Three POSIX-compliant shell functions that rely on no extra utilities outside
of standard base installs. shuff() is needed for some BSD systems where
shuffle(1) is used in place of shuf(1):
shuff () {
if [ $(command -v shuf) ]
then
shuf -n "$1"
elif [ $(command -v shuffle) ]
then
shuffle -f /dev/stdin -p "$1"
else
awk 'BEGIN{
"od -tu4 -N4 -A n /dev/urandom" | getline
srand(0+$0)
}
{print rand()"\t"$0}' | sort -n | cut -f 2 | head -n "$1"
fi
}
gen_monkey_pass () {
I=0
[ $(printf "$1" | grep -E '[0-9]+') ] && NUM="$1" || NUM="1"
until [ "$I" -eq "$NUM" ]
do
I=$((I+1))
LC_CTYPE=C strings /dev/urandom | grep -o '[a-hjkmnp-z2-9-]' | head -n 24 | paste -s -d \\0 /dev/stdin
done | column
}
gen_xkcd_pass () {
I=0
[ $(printf "$1" | grep -E '[0-9]+') ] && NUM="$1" || NUM="1"
[ $(uname) = "SunOS" ] && FILE="/usr/dict/words" || FILE="/usr/share/dict/words"
DICT=$(LC_CTYPE=C grep -E '^[a-zA-Z]{3,6}$' "$FILE")
until [ "$I" -eq "$NUM" ]
do
I=$((I+1))
printf "$DICT" | shuff 6 | paste -s -d '.' /dev/stdin
done | column
}
They can optionally take an argument on how many passwords to generate:
