[  This will need a bit of work to run under non-BSD.  It's also
   probably going to be the LAST safe-rm/unrm/whatever posting
   I approve, except for patches.  --r$  ]

This archives contains the sources for five programs (well, actually,
four, since one is a symbolic link):
    delete
    undelete
    expunge
    purge
    lsdel

The programs were written at Project Athena in response to the problem
which many novice Unix users have with accidentally deleting files
they didn't want to delete (Hell, I've done it :-).

I am already aware of quite a few improvements I could make in the
code (I am fairly certain that there are better regexp matching
libraries *and* better directory searching libraries I could be
using.), and I will be making them as soon as I am done with my
current project.  I would appreciate hearing any suggestions you may
have and/or accepting any patches you wish to submit :-)

X.TH EXPUNGE 1 "January 27, 1988" "MIT Project Athena"

X.SH NAME
Xexpunge, purge \- permanent removal of \fIdelete\fR\^d files
X.SH SYNOPSIS
X.B expunge
X[
X.B \-r
X] [
X.B \-i
X] [
X.B \-f
X] [
X.B \-t \fIn\fR
X] [
X.B \-n
X] [
X.B \-v
X] [
X.B \-l
X] [
X.B \-y
X] [
X.B \-\|\-
X] [ filename [ ... ]]
X.PP
X.B purge
X.PP
X.SH DESCRIPTION
X.I Expunge
Xand
X.I purge
Xpermanently remove files which have been marked for deletion using
X\fIdelete\fR(1).  Files removed with \fIexpunge\fR or \fIpurge\fR
Xcannot be recovered, and care should therefore be exercised in the
Xuse of these utilities.
X.PP
X.I Purge
Xis a simple utility which takes no command-line arguments.  When it is
Xexecuted, it searches through the user's entire home directory and
Xfinds all files that have been marked for deletion.  It then displays
Xa list of the files where are to be removed and prompts for
Xconfirmation.  A response from the user starting with the letter
X\fIy\fR will cause the files to be permanently expunged.
X.PP
XBecause
X.I purge
Xsearches through the user's entire home directory, it can take quite a
Xwhile to complete its search.  This is normal.
X.PP
XThe filenames passed to
X.I expunge
Xon the command-line can be directories (deleted or not deleted) or
Xdeleted files.  Deleted files or directories are always completely
Xexpunged, while the treatment of non-deleted directories depends on
Xthe
X.BR \-r
Xcommand-line option (see below).  If no command-line filenames are
Xspecified,
X.I expunge
Xdefaults to the current working directory.
X.PP
XFor information about wildcard use with \fIexpunge\fR, please see
X\fIundelete\fR(1).
X.PP
X.SH OPTIONS
X.I Expunge
Xaccepts the following command-line options:
X.TP
X.B \-r
XWhen a non-deleted directory is passed to \fIexpunge\fR, the
X.BR \-r
Xoption causes the directory to be searced recursively for deleted
Xfiles.  If the recursive option is \fInot\fR specified, only the
Xdirect children of the non-deleted directory are examined.  A
Xrecursive search of a large directory can take quite a while.
X.TP
X.B \-i
XThe user is prompted for confirmation with the name of the file and
Xits size in kilobytes before each file or directory is
Xrestored.
X.TP
X.B \-f
XUsed in conjunction with the
X.BR \-l
Xoption, this option prevents
X.I expunge
Xfrom prompting for confirmation after listing all the files that are
Xtoo be deleted.  Furthermore, it prevents the printing of error
Xmessages.
X.TP
X.B \-t\fIn\fR
XSpecifies the minimum age (in days) of files to be expunged, measured
Xas the length of time since the last file modification.
X.TP
X.B \-n
XNo file expunges are performed.  Instead,
X.I expunge
Xprints to the standard output the files that it would expunge were the
X.BR \-n
Xoption not specified.
X.TP
X.B \-v
XCauses
X.I expunge
Xto report each file as it is expunged, as well as the size of the file
Xand a running total of the number of kilobytes expunged.
X.TP
X.B \-l
XCauses
X.I expunge
Xto list all found files before expunging them, similar to the actions
Xof
X.I purge.
X.TP
X.B \-y
XThe total number of kilobytes expunged is printed after
X.I expunge
Xis finished removing files.
X.TP
X.B \-\|\-
XTwo dashes indicate that all arguments following it are to be treated
Xas file names, even if they start with a dash.

