linux的runuser命令

  Linux下runuser命令不太經(jīng)常用到,我們需要了解他的用法即可。下面由學(xué)習(xí)啦小編為大家整理了linux下runuser命令的相關(guān)知識(shí),希望對(duì)大家有幫助!

  linux的runuser命令詳解

  runuser --help

  用法:runuser [選項(xiàng)]... [-] [用戶 [參數(shù)]... ]

  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 顯示此幫助信息并退出

  --version 顯示版本信息并退出

  單獨(dú)的"-"選項(xiàng)隱含了-l。如果不指定用戶,則假設(shè)其為root。
