- I always forget the precise encoding of permissions, so I mkae a cheat sheet to remember what's what. It's
read,write,execute which have values 2^2, 2^1, 2^0.
+-----+---+--------------------------+| rwx | 7 | Read, write and execute || rw- | 6 | Read, write || r-x | 5 | Read, and execute || r-- | 4 | Read, || -wx | 3 | Write and execute || -w- | 2 | Write || --x | 1 | Execute || --- | 0 | no permissions |+------------------------------------+
