unix - Permission code clarification needed -


I was reading some documents where a developer is saying that a fixed file + rx mode Because the file is being accessed by external services

What does this CHMOD code do? 777?

Thanks

+ rx means:

Generally, Urdu 022 and default permissions are 644, so the result will be 755.

calculated 0644 | (0555 & amp; ~ 0022) :

  + rx: 555 -> 101 101 101 Umascus: 022 - & gt; 000 010 010 & amp; ~ ====================== Add these permits: 555 - & gt; 101 101 101 Default Permissions: 644 - & gt; 110 100 100 ===================== RESULTS: 755 - & gt; 111 101 101
