directory restore 755 :
find /path/of/files -type d -exec chmod 755 {} \;files restore 644 :
find /path/of/files -type f -exec chmod 644 {} \;if you made a misteake with chown , that’s more simple :
chown username. -R /path/of/files \;username : is the username you want to assign permissions.

chown username:group -R /path/of/files \;
