NAME
utmpdump - dump UTMP and WTMP files in raw format
SYNOPSIS
utmpdump [-froh] filename
DESCRIPTION
utmpdump is a simple program to dump UTMP and WTMP files in raw format, so they can be examined.
OPTIONS
-f output appended data as the file grows. -r reverse. Write back edited login information into utmp or wtmp files. -o use old libc5 format. -h usage information. 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 utmpdump -r < ascii file > wtmp but be warned as utmpdump was written for debugging purpose only.
BUGS
You may not use the option -r as the format for the utmp/wtmp files strongly depends on the input format. This tool was not written for normal use but for debugging.
