Chmod 777 to a folder and all contents

If you are going for a console command it would be:

chmod -R 777 /www/store. The -R (or --recursive) options make it recursive.

Or if you want to make all the files in the current directory have all permissions type:

chmod -R 777 ./

If you need more info about chmod command see: File permission

If by all permissions you mean 777

Navigate to folder and

chmod -R 777 .

You can give permission to folder and all its contents using option -R i.e Recursive permissions.

But I would suggest not to give 777 permission to all folder and it's all contents. You should give specific permission to each sub-folder in www directory folders.

Ideally, give 755 permission for security reasons to the web folder.

sudo chmod -R 755 /www/store

Each number has meaning in permission. Do not give full permission.

N   Description                      ls   binary    
0   No permissions at all            ---  000
1   Only execute                     --x  001
2   Only write                       -w-  010
3   Write and execute                -wx  011
4   Only read                        r--  100
5   Read and execute                 r-x  101
6   Read and write                   rw-  110
7   Read, write, and execute         rwx  111

• First Number 7 - Read, write, and execute for the user.
• Second Number 5 - Read and execute for the group.
• Third Number 5 - Read and execute for others.

If your production web folder has multiple users, then you can set permissions and user groups accordingly.
