I have a problem with serial tty connected to etherlite devices. These ttys, any moment, generate many wtmp entries, making wtmp grows fast. I have not discovered the etherlite problem, and now I am thinking of filtering wtmp with fwtmp. I need to remove this "almost duplicated" lines, since there is just one,two or three seconds between each register of the same tty, same session. So I need a routine (shell, Perl, Python, awk, etc) to help to remove these supposed erroneuos (etherlite generated) lines in a routine which will run batch 23:50 by cron. Need to keep the start login line information and the final login line information for each session, removing these "quickly repeated" intermediated lines. Attached, a example print screen and full wtmp file generated by the command /usr/sbin/acct/fwtmp </var/adm/wtmp.
