digizeph / create_users.sh
Created April 21, 2015 00:15
Copy two columns from the Google Sheet, users and key. Then replace all the '\t' with '='. Name it as credentials.txt. Run this script. It should create the users for you.
#!/bin/bash
while IFS='=' read USER KEY
do
if [ ! -d "/home/$USER" ]; then
sudo useradd -m $USER -g snal
echo created user $USER
sudo su - $USER -c "mkdir /home/$USER/.ssh; echo $KEY > /home/$USER/.ssh/authorized_keys; chmod 600 /home/$USER/.ssh/authorized_keys"
else
echo $USER already created

Question: write a script to check who has logged in into your machine in the past month and log this information (usernames and last login) to a file.
#!/bin/bash
onemonth=`date --date="1 month ago" +"%y%m%d"`
last -F -R| head -n -2| cut -c1-9,27-46 | grep -v "reboot"| while read line; do date=`date -d "$(echo $line | awk '{ print $2" "$3" "$4" "$5 }')" +"%y%m%d"`; [[ $date -ge "$onemonth" ]] && echo $line; done > output.txt