X.SH NAME
Xlsdel \- list deleted files
X.SH SYNOPSIS
X.B lsdel
X[
X.B \-d
X] [
X.B \-r
X] [
X.B \-t \fIn\fR
X] [
X.B \-y

X.PP
X.SH DESCRIPTION
X.I Lsdel
Xlists files that have been marked for deletion by the \fIdelete\fR(1)
Xprogram.
X.PP
XFor information about using wildcards with \fIlsdel\fR, see
X\fIundelete\fR(1).
X.PP
XFilenames passed to \fIlsdel\fR can be directories (non-deleted or
Xdeleted) or deleted files.  If a non-deleted directory is specified,
Xlsdel lists the deleted contents of that directory.  If the
X.BR \-r
Xoption is specified, all non-deleted children of the directory will be
Xsearched recursively for deleted files.  If not command-line filenames
Xare specified,
X.I lsdel
Xdefaults to the current working directory.
X.PP
X.I Lsdel
Xrecursively lists deleted directories by default.  This can be
Xdisabled with the
X.BR \-d
Xoption, which causes directory names, rather than their contents, to
Xbe listed.
X.PP
XThe
X.BR \-t
Xoption allows the user to specify a minimum age, in days, of files to
Xlist.  Only files that have not been modified in \fIn\fR days or more
Xwill be listed.
X.PP
XThe
X.BR \-y
Xoption causes
X.I lsdel
Xto print the total amount of space taken up by all the files it lists.

X.PP
X.DESCRIPTION
X.I Undelete
Xrecovers files and directories that have been marked for permanent removal by
X\fIdelete\fR(1), but have not
Xyet been removed.
X.PP
XFilenames passed to
X.I undelete
Xcan be directories or deleted files.
XIf a directory that is not deleted is passed to
X.I undelete,
Xthen the deleted files or directories in it will be restored; if the
Xrecursive option is specified, then all deleted files or directories
Xin any of its children will be restored as well.
X.PP
XThe shell wildcards \fI*\fR and \fI?\fR are interpreted correctly by
X.I undelete.
XIt is possible to pass wildcards to the program without the wildcards
Xbeing intercepted by the shell by setting
X.I noglob
X(in \fIcsh\fR) or by quoting the wildcards.  To delete a file that
Xactually has a wildcard in its name, you must precede the quoted
Xwildcard with a quoted backslash.
X.PP
XIf no files are specified on the command line,
X.I undelete
Xgoes into interactive mode.  In interactive mode, the user is prompted
Xto enter files to be restored, one file per line.  Typing a carriage
Xreturn on an empty prompt line exits the program.
X.PP
XWildcards and quoting backslashes can be entered directly at the
Xprompt without any shell interference (which is the
Xmain reason there is an interactive mode).
X.SH OPTIONS
X.I Undelete
Xaccepts the following command-line options:
X.TP
X.B \-r
XIf a specified file is a directory, the directory and all of its
Xchildren are restored recursively.  If a specified file is a symbolic
Xlink to a directory, then the directory and its contents will be
Xrestored, not the symbolic link.
X.TP
X.B \-i
XThe user is prompted for confirmation before each file or directory is
Xrestored.  This is not the same as the interactive file name entry
Xmode which is automatically activated when no files are specified on
Xthe command line.
X.TP
X.B \-f
XPrevents
X.I undelete
Xfrom reporting errors.  Further, if an intact (undeleted) version of a
Xfile which is requested for undeletion exists, then
X.I undelete
Xwill not prompt for confirmation before overwriting the undeleted file
Xwith the recovered one.
X.TP
X.B \-v
XCauses
X.I undelete
Xto report each file as it is restored.  Also, causes an introductory
Xmessage to be printed when entering interactive mode.
X.TP
X.B \-n
XNo file recoveries are performed.  Instead,
X.I undelete
Xprints to the standard output the files that it would recover were the
X.B \-n
Xoption not specified.
X.TP
X.B \-R
XPrevents
X.I undelete
Xfrom restoring the contents of directories in any case.
X.TP
X.B \-\|\-
XTwo dashes indicate that all arguments following it are to be treated as file
Xnames, even if they start with a dash.
