Linux last login get the logins yesterday and email it the next day or specific time via crontab

I need to know the last login yesterday and email it to me via crontab....

Since the last command shows all the login you need to scroll up. Using grep and cut might do the trick.

cron login last

  1. Create a script for yesterday.. yesterday.sh

    #Get the date month and date cut the necessary date

    ystd=$(date --date yesterday | cut -d' ' -f2,3) tdy=$(date --date today | cut -d' ' -f2,3)

    #show the date yesterday Month and date

    echo ${ystd} #show the date today Month and date echo ${tdy}

    #grep the date try checking the tdy since you may have no login yesterday

    last | grep "$tdy"

    email it
