<!-- Please use this template while reporting a bug and provide as much info as possible. Not doing so may result in your bug not being addressed in a timely manner. Thanks! If the matter is security related, please disclose it privately via --What happened: Running silently fails if that source file doesn't exist. What you expected to happen: I expected kubectl to exit with a non-zero status code and to print a standard error message like so: How to reproduce it (as minimally and precisely as possible): Find any running pod, try to copy a non-existent file: Anything else we need to know?: works right. For example: I'm sure this has something to do with the fact that uses under the hood. However, itself will report an error if you try to extract a file that doesn't exist, so maybe this is just a matter of not including the to-be-extracted-path(s) on the end of the tar command line. This might be fixed by appending (or rather the basename of it) to the end of the array here: (haven't tried it).

This is the first example where I found the kubectl cli to be sub-par (otherwise the experience has been excellent). Is anyone looking at this?

For me never copies anything and never writes any info to console. Even if I point it to non-existing pod, it just exists with no trace.
I've opened with a fix.
: what version of kubectl are you using? I tried to upload a file to a non-existent pod and it failed with an error message (using the master branch) :

Any maintainer here? I had opened with a fix.
Would be great if would return a simple error in the CLI. Our pipeline was failing for a month and none realised because all the kubectl results were green :heavycheckmark:
