This article demonstrates the process of chmod file and subfolder permissions per directory, using the command line.
If you have installed files which need mass permission modifications, all located in a similar directory on the server, you can use the command line to chmod and quickly fix the permissions. We will be using the find command in this process.
chmod Directory and Subdirectories
First, login to the server via ssh. As the root user, execute a similar command, where /home/username/public_html/blog is the directory you are modifying permissions for:
# find /home/username/public_html/blog -type d -exec chmod 755 {} \;
This will modify permissions of /blog and all subfolders to 755 (drwxr-xr-x).
chmod Files Within Directory
As the root user, execute a similar command, where /home/username/public_html/blog is the directory you are modifying permissions for:
# find /home/username/public_html/blog -type f -exec chmod 644 {} \;
This will modify permissions of all files below /blog directory to 644 (-rw-r--r--).
