NAME

chroot − change root directory for a command

SYNOPSIS

chroot newroot command

DESCRIPTION

The given command 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.

Notice that:

chroot newroot command >x

will create the file x relative to the original root, not the new one. 

This command is restricted to the super-user. 

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. 

SEE ALSO

chdir(2). 

BUGS

One should exercise extreme caution when referencing special files in the new root file system.
