    1. 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

    2. If by all permissions you mean 777

      Navigate to folder and

      chmod -R 777 .

    3. 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.

    4. Yes, very right that the -R option in chmod command makes the files/sub-directories under the given directory will get 777 permission. But generally, it’s not a good practice to give 777 to all files and dirs as it can lead to data insecurity. Try to be very specific on giving all rights to all files and directories. And to answer your question:

      chmod -R 777 your_directory_name

      … will work

    5. This didn’t work for me.

      sudo chmod -R 777 /path/to/your/file/or/directory

      I used -f also.

      sudo chmod -R -f 777 /path/to/your/file/or/directory

    6. To help you with your doubt, if at all you are going for a console command it would be by using:

      chmod -R 777 /www/store.

      The -R (or –recursive) options make it repetitive. If desired by you, you could make all the files in the current directory have all permissions type by using:

      chmod -R 777 ./

    7. Best Answer

      If you’re a Linux user or a system administrator managing a Linux server, you’ll come across the “You do not have the permissions to upload file to the folder” error. After some Googling, the solution is often as easy as setting the file permission to “775” or “777.” In technical terms, you will be asked to “chmod 777 the file.” But what does “777” mean? And why must it be “7” and not “8” or “9”?

      Permissions. These determine what the user can do with a file. You can either Read, Write, or Execute a file, and you’re able to set almost any combination of these three permissions.

      • Read. You cannot modify the contents of the file in any way. When applied to a Folder, you can only view the files within that folder; you cannot delete or modify the files in any way or add more files to the folder.
      • Write. You can modify the file. If you have “write” access to a folder, then you can delete and add files to that folder.
      • Execute. Execute is mainly used when you need to run the file and is most commonly used when you need to run a script.

      Explaining File Permission 777

      Once you have a basic understanding of Classes and Permissions, you can begin to understand numbers such as “777” and “775.”

      Every file and folder contains 8-bit data that controls the permissions. In its basic binary form, 000 means that no permissions of any form are granted.

      When you set a “Read” permission, it adds 4-bit to the data, making it “100” (in binary format) or a “4” in the usual decimal format. Setting a “Write” permission will add 2-bit to the data, making it “010” and “2” in decimal form. Lastly, setting an “Execute” permission adds 1-bit to the data, which will result in “001,” or “1” in decimal form. In short:

      • Read is equivalent to “4.”
      • Write is equivalent to “2.”
      • Execute is equivalent to “1.”

      In a nutshell, setting permissions is basic math. For example, to set “Read and Write” permissions, we combine 4 and 2 to get 6. Of course, there are other permutations:

      • 0: No permission
      • 1: Execute
      • 2: Write
      • 3: Write and Execute
      • 4: Read
      • 5: Read and Execute
      • 6: Read and Write
      • 7: Read, Write, and Execute

      A complete set of file permissions assigns the first digit to the Owner, the second digit to the Group, and the third to Others. Here are some of the commonly used permissions:

      • 755. This set of permissions is commonly used by web servers. The owner has all the permissions to read, write and execute. Everyone else can read and execute but cannot make changes to the file.
      • 644. Only the owner can read and write. Everyone else can only read. No one can execute this file.
      • 655. Only the owner can read and write and cannot execute the file. Everyone else can read and execute and cannot modify the file.

      As for 777, this means every user can Read, Write, and Execute. Because it grants full permissions, it should be used with care. However, in some cases, you’ll need to set the 777 permissions before you can upload any file to the server.
