all files in current directory, including sub directories of URL path?

• httrack –mirror URL

• Which files are new? After a new install of some web application, I wanted to see which files were new and perhaps which files had I added to my installation. You can use the -1 option to ls to get all the files output 1 per line and run a diff.

 $ ls -1 dir_old/ > d1
 $ ls -1 dir_new/ > d2
 $ diff d1 d2
