Unix permissions

I have a file of which I need to change contents, that has these permissions:

-rw-r--r--

How do I find out which permissions group I belong to, so I can do a chmod command?

I just tried to do chmod and I got an error:

$ chmod 777 hosts
chmod: Unable to change file mode on hosts: Operation not permitted

Here is my ls -l

-rw-r--r--  1 root  wheel  313 Apr 16 13:04 hosts

This is what solved my problem

Make sure you are the owner of the file go to the root file, right click then go to more info at the bottom you can set permissions, hit the plus sign to give your self read + write permissions after that hit the gear option and make yourself the owner

in the root file run 

sudo chmod 777 *

if doing this in react native to start up your app run 

sudo npm start

and you should be good to go

'ls -l' will tell you all you need to know.

Permissions Directories Group   Size    Date            Directory or file 
drwx------  2           users   4096    Nov 2 19:51     mail/

If you have root permission, try a 'sudo chmod 777 hosts'.

If you have a super user's password you could always :

$ sudo chmod 777 hosts

which, of course, is never a very good idea.

the owner of the file will need to change permissions or change ownership by using chown,

here are some examples: http://en.wikipedia.org/wiki/Chown

You are probably not the owner of the file.
