How to clear a file via adb?

Question

Similarly to how I view file, using adb functionality:

adb shell cat /path/to/file

I would like to clear a file, without having to enter adb shell, like so:

adb shell clear /path/to/file

Second example is a pseudo-code ofc.

Answer 1

This should clear the file, removing every text in the file:

adb shell "> /path/to/file"
