chroot(1M) chroot(1M)
NAME
chroot - change root directory for a command
SYNOPSIS
/usr/sbin/chroot newroot command
DESCRIPTION
chroot causes the given command to be executed relative to the
new root. The meaning of any initial slashes (/) in the path
names is changed for the command and any of its child
processes to newroot . Furthermore, upon execution, the
initial working directory is newroot .
Notice, however, that if you redirect the output of the
command to a file:
chroot newroot command > x
will create the file x relative to the original root of the
command, not the new one.
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.
This command can be run only by a privileged user.
REFERENCES
cd(1), chroot(2)
NOTICES
One should exercise extreme caution when referencing device
files in the new root file system.
When using chroot, do not exec a command that uses shared
libraries. This will result in killing your process.
