Some Person was login to your Linux VM? You have more than 10 people with a login to the System. In var/log/auth.log(Ubuntu) you see a fingerprint from ssh key.

cat ~/.ssh/authorized_keys | xargs -n1 -I% bash -c ‘ssh-keygen -l -f /dev/stdin <<<“%”‘

2048 32:3s:32:91:a2:f5:1c:3c:25:6e:05:f2:25:24:5b:01  person1@example.com (RSA)
4096 32:3s:32:91:a2:f5:1c:3c:25:6e:05:f2:25:24:5b:02 person2@example.com (DSA)
2048 32:3s:32:91:a2:f5:1c:3c:25:6e:05:f2:25:24:5b:03 person3@example.com (RSA)
4096 32:3s:32:91:a2:f5:1c:3c:25:6e:05:f2:25:24:5b:04 person4@example.com (RSA

Now you become a list with all Fingerprints and Name of your login users.

Find it out which person have login to your system….

grep “32:3s:32:91:a2:f5:1c:3c:25:6e:05:f2:25:24:5b:03” /var/log/auth.log

How to install jpegtran

apt-get install libjpeg-progs

Script found here

#!/usr/bin/env bash

function optimize
{
echo $1
filesize=`stat –format=%s “$1″`
if [[ $filesize -lt 10000 ]]; then
jpegtran -copy none -optimize “$1” > “$1.bak”
echo “pet”
else
jpegtran -copy none -progressive “$1” > “$1.bak”
echo “grand”
fi

if [[ $filesize -lt `stat –format=%s “$1.bak”` ]]; then
echo “compression plus lourde”
rm “$1.bak”
else
echo “good!”
mv “$1.bak” “$1”
fi
}
find . -name ‘*.jpg’ -type f -print0 |while read -d $’\0′ i; do optimize “$i”; done

Or you can use also image magic

find . -name ‘*.jpg’ -exec convert -strip -interlace Plane -quality 80 {} {} \;

Check if it is interlaced

find . -name ‘*.jpg’ | xargs identify -verbose *.jpg | grep Interlace
