Hey Rick... Morning dude! Thanks for the reply. I've tried a bunch of different combinations, including the one you posted.. What seems to be happening, is that I can get it to run. The tmp file is generated with the data but the session doesn't immeadiately detach. It only detaches after the pro

Hi Jakub So you're saying >>> ssh crawl_user@192.81.214.49 'screen -r "testname" -X "`ls -al >>> /crawl_tmp/* > aa.tmp`" ' is not the correct approach to running a remote cmd in a screen session, and that the cmd wrapped in the backticks is run on the local machine, not the remote machine???

Followup. So far lots of tests/no success: To refresh: The goal, to be able to reattach to a remote screen session, and to run a cmd in the remote screen session, and have the cmd return to the calling term Research/testing I should be able to create a remote screen session, and then reattach t

ssh/screen question - thread

Hey Ladies/Gents. This follows the other thread i posted over the last few weeks on devOPS stuff for managing groups of remote droplets/vms. My approach for now to implement clusterSSH as well as screen to be able to auto gen the remote droplets, and to be able to ssh into them to view status, as

Re: screen question?

Pipe commands to ssh similar to dd | ssh . This in turn could maybe be cron'd? Just a thought. Fred On Sep 22, 2016 1:49 PM, "bruce" wrote: > Hey guys. > > Trying to get my heads around something. I'm looking to automate a > process. Basically, I want to kick off/initiate a number of processes

screen question?

Hey guys. Trying to get my heads around something. I'm looking to automate a process. Basically, I want to kick off/initiate a number of processes on remote boxes. I've looked at different online sites, but I'm missing something.. I can ssh into the box, trivial. I know I can create a "screen" pr
