the test -s for the “if” statement

Question

I have a question and i would be grateful for the answer if somebody knows one. Ok, to the point. In one of my scripts i have following expression, it is not clear for me form m

Answer 1

This if command simply prints the string file is zero sized and not exist | is exist and zero sized | not exist (obviously zero sized) if the file does not exist or if the file is zero sized.

If you want your if command to check only for the zero sized file and not file existence then you can do something like this :

if [[ $(du -h "$the_file_to_check" |cut -f 1) == "0" ]] ;then echo "file is zero sized" ; fi

But this if statement will post a error if file does not exist. Make sure you execute this only when the file is present.
