Using watch with ssh

Question

I have the below commands which is running properly on the local machine.

watch -t -n1 "echo `date '+%Y-%m-%d %H:%M:%S'` | tee -a Time.txt" &>/dev/null &

But when I run it from the remote machine I won't create the expected output i.e. Time.txt is not created and will not be running as a background process.

ssh ipaddress watch -t -n1 "echo `date '+%Y-%m-%d %H:%M:%S'` | tee -a Time.txt" &>/dev/null &

Please help me on this. I have tried multiple options like putting ', " for watch command but it did not helped me out.

Answer 1

• No need to use echo to output the result of a sub shell.
• No need to use tee to append to a file.
• No need to use watch to sleep for one second.

Try this instead.

ssh -t ipaddress 'while sleep 1; do date +%Y-%m-%d\ %H:%M:%S >> Time.txt; done &'
