[TxMt] preview in localhost

[salvo]

Hi,

sometimes I test anything (like html page and perl scripts) writing  
directly on Desktop, first to pass them in the correct localhost web  
site folders, so I've set Apache to handle also $USER/desktop as  
localhost directory.
I try to put in bundle editor, html this line:

open `echo $TM_FILEPATH | sed "s|.*/$USER/Sites/\(.*\)|http:// 
localhost/~$USER/desktop/\1|"`

but it doesn't work

Please, there is a solution?

Many thanks in advance

Salvo
