SSH with progress bar?

But is there a way of seeing the progress of cp and mv commands on Linux servers (and ESXi) that you connect to via SSH clients (like Putty) ???

SSH is not a factor here in any way. Things like cp and mv don't have progress bars. SSH just shows you what the command does, SSH doesn't modify the commands in any way.

If you use SCP you can get a progress bar... or as @Romo mentioned, rsync with --progress.

That looks pretty slick.

While the appearance is a bit different - it appears to be much like the progress bar used in Chocolatey.org

You might be able to pipe into pv for a progress. I know it works with dd, so it might work with cp or mv.

I have never played with pv so don't know what it relies on or when it is likely to work or not.

pv is kinda a pain because you have to tell it how much data is moving.

That's why most things can't show progress bars because they don't know how much there is.

What works in some cases is to look at the target side for file operations. That depends a bit on the filesystem and doesn't work for thin provisioned files for example, but for a lot of other things. The watch-command will execute any given command ever N seconds, for example:

watch -n10 'ls -lsah /path/to/target'
watch -n30 'du -sh /path/to/target'
watch -n1 'df -sh | grep /mnt/point/of/the/target'

In some other cases, you can send specific tools a signal to report stats, for example

kill -USR1 PROCESSID_OF_RUNNING_DD_OPERATION
kill -USR1 PROCESSID_OF_RUNNING_CP_OPERATION
killall -USR1 rm

Replace USR1 with SIGINFO if you are on BSD or OSX. USR1 is specific to Linux, most other *nix are using SIGINFO.

This will also work with watch or a while-command-sleep loop (watch is basically doing the same in the background).

Quite a few long running operations will report back on USR1/SIGINFO. Check the manpages or just try it.

@thwr That does work, I've done it many a time.

I miss my

kill -HUP pid

Yeah, I like a dead OS
