#!/bin/bash
zenity --entry --title="password dialog" --text="Enter your _password:" --hide-text

https://github.com/vgough/encfs/blob/master/encfs/encfs.pod wrote:--extpass=program
Specify an external program to use for getting the user password. When the external program is spawned, the environment variable "RootDir" will be set to contain the path to the root directory. The program should print the password to standard output.

EncFS takes everything returned from the program to be the password, except for a trailing newline (\n) which will be removed.

For example, specifying --extpass=/usr/lib/ssh/ssh-askpass will cause EncFS to use ssh's password prompt program.

Note: EncFS reads at most 2k of data from the password program, and it removes any trailing newline. Versions before 1.4.x accepted only 64 bytes of text.

-S, --stdinpass
Read password from standard input, without prompting. This may be useful for scripting encfs mounts.

Note that you should make sure the filesystem and mount points exist first. Otherwise encfs will prompt for the filesystem creation options, which may interfere with your script.
