./password_gen.sh
The default password length is 36 characters and the default style includes A-Z, a-z, 0-9.
Both of those defaults are easy to tweak using the optional flags.
./password_gen.sh -h
./password_gen.sh --help
Minimum password length: 8
Maximum password length: 100
./password_gen.sh -l20 #Sets password length to 20 characters.
./password_gen.sh -l50 #Sets password length to 50 characters.
./password_gen.sh (Default. Letters A-za-z numbers 0-9 No symbols)
./password_gen.sh -sS (Symbols subset!@ *=#$%&, Letters and Numbers).
./password_gen.sh -sH (Hyphens every 4 characters, Letters and Numbers)
./password_gen.sh -sL (Letters only)
./password_gen.sh -sU (UPPERCASE LETTERS ONLY)
./password_gen.sh -sC (Comprehensive: all printable ASCII characters)
Any style that includes symbols will begin and end with a letter.
White space doesn't matter. These are equivalent:
"./password_gen.sh -s H" == "./password_gen.sh -sH"
Use both the -l flag and the -s flag to tailor your password.
Create password of length 40 with Style S:
./password_gen.sh -l40 -sS
Create password of length 30 with hyphens
./password_gen.sh -l30 -sH
Create password of length 50 using UPPERCASE LETTERS ONLY:
./password_gen.sh -l50 -sU
