HI,
Well there is no way to recover a deleted file or folder in Sun Solaris and as well as other variant of Unix...Since as soon as the file or folder get deleted, the unix operating system releases the it as free space...and as soon as a file need more disk space...it uses the deleted disk space first!! So there is no way to receover it unless you don't add disk space to your computer...-> but logs files does...but as a rule of thumb...you should always set a aliases for rm to mv to a ./WASTE folder...or rm -i to confirm you want to delete....this can prevent you from accidently removing files....also during a .logout, you can add rm -rf ./WASTE, that way when you logout, your waste basket automatically get empty.
Hope that can help you a bit.
Thanks,
Hui
