The most basic ls option for viewing file and folder ownership and permissions is –l:
MacBook:~ tejashweta$ ls -l
drwxr-xr-x+ 11 201 _guest 352 May 15 2016 Guest
drwxrwxrwt 6 root wheel 192 Oct 24 02:34 Shared
drwxr-xr-x+ 39 tejashweta staff 1248 Apr 4 12:03 tejashweta
Please goto particular folder or file to change permission.
chmod 775 <file name> / <folder Name>
