Linux newbie question about deleting files

I'm wondering why every time I deleted files (using the rm command) on my Linux server, the used disk space for the files seemed not to be freed up? I mean the free disk space status stayed the same after I deleted the files.

Am I missing something or is there any command I should run to force the system to recalculate the free disk space?

Thanks in advance!
