A shared web hosting server running CentOS 7.8 with Plesk has the following directory structure for a few hundred vhosts:
/var/www/vhosts/domain1.com/httpdocs/
/var/www/vhosts/domain2.com/httpdocs/
/var/www/vhosts/domain3.com/httpdocs/
httpdocs folder contains the web files in Plesk, like the standard public_html directory on Apache/cPanel.
I'm after a command or script to go through each vhosts domain directory and recursively chmod everything inside httpdocs - files to 644 and folders to 755 via SSH. There are other directories directly inside /domain1.com/, /domain2.com/ etc. so they shouldn't be touched, only the contents inside of httpdocs.
