generate random passwords with a bash function
Posted by get on May 08 2022 13:40:18
as first we need to add this code to our .bash.rc 
# Generate a random password
# $1 = number of characters; defaults to 32
# $2 = include special characters; 1 = yes, 0 = no; defaults to 1
function randpass() {
 [ "$2" == "0" ] && CHAR="[:alnum:]" || CHAR="[:graph:]"
 cat /dev/urandom | tr -cd "$CHAR" | head -c ${1:-32}
 echo
}

Once you stored it and read into memory you will be able to generate pw like this:

# randpass 16 0
MkyzmsLYJVIom8B9
# randpass 32 1
g&^>K1:40Y*&R$C(o;q!XS1,2j^_WvRr

enjoy!
