runuser

Run commands as a specific user and group without asking for password (needs root privileges).

• Run command as a different user:

runuser {{user}} -c '{{command}}'

• Run command as a different user and group:

runuser {{user}} -g {{group}} -c '{{command}}'

• Start a login shell as a specific user:

runuser {{user}} -l

• Specify a shell for running instead of the default shell (also works for login):

runuser {{user}} -s {{/bin/sh}}

• Preserve the entire environment of root (only if --login is not specified):

runuser {{user}} --preserve-environment -c '{{command}}'
