Re: "last" command coredump

that may be fall into 2 cases

1. last binary is corrupt , using cksum compare with last in same HP-UX version.

2. wtmp is corrupt

Re: "last" command coredump

try by clearing the wtmp file.
#mv wtmp wtmp.maybebad
#>wtmp
#last

Re: "last" command coredump

to get the same informations read wtmp file like this:

the following will convert it to ASCII file
#/usr/sbin/acct/fwtmp < /var/adm/wtmp > /tmp/file
then you can either edit the file or read it.

Then you can convert it back to binary form:
##/usr/sbin/acct/fwtmp -ic < /tmp/file > /var/adm/wtmp
