for many days this file (Alias) wont disappear, and i dont know how it ended up in the Trash anyway.. i have attached a pic for it.. hope i can find the answer here,, thank you guys
hmm - okay, it sounds like you've got some file corruption in there.
Richthomas has the right approach, so I won't say it again - just make sure that you're in your home directory before you enter those commands (which should be fine as that's terminal's default directory when it starts up unless you've changed something).
tersono & richthomas thanks for ur help, i tried everything i know, including disk Utilities - repair disk but still never worked,, nvm i'll go to the place wer i bought my macbook from.. thnx again
