- RECOVER(1) Minix Programmer's Manual RECOVER(1)
- NAME
- recover - recover files that have been removed.
- SYNOPSIS
- recover file ...
- EXAMPLES
- rm x; recover x # Unremove x
- recover a b c # Recover three files
- DESCRIPTION
- MINIX allows files that have been deleted (e.g., with rm) to be restored
- (in /tmp). The trick is that when a file is unlinked, its i-node number
- is kept in the directory entry. As long as the directory entry and disk
- blocks are not reused, the file can be recovered. This program is
- actually just a little front end for de, which must be installed as a
- set-uid root executable.
- SEE ALSO
- de(9).
