Get run command from stdout

Hi, I’m often running multiple commands in dvc run, which can be done by wrapping the command in quotes:

dvc run -d in.txt -o out.txt 'cp in.txt out.txt; for i in {1..10}; do echo ${i} >> out.txt; done'
# Running command:
# 	cp in.txt out.txt; for i in {1..10}; do echo ${i} >> out.txt; done

It would be nice if I could input the command using stdout prompt instead, e.g. by running:

dvc run -d in.txt -o out.txt --interactive
# > Enter command:
cp in.txt out.txt; for i in {1..10}; do echo ${i} >> out.txt; done
# Running command:
# 	cp in.txt out.txt; for i in {1..10}; do echo ${i} >> out.txt; done

In your example you are lucky because you didn’t specify -d option last before your command. If you would to do that, there would be no way for a parser to distinguish between where the deps end and where the commands starts.

Indeed, @efiop , introducing a --cmd flag or handling -- correctly to stop the parser could work, however, I wasn’t taking into account Windows users (maybe globbing wouldn’t work the same way), so it would be nice to have some agnostic / non-shell dependent way to handle this 👍

Looks like we could close this. Please feel free to reopen, if I’ve missed something.
