How to Change Permissions For a Folder and Its Subfolders/Files

How do I change permissions for a folder and its subfolders/files?

The other answers are correct, in that chmod -R 755 will set these permissions to all files and subfolders in the tree. But why on earth would you want to? It might make sense for the directories, but why set the execute bit on all the files?

I suspect what you really want to do is set the directories to 755 and either leave the files alone or set them to 644. For this, you can use the find command. For example:

To change all the directories to 755 (drwxr-xr-x):

find /opt/lampp/htdocs -type d -exec chmod 755 {} \;

To change all the files to 644 (-rw-r--r--):

find /opt/lampp/htdocs -type f -exec chmod 644 {} \;

Some splainin': (thanks @tobbez)

  • chmod 755 {} specifies the command that will be executed by find for each directory
  • chmod 644 {} specifies the command that will be executed by find for each file
  • {} is replaced by the path
  • ; the semicolon tells find that this is the end of the command it's supposed to execute
  • \; the semicolon is escaped, otherwise it would be interpreted by the shell instead of find

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

Set permissions for directorys/subdirectorys/files

You have to add another AccessRule with InheritanceFlags set to ContainerInherit AND ObjectInherit.

To get the permissions to propgate to child folders, the PropagationFlag is set to Inherit only.

Here's an example below

    public void PropogateSecurity(string userid,string directory)

var myDirectoryInfo = new DirectoryInfo(directory);
var myDirectorySecurity = myDirectoryInfo.GetAccessControl();
myDirectorySecurity.AddAccessRule(new FileSystemAccessRule(userid, FileSystemRights.Modify, InheritanceFlags.ContainerInherit, PropagationFlags.InheritOnly, AccessControlType.Allow));
myDirectorySecurity.AddAccessRule(new FileSystemAccessRule(userid, FileSystemRights.Modify, InheritanceFlags.ObjectInherit, PropagationFlags.InheritOnly, AccessControlType.Allow));


You can also do this with recursion, but the above would be my preferred method as cleaning up permissions would be annoying.

Permission denied from a subfolder

The issue was coming from PHP 5.6.26. Using PHP 5.6.40 fixed it.

I reset to my original permissions and everything is fine!
