Expect Script Return Value

问题 I'm including simple Expect commands within a bash script (I know I could be just writing a pure Expect script but I would like to get it to work from within bash). The script is below: #!/bin/bash OUTPUT=$(expect -c ' spawn ssh mihail911@blah.org expect "password:" send "dog\r" ') Upon ssh'ing to the above address, it will return something of the form mihail911's password: on the prompt so I think my expect line is valid. When I run this my script does not print anything. It does not even

问题 I realized a shell using expect/spawn and send commands to SCP files from a remote server which send automatically the password when it is needed. The script works fine on UNIX terminal. Nevertheless, I tried to use this script throough a C++ process. It has been called by system() or even popen() function without sucess. This error is returned: "ioctl(raw): I/O error" Someone could have any clue? This is my script: #!/bin/bash targetHost=$1 password=$2 sourceFile=$3 destRep=$4 expect -c "

问题 I am trying to figure out how expect working. AFAIK the expect script consists of "expect" and "send" statements. So for each approporiate "expect" statement which appears on screen the "send" statement is called. Also the command "interact" means that controlling is passed back to user and he is able to interact with the terminal. Correct me if I am wrong. Those two statements works like a charm. 1st: #!/usr/bin/expect spawn ssh -q localhost; # Handles following message: "Are you sure you

the following script "testssh.ksh" proves that ssh have some problems when we try to perform ssh from multiple machines on the same time in fact the target of this script is to verify the file test_file under /var/tmp in the Solaris server (10.10.18.6) , as all see in some ssh steps we can’t verify the existing of the test_file because ssh stuck or not activate from the expect background - this script perform 15 times ssh to Solaris server with IP - 10.10.18.6 on the same time in order to verify the file_test under /var/tmp in the server my question - how to improve the ssh process in order to

问题 Currently I am trying to write a ruby script to logging-in SSH Remote Server using "pty" & "expect" ruby library. and also try to create new rails app inside the remote system using that script. Anyone can tell me. how logging-in to remote server using the ruby library ? 回答1: You should look at some of the examples for Net::SSH , it basically opens a connection and gives you a block to execute whatever command you like, e.g.: #!/usr/bin/env ruby require 'rubygems' require 'net/ssh' HOST =

问题 This is sort of a clunky question as I can't figure out a good way to describe it, but in expect you can do something like this: interact { \001 {do_something} \003 {do_something_else} "?" { set timeout 1 expect_user { "?" {send "?"} timeout {send_user "show a menu of the things you can do"} } stty raw -echo set timeout 60 } \035 {send "^]" send "quit\r" send_user "\n" exit } } which would create an interactive session where the user could go about business as usual, but upon pressing

问题 I'm running a script on a remote server like using this command: ssh root@host 'bash -s' < script.sh Now I'm trying to use expect to handle the password prompt. This is the script: #!/usr/bin/expect set cmd [lindex $argv 0] spawn -noecho ssh root@host $cmd expect { "password:" { send "password\r" } } If I run the script, it gives no output: ./ssh.exp 'bash -s' < script.sh I know that's not the way to use ssh without password, but this is not the question right here. UPDATE I tried the idea of
