NAME
       sshpass - noninteractive ssh password provider

SYNOPSIS
       sshpass [-ffilename|-dnum|-ppassword|-e] [options] command arguments

DESCRIPTION
       This manual page documents the sshpass command.

       sshpass is a utility designed for running ssh using the mode referred to as "keyboard-interactive" password authentication, but in non-interactive mode.

       ssh uses direct TTY access to make sure that the password is indeed issued by an interactive keyboard user. Sshpass runs ssh in a dedicated tty, fooling
       it into thinking it is getting the password from an interactive user.

       The command to run is specified after sshpass' own options. Typically it will be "ssh" with arguments, but it can just as well be any other command. The
       password prompt used by ssh is, however, currently hardcoded into sshpass.

[root@yaowenxu Desktop]# sshpass
Usage: sshpass [-f|-d|-p|-e] [-hV] command parameters
   -f filename   Take password to use from file
   -d number     Use number as file descriptor for getting password
   -p password   Provide password as argument (security unwise)
   -e            Password is passed as env-var "SSHPASS"
   With no parameters - password will be taken from stdin

   -P prompt     Which string should sshpass search for to detect a password prompt
   -v            Be verbose about what you're doing
   -h            Show help (this screen)
   -V            Print version information
At most one of -f, -d, -p or -e should be used
