The undelete command is used to administer versioned files.
It allows you to recover (or undelete) a previously unlinked (or deleted)
file. undelete is the ability of
a filesystem to transparently maintain versions of a file,
and to restore a previous version of that file to be the current version.
For more information, see
``Retrieving deleted files'' in the Operating System User's Guide
``Versioning filesystems (undelete)'' in the System Administration Guide.
The files are a list of files with optional appended version
specifiers, consisting of a semicolon followed by a version
number. If no version specifier is specified, the newest
previous version is assumed.
Setting $SHOWVERSIONS to 1 in your environment allows all versions of
files to be shown when a directory is searched.
As with other special characters, the semicolon (;) symbol
has a special meaning to the shell and causes termination
unless quoted (that is, made to stand by itself). In this instance,
the semicolon should be quoted by
preceding it with a backslash (\). For example, file;2
is written as file\;2 to avoid premature termination.
undelete supports the following options:
If the -l, -p, -s, -u and -v options are not
specified, undelete recovers the specified files.
print a listing of all versions of the specified file(s)
purge (permanently delete) specified source file(s)
turn the version attribute on for the specified directories
and its subsequent child directories
turn the version attribute off for the specified directories
force the specified file(s) to be versioned
The following additional options are recognized:
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.
undelete does not work on directories that are mounted.
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.
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.
undelete will operate recursively on any directories in the
argument list. Symbolic links that are encountered with this option
will not be traversed.
undelete will only consider files that were deleted less than ( - ),
greater than ( + ) or exactly (neither - nor + ) days ago.
undelete does not work with special device files.
This example purges old versions of files to reduce undesirable
pollution of the filesystem. In this instance, all versions older than 2 days
are purged. You can add this to your crontab entry so it is performed regularly:
undelete -rpfm+2 /home
