How to run scripts within a telnet session?
I want to connect to a remote host using telnet
there is no username/password verification
just
Code:
    telnet remotehost

then I need to input some commands for initialization

and then I need to repeat the following commands:
Code:
    cmd argument

argument is read from a local file, in this file there are many lines, each line is a argument
and after runing one "cmd argument", the remote host will output some results
it may output a line with string "OK"
or output many lines, one of which is with string "ERROR"
and I need to do something according to the results.

basically, the script is like:
Code:
    initialization_cmd  #some initial comands
    while read line
    do    
      cmd $line
      #here the remote host will output results, how can I put the results into a variable?
      # here I want to judge the results, like
      if $results contain "OK";then
           echo $line >>good_result_log
      else
           echo $line >> bad_result_log
      fi     
    done < local_file
    
     the good_result_log and bad_result_log are local files

is it possible or not? thanks!
