploy.sh are executed successfully, execute sh deploy.sh base again (here corresponds to the above 5, execute sh deploy.sh base again ) to start executing the script Commands, pull, build, running, create images and containers.
