# chrootuid(1)

run command in restricted environment

## NAME

chrootuid - run command in restricted environment

## SYNOPSIS

```
chrootuid newroot newuser command...
```

## DESCRIPTION

The **chrootuid** command sets up a restricted environment for executing *command*. Access to the file system is restricted to the *newroot* subtree; privileges are restricted to those of the *newuser* account (which must be a known account in the unrestricted environment). The initial working directory is changed to *newroot*.

**chrootuid** combines [chroot(8)](/chroot/8.md) and [su(1)](/su/1.md) into one program, so that there is no need to have commands such as /usr/bin/su in the restricted environment.

Only the superuser can use the **chrootuid** command.

## DIAGNOSTICS

The exit status is 1 when **chrootuid** has a problem, otherwise the exit status is the exit status of *command*.

## SEE ALSO

```
chroot(8), su(1)
```

## DIAGNOSTICS

Problems are reported to the syslog daemon.
