Issues redirecting stdout
0
I seem to be having issues with the simplest of things. I can't redirect stdout to a file. 100% my output is coming via '1' stdout. Including the redirect of stderr makes no difference (as you would expect since it's output destined for stdout). All of the below commands produce a file with 0 contents. No errors are thrown. Running on a rasp pi with newest raspbian.
uname -mrv:
4.14.98-v7+ #1200 SMP Tue Feb 12 20:27:48 GMT 2019 armv7l
command | tee test.file # ideal functionality
command > test.file # This doesn't work

If you are actually usingcommandand that isn't just a placeholder for the actual command that you are using then neither of those give any output which is why your file is 0 bytes. You will actually need the command to send something to standard output before it can be redirected to a file.command -vwill do this.
