batch change all user passwords linux console

Tum kullanicilarin parolalarini toplu halde degistirmek icin hos bir script.

Isim acele oldugundan scripti duzenlemeye vakit ayiramadim oldugu gibi kullandim.

mesela uid i 1000 ve yuksek olanlari listelemesi gereken awk satiri calismiyor adam gibi.

vaktim olunca bakarim bir ara 🙂

orjinal scriptin random password generatoru baska birseyler istediginden onu degistirdim vs vs..

# /root is good place to store clear text password
FILE="/root/batch.passwd"

# get all non-root user account
# By default on most linux non-root uid starts
# from 1000

USERS=$(awk -F: ‘{ if ( $1 >1000 ) print $1}’ /etc/passwd)

# create file with random password
echo “Generating file, please wait…”

# overwrite file
>$FILE

for u in $USERS
do
p=$(dd if=/dev/urandom count=200 bs=1 2>/dev/null|tr “\n” ” “|sed ‘s/[^a-zA-Z0-9]//g’|cut -c-8) # create random password
echo “$u:$p” >> $FILE # save USERNAME:PASSWORD pair
done
echo “”
echo “Random password and username list stored in $FILE file”
echo “Review $FILE file, once satisfied execute command: ”
echo “chpasswd < $FILE”

# Uncomment following line if you want immediately update all users password,
# be careful with this option, it is recommended that you review $FILE first
# chpasswd < $FILE
sonra

sonra ver gazi.

chpasswd < batch.passwd
