I have a program on a remote host, whose execution I need to automate. The command execute that program, on the same machine, looks something like this:

```
/path/to/program -a file1.txt -b file2.txt

```

In this case, `file1.txt` and `file2.txt` are used for entirely different things within the program, so I can't just `cat` them together. However, in my case, the `file1.txt` and `file2.txt` that I want to pass into the program exist only on my device, not on the host where I need to execute the program. I know that I can feed at least one file through SSH by passing it through `stdin`:

```
cat file1.txt | ssh host.name /path/to/program -a /dev/stdin -b file2.txt

```

but, since I'm not allowed to store files on the host, I need a way to get the `file2.txt` over there as well. I'm thinking it might be possible through abuse of environment variables and creative use of `cat` and `sed` together, but I don't know the tools well enough to understand how I would use them to accomplish this. Is it doable, and how?
