Hello everone.

I have an issue when running last command in my hp-ux system:

#last
Invalid record size. Unable to continue ...

OS Version: B.11.23

Hi Dennis,

Thank you for your reply.

The contents of the file are not important.

I ran the following to scratch the file:

#echo > /var/adm/wtmp

Then:

#last
Invalid record size. Unable to continue ...

#ls -ltr /var/adm/wtmp
-rwxrwxr-x 1 adm adm 1 Jul 6 09:19 /var/adm/wtmp

#file /var/adm/wtmp
/var/adm/wtmp: commands text

same issue still exist.

Should you not be clearing down the wtmps file, not wtmp?

> /var/adm/wtmps

It works now.

Thank you Duncan, and Dennis.

Ack! You should not be using echo, that's an example of how the file gets corrupted.
