I have two computers (
telos) running Debian 11. For some reason the
scp command fails with a weird error message.
This is the output:
jj@telos:~$ scp test.txt legend.local: __ __
If I try it the other way around, the amount of underscores and spaces varies:
jj@legend:~$ scp telos.local:test.txt . ______ __
Here is the output with the
jj@telos:~$ scp -v test.txt legend.local: Executing: program /usr/bin/ssh host legend.local, user (unspecified), command scp -v -t .

______ __ is the strangest error message I've ever gotten. What is wrong?
