Copy a file over SSH without SCP

Nice command for when you don't have scp available for whatever reason.

Works with binaries.

Alternatives

There are 2 alternatives - vote for the best!

Terminal - Alternatives
ssh HOST cat < LOCALFILE ">" REMOTEFILE
ssh username1@servername1 -t ssh username2@servername2 uuencode -m testfile1.tar - | uudecode > testfile1.tar

cat didn't seem to work with binaries to well for me, the above command seemed to do the trick.

Opps should be pointed out its going through a "hop" box (which is why I was searching here in first place), only need the last bit (after the -t) if doing it directly from one box to another...

uuencode -m <filename> <filename>

I have come across multiple situations where I could only get to a server from a very restrictive bounce point which would not allow file transfers. I was able to uuencode a file, copy the output to a text file over putty, and then uudecode the file to transfer it. This works with any kind of file.

Know a better way?

If you can do better, submit your command here.

What others think

cat overload!

< $localfile ssh $remote_host "cat > $remotefile"

(and what's with the capitalization? :-)
