osx - how to change extended file attributes of files on mac? -

-

i had ios projects in macbook,one day copied them pc based on windows system, day copied them macbook , found projects can not run. opened 1 of projects xcode, says "builde successfully",but app can not deployed on iphone simulator if simulator running!?!?!?! check files using "ls -l" command , found difference between normal xcode project files , new created xcode project files symbol.

files problem:

    drwx------+ 49 dingvimer  staff   1.6k

normal file：

    drwx------@ 60 dingvimer  staff   2.0k

how can change '+' symbol '@' , project run normally?

i appreciate kindness of helping me figure out (^-^).

you can use ls -l@ see extended attributes. show like:

drwxr-xr-x@ 5 cody  staff  170 mar 30 08:46 test.xcodeproj lastupgradecheck      4

lastupgradecheck - name of attribute (sometimes there can com.apple.blablabla) , 4 - value.
use xattr command set/delete extended attributes. see man xattr (its quite short , there examples).
note, you'll need fix whole project directory.
