"Ghost" output from locate?

Question

I deleted some files, but they seem to still exist. Can anyone please explain the output of this:

m@work:~$ locate cfx.css | xargs rm 
m@work:~$ locate cfx.css
/var/www/wfox/hbr.co.nz/cfx/a/c/cfx.css
/var/www/wfox/modules/gallery/cfx/a/c/cfx.css
/var/www/wfox/phoenix/fp.co.nz/cfx/a/c/cfx.css
/var/www/wfox/tmp.co.nz/cfx/a/c/cfx.css
m@work:~$ cat /var/www/wfox/hbr.co.nz/cfx/a/c/cfx.css
cat: /var/www/wfox/hbr.co.nz/cfx/a/c/cfx.css: No such file or directory

Answer 1

Run sudo updatedb then re-run your locate, expect you'll find it's just that locate's database is not current since you've only just deleted the files concerned.
