$‘‘: command not found的解决方法 _Command

弱龄寄事外，委怀在琴书。这篇文章主要讲述$‘ ‘: command not found的解决方法相关的知识，希望能为你提供帮助。
缘起在Linux系统中，运行Shell脚本，出现了如下错误：

one-more.sh: line 1: $\\r: command not found

出现这样的错误，是因为Shell脚本在Windows系统编写时，每行结尾是\\r\\n，而在Linux系统中行每行结尾是\\n，所以在Linux系统中运行脚本时，会认为\\r是一个字符，导致运行错误。
解决方法去除Shell脚本的\\r字符：
方法1

sed -i s/\\r// one-more.sh

方法2

dos2unix one-more.sh

输出如下：

dos2unix: converting file one-more.sh to Unix format ...

如果出现如下错误：

-bash: dos2unix: command not found

说明dos2unix还没有安装，运行如下命令进行安装：

yum install -y dos2unix
