Echo hangs and loops infinitely

[tpizza]

If I echo out to a file, the command runs, but it loops infinitely and recursively writes to the target file.

Here's my use-case as to why I'm even performing an echo:

I really enjoy the safeguard in password protecting my SSH key. Not so much for the extra 'security', but it gives me a brief moment to decide if there's something I forgot and back out of a push. I'm in the process of automating an upstream setup using Gulp where I need to use a password-less key to handle the subtree setup. The point of the echo is to write to the SSH config to change the key to the p/w-less one for setting, pulling and merging the subtree, then restoring it once the process completes.

This is all you need to reproduce:

GULP.task('_homez', () => { return GULP.src('./**/**') .pipe( PLUGINS.exec('echo test > test.txt') ) .pipe( PLUGINS.exec.reporter()); } );

./**/** grabs everything including node_modules. It ran fine for me,
but took a long time. Switch to echo test >> test.txt to see how many
times it ran. Add a !./node_modules/**/** glob or otherwise limit the
input file list so it'll do less work.

Interesting. When I switched the command to append the echoes, I got to about 8 tests until I killed the task. For a second I thought maybe it was because the task was trying to also run through the IntelliJ project folder, but it would still hang even with !./.idea/**/**. I got it working, however instead of the wildcard glob, I passed src the project root ./ and the task would successfully finish.

Glad you got it solved. I wonder if the shell was waiting to read a locked file.
