Command or script to get user login details of last 6 months

  • 772

I need to get the details of the users logged in from last 6 months to analyze and to increase the cpu of my server. I'm tried the command last -a but it is not giving the complete results. Anyone please help me to get the details of users logged in from last 6 months.

Thanks in advance!

  1. Newer versions

    You can use -s option:

    last -s  -6month

    Display the state of logins since the specified time.

    use -t to specify until another date if you like.

    If you receive a message like:

    wtmp begins Tue Apr ...

    it means that "logrotate" has removed your log files so you don't have access to use them.

    for older versions you should specify full time:

    last -t 20170101000000
