+** Changing permission for directories
+
+Let's say I (unintentionally) changed the permissions for a directory that
+contains multiple subdirectories. Let's call that directory "buds"
+
+I can't access the files without being `root`. This is the outuput in the
+command line When a list the directory using `ls -la`.
+
+ 
+#+begin_example bash
+  drw-r--r--  81 user user     4096 dec 26 06:21  buds              
+#+end_example
+
+When I go to my git repository and check the change I can see this output for
+every file within the directory:
+
+#+begin_example bash
+  diff --git a/doc/index.rst b/doc/index.rst
+  old mode 100644
+  new mode 100755
+#+end_example
+
+
+This is how the permission could be changed:
+
+Note that, in this case, it's necessary to use `sudo` before the command to
+access the files
+
+#+begin_src bash
+  chmod -R o=wxr,g=xr,o=x buds
+#+end_src
+
+
+*** The output now is:
+
+#+begin_example bash
+  drw-r-x--x  81 user user    4096 dec 26 06:21  buds
+#+end_example
+
+Remember how it looks before
+
+#+begin_example bash
+  drw-r--r--  81 user user    4096 dec 26 06:21  buds_before
+#+end_example
+
+But I still can open the files. That is because need to change the owner from 755
+to 644:
+
+#+begin_example bash
+  chown -R 755 /etc/myfiles
+#+end_example
+
+ps: should use`sudo` to run this command
