Differences between CHMOD 755 vs 750 permissions set

Question

I have some files with 755 and I need to change them to 750, but I am not sure if this can affect some process.

I am changing JARs, XMLs, LOGs, and properties files.<

Answer 1

0755 = User:rwx Group:r-x World:r-x

0750 = User:rwx Group:r-x World:--- (i.e. World: no access)

r = read
w = write
x = execute (traverse for directories)
