- .SH DESCRIPTION
- .PP
- MINIX allows files that have been deleted (e.g., with fIrmfR) to be
- restored (in fI/tmpfR).
- 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 fIdefR, which must be
- installed as a set-uid root executable.
- .SH "SEE ALSO"
- .BR de (9).
