undelete supports the following options:
If the -l, -p, -s, -u and -v options are not specified, undelete recovers the specified files.
-l
print a listing of all versions of the specified file(s)
-p
purge (permanently delete) specified source file(s)
-s
turn the version attribute on for the specified directories and its subsequent child directories
-u
turn the version attribute off for the specified directories
-v
force the specified file(s) to be versioned
The following additional options are recognized:
-d
normally, if the specified file is a directory, undelete will operate on the files contained in that directory. If this option is specified, undelete operates on the directory itself.
--------------------------------------------------------------------------------
NOTE: undelete does not work on directories that are mounted.
--------------------------------------------------------------------------------
-i
undelete will prompt for confirmation prior to recovering a file that will overwrite the current version of the file. A y answer means that the undeletion should proceed. Any other answer prevents undelete from undeleting the file.
-f
undelete will recover the file(s) without prompting even if it is overwriting over an existing current version of the file. This option overrides the -i option. Note that this is the default if the standard input is not a terminal.
-r
undelete will operate recursively on any directories in the argument list. Symbolic links that are encountered with this option will not be traversed.
-m [+-]days
undelete will only consider files that were deleted less than ( - ), greater than ( + ) or exactly (neither - nor + ) days ago.
