My question is mostly based on this
https://stackoverflow.com/questions/22479631/pipe-timely-commands-to-ssh?rq=1
I am following above question and I am able to connect to a server, like this:
mkfifo CMDs.txt
exec 7> CMDs.txt
then from another terminal I am connecting to server like this:
sshpass -p 'mypass' ssh -tt myuser@$IP < CMDs.txt
the session gets established, but it is not an interactive session (as it should be). But I am able to send commands to remote server by redirecting them to file descriptor 7 like:
echo "some command" >&7
echo "some more command" >&7
this works fine and shows the output in the other terminal on which I initiated the session. My target is to send the commands, and capture the output of each command in a variable so that I can analyze it before sending another command. I think it should be possible by reading the stdout but I am not able to figure it out, hence posting the question. I am able to capture the output in a file by redirecting it in a file like this:
sshpass -p 'mypass' ssh -tt myuser@$IP < CMDs.txt >>outfile.txt
also as mentioned in the reference question, exec 7>&- should terminate the session, but it didn't, so how to terminate the session after I send all my commands?
