[SOLVED] Help with sed command !

Hi,

I want to use sed to modify a source file. I use sed so that I can integrate it into a PKGBUILD.

I use this command :

sed -e 's/NEW_RESIZE_CODE 1/NEW_RESIZE_CODE 0/' guiconfig.h

It does exactly what I want. But now I want to directly modify the file and overwrite its content so I do :

sed -e 's/NEW_RESIZE_CODE 1/NEW_RESIZE_CODE 0/' guiconfig.h > guiconfig.h

But when I open the file, it is empty ! Note that it works if I use a different filename than the original input filename !!!

Any idea ?

Heh I did the same thing recently whilst attempting to correct a typo in some schoolwork and wiped the file - luckily git came to the rescue.
Moral: backup files when playing with things you don't fully understand. Actually, backup files in general.
