  • linux 常用命令: runuser

    rpm: coreutils-8.4-9.el6.x86_64

    runuser --help
    用法:runuser [选项]... [-] [用户 [参数]... ]
    Change the effective user id and group id to that of USER.  Only session PAM
    hooks are run, and there is no password prompt.  This command is useful only
    when run as the root user.  If run as a non-root user without privilege
    to set user ID, the command will fail as the binary is not setuid.
    As runuser doesn't run auth and account PAM hooks, it runs with lower overhead
    than su.
    
      -, -l, --login               make the shell a login shell, uses runuser-l
                                   PAM file instead of default one
      -g --group=group             specify the primary group
      -G --supp-group=group        specify a supplemental group
      -c, --command=COMMAND        pass a single COMMAND to the shell with -c
      --session-command=COMMAND    pass a single COMMAND to the shell with -c
                                   and do not create a new session
      -f, --fast                   pass -f to the shell (for csh or tcsh)
      -m, --preserve-environment   do not reset environment variables
      -p                           same as -m
      -s, --shell=SHELL            run SHELL if /etc/shells allows it
          --help        显示此帮助信息并退出
          --version        显示版本信息并退出
    
    单独的"-"选项隐含了-l。如果不指定用户,则假设其为root。
