Login to remote machine pass commands and capture all in a file
Dear user/friends,
After a long gap of 6 years i am back to this forum to find a solution and i hope i will get a solution or atleast a workaround for the problem
Following is my task which i am trying for almost 3 days without any success.
1) run this command from my terminal (note i cannot change this command or alter)
2) This will login to remote machine with some banner messages it will ask me to select from list of free ports e.g.,
3) Now i need to pass any of these free port numbers i.e., 17 or 20 or 24 on remote terminal
Once port number is provided it will display the following:
4) now i need to pass
and press enter button
It will display the following (Similarly i need to pass the password and press enter)
5) Once password is provided it will display the following
6) now i need to provide my command e.g., runjob
Once the above command is provided it will run for some time lets say for 2 mins or 5 mins
once completed it will display
here i need to provide the command as:
(control key plus the closing square bracket)
then it will display following:
again i need to pass
and press Enter
I will be really thankful if someone can provide me how to solve this problem.

Please review the rules you agreed to when you joined this forum 6+ years ago. Use CODE tags whenever you post sample input, sample output, and code segments.

Reason: Change most Bold tags to CODE and ICODE tags.
If you could alter the command line, we could tell you how to provide a here-document to fill in the responses you want to send to the script on the remote server or we could tell you how to pipe input into your command to tell it how to provide the responses you want to send to the script on the remote server.
But, since you explicitly state that this command cannot be altered, all we can suggest is that you put this command in a script and then execute the script with standard input redirected from a source that provides the text you want to feed to the remote server while this command is running.
Another alternative would be to use an expect script, but again; not if you are unwilling to change that line of code.
Appreciate your quick response. currently what i am trying to do is:
following is the output i get

Also tried using expect but some mistake i am making
Output i get
Try just putting the following text in file.txt:
In other words, just put the exact text that you would type into your terminal in response to the prompts issued by the remote server. No echo, no double-quotes, no sleep unless you would type those commands to the remote server when you are running an interactive session with that server.
And, then run your command:
If you really want to preserve the output from previous runs and just tack the output from this run to the end of the output from previous runs, change the >out.log at the end of the script back to >>out.log.

Your out.log in post#3 contains telnet> \r" , which makes me suspicious. Make sure your input file does NOT contain DOS line terminators (<CR>, 0x0D, \r).
Hi RudiC
you are correct it was a copy paste error kindly ignore.
Trying to get help from my java colleague if he/she can help but i must say it should be pretty easy with shell.
