Hi Josh,
Having such strict rules about your passwords obviously reduces the
keyspace and makes them far less secure. Also for the really paranoid
$RANDOM in bash is a pseudo-random number generator that could
possibly be predicted - you should use a more secure random source.
Here is my attempt at the script you are looking for. I'm guessing you
wanted the middle of the password to be lower-case only? Anyway
shouldn't be too hard to modify if this is not what your after.
"""
#!/bin/bash
ULENGTH=1 # number of upper-case letters
LLENGTH=5 # number of lower-case letters
NUMLENGTH=2 # number of numbers
ULETTERS="ABCDEFGHIJKLMNOPQRSTUVWXYZ"
LLETTERS="abcdefghijklmnopqrstuvwxyz"
NUMBERS="123456789"
for (( i=0; i<$ULENGTH; i++ ))
do
PASS="$PASS${ULETTERS:$(($RANDOM%${#ULETTERS})):1}"
done
for (( i=0; i<$LLENGTH; i++ ))
do
PASS="$PASS${LLETTERS:$(($RANDOM%${#LLETTERS})):1}"
done
for (( i=0; i<$NUMLENGTH; i++ ))
do
PASS="$PASS${NUMBERS:$(($RANDOM%${#NUMBERS})):1}"
done
echo "$PASS"
exit
