Question

我有一个名为AddUsers.sh的bash脚本。脚本应该采用这样的一行：

john.mccarthy@caltech.edu;1927/09/04;sudo,visitor;/visitorData

并返回如下变量：

name=john
surname=mccarthy
bdate=1927/09/04    
uname=mccjoh
pass=1927
groups(array)=sudo, visitor
folder=/visitorData

当我运行脚本并为其提供所需的文本文件时，它告诉我＆＃39; groupadd＆＃39; ＆＃39; chgrp命令＆＃39; ＆＃39;搭配chmod＆＃39;和＆＃39; chage＆＃39;都是错误。有人能告诉我为什么/给我任何反馈意见吗？

提前感谢您的帮助。

您可以在具有完整路径地址的脚本中使用命令。并且您可以通过“which”命令提取其完整路径地址。例如，而不是使用“chmod”你可以使用“/ bin / chmod” 输入以查找完整路径： $ chmod

Linux命令无法在bash中运行
