FILE

Overwrite a file to hide its contents, and optionally delete it

shred

Change permissions to allow writing if necessary

Overwrite N times instead of the default (3)

Shred this many bytes (suffixes like K, M, G accepted)

'unlink' => use a standard unlink call, 'wipe' => also first obfuscate bytes in the name, 'wipesync' => also sync each obfuscated byte to the device

Like -u but give control on HOW to delete

Do not round file sizes up to the next full block; this is the default for non-regular files

Add a final overwrite with zeros to hide shredding
