The chroot keyword[edit | edit source]

chroot works like the same system call on UNIX, by changing root directory for all pathnames that start with a / and all of its children to FILENAME. This system call can only be run by the superuser. Without FILENAME, the contents of $_ are used.

Syntax[edit | edit source]

  chroot FILENAME

Examples[edit | edit source]

  chroot $filename;
  chroot /usr
