To chmod to change the permissions for all subdirectories. Luckily, there’s a command-line option for changing permissions in subdirectories ( recursively). However, files in the Mail subdirectory remain unchanged. Usually, you automatically have read/write permission for files you own- but not always (for example, if the file was transferred from somewhere else). The letter u represents the owner (user), and +rw adds read and write permission. This command gives the owner read/write permissions for the file called who.out. The owner of a file can also add or subtract permissions for himor herself.
