Thanks for this quick fix! Left a couple comments, otherwise this is a great help.

Actually, I believe correct behavior (comparing against v0.7.8) is to never print this. So, this should be silent: true.

just to clarify, here silent: true will always be there?

In my previous comment, I intended for you to change this line to:

common.error(stderr, code, { continue: true, silent: true });

This test is great. Can you also add a second test to handle the case for silent: false?

Optional suggestion: you can replace the command with shell.exec('shx ls resources/file1.txt filethatdoesnotexist'). shx ls is cross-platform, guaranteed to produce both stdout & stderr, and guaranteed to have a non-zero exit code.

Above you suggested that silent will always be true, then there will be no silent: falsecase?

Above you suggested that silent will always be true

For this PR, correct behavior is to always pass { silent: true } to common.error(), regardless of config.silent or exec's { silent: true } option.

then there will be no silent: false case?

I think two cases are interesting:

when the user passes silent: true, there should be no stdio

when the user passes silent: false (or, equivalently, the default), the command's stdio should go to stdio, but exec should not also print exec: <something here> to stderr

Does this make sense?

@uttpal any update?

I will fix and add test asap

test/exec.js


 const CWD = process.cwd();
 const ORIG_EXEC_PATH = shell.config.execPath;
 shell.config.silent = true;

This line is OK as written. This actually exposes a bug (#862), which I will handle.

FYI fix is uploaded (#863). It's OK if this PR lands first.

Any update on this? The current work around is to globally silent the module using sh.config.silent = true so the build-in log function doesn't output anything. It would be nice if this PR could be merged and released.

nfischer · 2018-09-20T20:00:54Z

I believe I still need a change from @uttpal (if that's not the case, please let me know I should re-review this).

nfischer · 2018-10-10T02:46:52Z

FYI I cherry-picked this to #892

Unconditionally apply `silent: true` when calling `common.error()` from `exec()`. This is because errors are already printed to stderr, or are intentionally silenced by `shell.config.silent`. Based on #861 Fixes #851
