runuser: Specify a shell for running instead of the default shell (also works for login).
$ runuser ${user} -s ${-bin-sh}
try on your machine
The runuser command is used to run a command as a specified user. In this case, ${user} is a placeholder for the name of the user.
The -s option specifies the shell to be used for running the command. ${-bin-sh} is a placeholder for the path to the preferred shell, such as /bin/sh. The -bin-sh is likely a typo, and it should be ${bin_sh} or ${/bin/sh} instead.
So, the command runuser ${user} -s ${-bin-sh} would run a command as the specified user, using the specified shell. However, since there is a typo in the placeholder for the shell path, it would result in an error.
