linux添加只读用户

useradd -s /bin/bash reader

这步不要指定rbash，否侧cd等內建命令无法使用

#3.修改用户密码

passwd test

#4.创建用户shell执行命令目录

mkdir /home/test/.bin

#5.root修改用户的shell配置文件

chown root. /home/reader/.bash_profile
chmod 755 /home/reader/.bash_profile

#6.修改bash配置文件，主要是指定PATH的读取

复制代码
vi /home/reader/.bash_profile

.bash_profile

#Get the aliases and functions

if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

#User specific environment and startup programs

#PATH=P A T H : PATH:PATH:HOME/bin
PATH=$HOME/.bin

export PATH

 

#切换到只读账号使环境变量生效
su - reader
source /home/reader/.bash_profile
复制代码

#7.将允许执行的命令链接到$HOME/.bin目录

复制代码

ln -s /usr/bin/tail /home/reader/.bin/tail
ln -s /bin/more /home/reader/.bin/more
