I use linux Fedora Core4. Normally, rm command will delete file(s) and then give me back a space. Yesterday, I deleted file "/home/www/web3/log/error.log" which was 17GB of its size. After deleting, the available size on my server (viewed by using "du -kh" ) was still the same as before deletion. Could anyone help me to solve this, and how can I do?
