I got the first part to work accepting the password and listing all the files in the current directory. The one I am having trouble is with "while" loop.

What command would I use to display that the user has entered the incorrect password and only having 3 tries to do it and then close the terminal.

Code:
PASS="lux"

read -p "Password: " mypassword

echo ""

if [ "$mypassword" = "$PASS" ] 

then

echo "Password Accepted" 

ls -l 

fi

NAME
radcrypt - generate password hash for use with radius, or validates a password hash SYNOPSIS
radcrypt [-d|--des] [-m|--md5] [-c|--check] plaintext_password [hashed_password] DESCRIPTION
radcrypt generates a hashed digest of a plaintext password, or can validate if a password hash matches a plaintext password. DES and MD5 hashes are currently supported. When generating a password hash a random salt is generated and applied. A hashed password can be validated by specifying -c or --check and passing hashed_password after plaintext_password on the command line. In this case hashed_password will be checked to see if it matches plaintext_password. If so "Password OK" will be printed and the exit sta- tus will be 1, otherwise "Password BAD" will be printed and exit status will be 0 (Note this is the opposite of a normal successful shell status). OPTIONS
-d --des Use a DES (Data Encryption Standard) hash (default). Ignored if performing a password check. -m --md5 Use a MD5 (Message Digest 5) hash. Ignored if performing a password check. -c --check Perform a validation check on a password hash to verify if it matches the plantext password. EXAMPLES
$ radcrypt foobar HaX0xn7Qy650Q $ radcrypt -c foobar HaX0xn7Qy650Q Password OK SEE ALSO
