.TH chroot 1
.SH Name
chroot \- change root directory for a command
.SH Syntax
.B /usr/etc/chroot
.I "newroot command"
.SH Description
.NXr "root directory change"
.NXM "root directory" "chroot command"
The 
.PN chroot
command is executed
relative to the 
.IR "new root" .
The meaning of any initial slashes
.RB ( / )
in path names is changed for a command and any of its children to
.IR newroot .
Furthermore, the initial working directory is
.IR newroot .
.PP
The new root path name is always relative to the current root: even if a
.PN chroot
is currently in effect, the
.I newroot
argument is relative to the current root of the
running process.
.SH Restrictions
This command is restricted to the super-user.
.PP
Use extreme caution when referencing special files
in the new root file system.
.SH Examples
The following example will create the file
.B x
relative to the original root, not the new one.
.sp
.RS
