Overview of users login in the past

[Canedje]

hello everybody.

Is there a method to show a list of users logged in at the RPI in the past including date and time?

I like to know this because my crontab commands where suddenly emptied without an explanation???
The header was stil there, the commands where gone.

Thanks for the answers

You could try the "last" command which will show you all the logins since the log file was last cleared. The usual man page will show you the available options.

After using last command I only see:

Code: Select all

wtmp begins Thu Jan  1 01:00:03 1970

It looks like this list is empty.
Do I need tot turn it on somhow before?

If I look to /var/log directory I do see:

Code: Select all

lrwxrwxrwx 1 root  root        9 dec  4 11:58 wtmp -> /dev/null

It looks like the wtmp file is ported to the /dev/null

What OS/distro are you running, because wtmp works on my Wheezy system that got upgraded to Jessie.
