windows下编写shell在linux运行会报错

syntax error near unexpected token &＃39;$&＃39;\r&＃39;&＃39;

原因如下&＃xff1a;

1. 因为你所处理的文件换行符是dos格式的”\r\n” &＃xff1b;

2. 可以使用cat -v 文件名 来查看换行符是否是&＃xff0c;如果是上述的&＃xff0c;则行结尾会是^m 需要转换成linux/unix格式的”\n”&＃xff1b;

3. 具体转换办法就是转换换行符 。

解决办法&＃xff1a;

运行命令&＃xff1a;sed &＃39;s/\r//&＃39; redis.sh > redis-install.sh

redis.sh 是原来的名称

redis-install.sh 是转换格式之后的名字

用法&＃xff1a;

sh redis-install.sh 4.0.10 &＃xff08;后面跟的是你需要的版本号&＃xff0c;需要什么版本就写什么版本&＃xff09;&＃xff0c;我这里安装的4.0.10
