: Hello,
:
: I am trying to write a script that will collect output from a list of
: machines on my network.  To accomplish this I have setup ssh keys and have
: written a simple loop.  The only problem is my script does not go through
: the entire iteration of all the machines, just the first one it grabs during
: read.  Here is my code:
:
: #!/usr/local/bin/bash
:
:    cat machines.list |while read line ;
Useless Use of cat followed by a useless semi-colon
:    do
:        ssh -t myuserid@$line $1 >> /home/myuserid/output.txt
Stdin for the process is the pipe from cat.  SSH inherits stdin and
empties it.  use the -n option

while read line
   do
   ssh -n -t myuserid@$line $1
   done <machines.list >>~/output.txt
clear
less >>~/output.txt

Or you could pipe the results directly to less:
while read line
   do
   ssh -n -t myuserid@$line $1
   done <machines.list |less

:    done
:    clear
:    less /home/myuserid/output.txt
:
: The contents of machines.list is:
:
: proxy-01.mydomain.com
: proxy-02.mydomain.com
: proxy-03.mydomain.com
: proxy-04.mydomain.com
: proxy-05.mydomain.com
:
: When I run the script it grabs the output from the first machine in the list
: but goes no further.  What am I doing wrong here?
