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.
