Shell脚本出现$'\r': command not found

Centos7下执行shell脚本报错以下

[root@ip-172-29-10-16 ~]# sh install_zabbix_agent.sh 
install_zabbix_agent.sh: line 2: $'\r': command not found
install_zabbix_agent.sh: line 8: $'\r': command not found
install_zabbix_agent.sh: line 9: $'\r': command not found
install_zabbix_agent.sh: line 10: syntax error near unexpected token `$'{\r''
'nstall_zabbix_agent.sh: line 10: `install_zabbix(){

 

 

缘由

这是由于脚本文件可能在window弄过，有window下的空行，把他转换成unix格式的就行

 

解决办法

yum install dos2unix

 

而后再执行这个脚本就能够了
