Forums Scripts & Popups /ShowDesktop

I made a simple ShowDesktop alias that writes to (Show Desktop.scf) then runs the file.



It works fine but my question is, would it be a better idea to check to see if it's a file and then run it or just simply delete the file that gets written to after every time I type the command? Also, would the above work for OS's earlier than XP I can only test on this XP machine and I want it to be able to work for everyone.

I have excluded the part to check whether or not

Thanks in advance.

I would make a simple if $exists(%x) check to see if the code exist in the dir before writting a new file everytime.

Check if it exists and run it. Use $isfile() though, not $exists()

Ah right, will do that. Cheers mate.

Two things should be noted regarding $isfile() vs $exists():

$isfile() is useful if you want to make sure that when you /run %x, you won't get an Explorer window opening the folder %x that might happen to exist in the current folder.

However, if you assume that you can safely /write %x if $isfile() returns $false, you can run into problems, because if the folder %x exists in the current folder, you cannot create a file named %x there. In such cases, you'd need to use $isdir() or $exists().

What I'd do in this case is first check $exists(). If it returns $false, /write the file and /run it right away. Otherwise, also check $isfile(); if it returns $true, /run it right away, otherwise /write using another filename and /run it.

Of course, things can still go wrong if the file %x exists but contains other stuff than those .ini sections, but checking that is a bit too much; one might as well create a unique file anyway.
