/bin/sh provider

[stepancheg]

Something like this:

"providers": [{
  "type": "shell",
  "sh": "gsutil cp gs://foo/bar/baz.tgz @DOTSLASH_OUT@"
}]

This can be used as S3 provider #30 or GCP provider #32.

This feels dangerous (albeit useful). Not a huge fan of @DOTSLASH_OUT@. I like that tar's --use-compress-program assumes that stdout is the output. Is that too limiting for the use cases you see?

[stepancheg]

One can always either:

• pass /dev/stdout as argument
• do something like gsutil cp gs://foo/bar/baz.tgz $TMPDIR/xx && cat $TMPDIR/xx if a program cannot write to /dev.

I suspect the latter option will be used practically, so I proposed @DOTSLASH_OUT@. Should be easier to debug too (when command fails, dotslash would print the exact command that failed, that can be just pasted into a terminal).

But piping to stdout as the only option will not be a blocker.
