-i, --item

You can choose the number to generate. Default is 1.

$ gpwd -i 10
mWXAiASq
b--ZtW7i
8f97Tdkq
cV5E4FmJ
siHQChPA
4PTESsAV
FpVbMzLc
0FIDaI53
vDJJ.cxU
ahQ3n7XV

-s, --strength

You can choose the strength of the password in "god", "strong", "normal", "weak". Default is "strong".

$ gpwd -s weak -l 16
ttexfrokswnjeiqa

$ gpwd -s normal -l 16
X5CmbohiboF0fnD7

$ gpwd -s strong -l 16
ok3Rh.wEt7IO_QMv

$ gpwd -s god -l 16
%"Eo1.Y0)ZfQ)>~0

mode	base string
weak	abcdefghijklmnopqrstuvwxyz
normal	weak + ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789
strong	normal + .-_
god	strong + +/!\"#$%&'()*,;<=>?@[]^{|}~`

You can also specify the character type directly.(v1.1.0 later)

mode	base string
num	01234567890
char1	.-_
char2	+/!\"#$%&'()*,;<=>?@[]^{|}~`
alpha	abcdefghijklmnopqrstuvwxyz
ALPHA	ABCDEFGHIJKLMNOPQRSTUVWXYZ
alnum	alpha + num
ALnum	ALPHA + num
Alnum	ALPHA + alpha + num
base64	ALPHA + alpha + num + /+=

-b, --base

You can specify the character type used for the password. (v1.2.0 later)

example is like Binary, Hexadecimal and Morse code.

$ gpwd -b "01"
10100010

$ gpwd -b "0123456789ABCDEF"
9672AE1C

$ gpwd -b ".-_"
.--.._..

Higher priority than -s,--strength option

$ gpwd -s god -b "01"
01101110

$ gpwd --seed 12345
0V2J5i8A

$ gpwd --seed 12345
0V2J5i8A

• Only integers

• --secure option is ignored

You can save frequently used options.(v1.4.0 later)

$ cat ~/.gpwd.json
{
  "length": 16,
  "strength": "god",
  "secure": true
}
