+
+Using `umask` one can set the file permissions that are set when creating a new file. 
+
+Maximum permissions allowed for files and directories are differerent: 
+- Files max: 0666
+- Dirs max: 0777
+
+Thus take care when setting `umask` because the effect is different on files than directories.
+
+To get the correct mask, just subtract the mask from the maximum permissions. For example, mask 0066 would create files 0600 < 6 - 6 = 0.
+This same umask would make directories with 0711.
