How to use expect and send command in UNIX/Linux?
Hello Everyone,

I am executing a unix script which logs into 50+ servers (netapp servers) and runs some commands and captures output locally. Below is the code snippet. file1.txt has names of all the remote servers where I am logging in.

Code:
     #!/bin/ksh
     #!/usr/bin/expect
     touch ~/snapmirror_output.txt
     for i in `cat file1.txt`
     do
   /usr/bin/ssh username@$i snapmirror status > ~/snapmirror_status.txt; expect "password:" send "password\r";awk '{split($4,a,":"); if (a[1]>=24) print}' ~/snapmirror_status.txt >> ~/snapmirror_output.txt;rm -rf ~/snapmirror_status.txt
   done

All the remote servers have the same password for the user (username) which is used above. Although I am using expect and send commands in the script with the correct password but still the script is asking for password for each server when I am running the script. Please help. Thanks a lot.

Rahul

safe_finger

SAFE_FINGER(8)						     Linux Programmer's Manual						    SAFE_FINGER(8)

NAME

       safe_finger - finger client wrapper that protects against nasty stuff from finger servers

SYNOPSIS

       safe_finger [finger_options]

DESCRIPTION

       The  safe_finger  command  protects  against nasty stuff from finger servers. Use this program for automatic reverse finger probes from the
       tcp_wrapper (tcpd) , not the raw finger command. The safe_finger command makes sure that the finger client is not run with root privileges.
       It  also  runs  the finger client with a defined PATH environment.  safe_finger will also protect you from problems caused by the output of
       some finger servers. The problem: some programs may react to stuff in the first column. Other programs may get upset by thrash anywhere	on
       a  line.  File  systems may fill up as the finger server keeps sending data. Text editors may bomb out on extremely long lines.	The finger
       server may take forever because it is somehow wedged.  safe_finger takes care of all this badness.
