Hi. I remember asking earlier for rand48() related but could not get a
working solution. Afterwards I found it on my own.
Here are a few handy solutions.
Random password using rand48():
zmodload -i zsh/mathfunc
length=8 # Max possible value are equal to size of $chars.
chars="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!?:^~@#$%&*_+=[]/"
while (( i++ < length ))
do
random=$((1 + int(${(c)#chars} * rand48())))
password+="$chars[$random]"
chars[$random]=""
done
print "$password"
Random word from a string using rand48():
zmodload -i zsh/mathfunc
words="NIX Linux ZSH BASH PHP"
word=$((1 + int(${(w)#words} * rand48())))
print ${${words[*]}[(w)$word]}
---
The ran48()is significantly more random than bash/zsh $RANDOM built-in
Regards NiX
