Provide a way to redirect stdout/stderr into a file #5511
Description
Description of the problem / feature request:
It is common for programs in unix world to output the result of an invocation to stdout. The current way to capture that output is to either use ctx.actions.run_shell() or a wrapping shell script to redirect it to a file. This requires spawning an extra process and hence adds some overhead. Perhaps it makes sense to provide a way for ctx.actions.run() to redirect stdout and/or stderr into a file.
Feature requests: what underlying problem are you trying to solve with this feature?
I have a tool that does what I described above - writes the result of its invocation to stdout. I need to capture that output and put it into a file - it is the output of the rule. Currently I have to wrap it in a shell script and I thought it might be good to suggest this feature. Thanks.
