linux 中，如何判断当前用户是否是root 呢？
判断当前用户是否是root
Shell代码
- #---------------------------- root user check ---------------------start
- if [ `id -u` -ne 0 ]; then
- echo "Please re-run ${this_file} as root."
- exit 1
- fi
- #---------------------------- root user check ---------------------end
- if [ x"$USER" = x"" ];then
- if id |grep "^uid=0(root)">/dev/null ;then
- :
- else
- echo "Please rerun `basename $0` as root ."
- exit 1
- fi
- else
- if [ ! x"$USER" = x"root" ];then
- echo "Please rerun `basename $0` as root ."
- exit 1
- fi
- fi
- #=============== check current user start ================
- if [ ! $USER = root ];then
- echo "Please rerun this script as root ."
- exit 1
- fi
- #=============== check current user end ================
- #!/bin/sh
- if id |grep "^uid=0(root)">/dev/null ;then
- echo is root
- else
- echo not root
- fi
- check_user(){
- if [ $UID -ne 0 ];then
- echo "Current user is not ROOT."
- echo "Please rerun the installer as Root user."
- exit 11
- fi
- }
