Удалите файл, например:
sudo shred -u /dev/disk/by-id/<your_filename>
И как говорит Терренс в комментариях:
Лучше взять время, чтобы устранить, тогда чтобы сожалеть в будущем.из man shred
shred - overwrite a file to hide its contents, and optionally delete it
-n, --iterations=N
overwrite N times instead of the default (3)
-u, --remove[=HOW]
truncate and remove file after overwriting; See below
Delete FILE(s) if --remove (-u) is specified. The default is
not to remove the files because it is common to operate on device
files like /dev/hda, and those files usually should not be removed.
The optional HOW parameter indicates how to remove a directory entry:
'unlink' => use a standard unlink call. 'wipe' => also first
obfuscate bytes in the name. 'wipesync' => also sync each obfuscated
byte to disk. The default mode is 'wipesync', but note it can be
expensive.
