I legitimately use this line in one of my scripts because range.find returns an error of the value is not found. The use case is taking a 2d matrix saved as an array, with data collected from multiple excel tabs and rearranging it for a CSV upload into Salesforce. The initial array contains values that the rest of the data does not have, so when I search for a non existent value, I can skip the error.
Of course vba COULD just implement try/catch statements and that'd be so much cleaner, but alas.
No, > /dev/null 2>&1 is. If try your example but with file instead null, stderr content not in file.
Because x>y not redirect x to y, but duplicate y and set x to y-duplicate. See bash manpage REDIRECTION (your example in that section for what not work).
As i understand, your example set 2 to what 1 is, then set 1 to null. Now 2 not null, but what 1 before.
Trying to hide problems and incompetence is the joke. A lot of people don't want problems solved, they just don't want to see them, and will take the easy route. If you just want that, this is the easy route.
