du

Synopsis

du [-sant] [file...]


-s (default)	Output the usage information tallied for each directory.
-a	Output usage information for each file, not just the directories.
-n	Output just the filenames, no other information. Warning messages are generated for 'unsafe' filenames (i.e., names containing shell special characters or characters that might confuse certain tools). The unsafe characters are: `" ' \Q $ # ; & \| ^ < > ( ) \`
-t	When used with the `-n` option, outputs the filename, modification time (seconds since the epoch), size (in bytes), and checksum. This option has no effect in the absence of the `-n` option.

sh	Description of special characters
stat	obtaining file sizes
