Small count (Restricted shell)

If we need to restrict a Linux user to use only the commands we specify, we can use the restricted shell.

Use in a normal command environment:

Test: # bash-r # Enter the restricted shell# cd/bash:cd:restricted# exit

Specific settings:

# useradd test                 #  Add User # cd bin# ln -s bash rbash             #  Set Soft Connection # cd /home/test# vim .bash_profile     # .bash_profile        # Get  the aliases and functions    if [ -f ~/.bashrc ];  then            . ~/.bashrc     fi        # user specific environment and  startup programs         #PATH = $PATH: $HOME/bin      #  comment out the original path path     path= $HOME/.bin         export&nBsp path# mkdir .bin# ln -s /bin/ls .bin/# ln -s /bin/cat .bin/#  ln -s /bin/touch .bin/      #  assigning commands to users ## vim  /etc/passwd    test:x:502:502::/home/test:/bin/rbash         #  Modify Shell to Rbash    ## passwd test

To this configuration end, login test:

The test effect is still very obvious. What are the limitations of the shell with specific restrictions, with detailed instructions on the wiki:
