+.TH UTMPDUMP 1 "Februar 8, 2010" "" "Linux System Administrator's Manual"
+.SH NAME
+utmpdump \- dump UTMP and WTMP files in raw format
+.SH SYNOPSIS
+.B utmpdump
+.RB [ \-froh ]
+.I filename
+.SH DESCRIPTION
+\fButmpdump\fP is a simple program to dump UTMP and WTMP files
+in raw format, so they can be examined.
+.SH OPTIONS
+.IP \fB\-f\fP
+output appended data as the file grows.
+.IP "\fB\-r\fP"
+reverse. Write back edited login information into utmp or wtmp files.
+.IP \fB\-o\fP
+use old libc5 format.
+.IP \fB\-h\fP
+usage information.
+.PP
+utmpdump can be useful in cases of corrupted utmp or wtmp entries.
+It can dump out utmp/wtmp to an ASCII file, then that file can
+be edited to remove bogus entries and reintegrated, using
+.PP
+.sp 1
+.in +1c
+.nf
+\fButmpdump -r < ascii file > wtmp\fP
+.fi
+.in -1c
+.sp 1
+but be warned as
+.B utmpdump
+was written for debugging purpose only.
+.SH BUGS
+You may
+.B not
+use the option \fB\-r\fP as the format for the
+utmp/wtmp files strongly depends on the
+input format. This tool is
+.B not
+supported, use it at your own risk only.
