chroot(8)
Name
chroot − change root directory for a command
Syntax
/usr/bin/chroot newroot command
Description
The chroot program is executed relative to the new root. The meaning of any initial slashes (/) in path names is changed for a command and any of its children to newroot. Furthermore, the initial working directory is newroot.
The new root path name is always relative to the current root: even if a chroot is currently in effect, the newroot argument is relative to the current root of the running process.
Restrictions
This program is restricted to processes with appropriate privileges.
Use extreme caution when referencing special files in the new root file system.
Examples
The following example will create the file x relative to the original root, not the new one.
% chroot newroot command >x
