Example: I log on my laptop machine (Ubuntu 14.04) via ssh and I need to make a .log file of some command output and than transfer it to my desktop machine. The command has -o option to redirect the output to a file. I could than just copy the file with scp command.

The question is: Can redirect the output directly to my machine, without the need to first make a file on laptop and than transfering it with scp?

Both machines use Ubuntu 14.

  • So... from Computer A you want to log into Computer B, and log output to Computer A? – Wilf May 20 '17 at 19:23

Depend on your command you can do something like this:

ssh user@machine command > log

the log will be saved in your machine, a real example:

ssh root@192.168.x.x ls > log

If your command does not supports outputs to stdout then run it like this:

ssh root@192.168.x.x "command -o output; cat output"  > log

    A slightly better way would be to use the tee command, so that you'd also see the output on the screen. For instance: ssh user@machine command | tee log – boardrider Aug 6 '19 at 17:21

If you want to see what are typing and output at the same time - try it:

ssh user@host 2>&1 | tee ssh-session.log
