""" NAME shred - delete a file securely, first overwriting it to hide its contents SYNOPSIS shred [OPTIONS] FILE [...] DESCRIPTION Overwrite the specified FILE(s) repeatedly, in order to make it harder for even very expensive hardware probing to recover the data. Mandatory arguments to long options are mandatory for short options too. -f, --force change permissions to allow writing if necessary -n, --iterations=N Overwrite N times instead of the default (25) -s, --size=N shred this many bytes (suffixes like K, M, G accepted) -u, --remove truncate and remove file after overwriting -v, --verbose show progress -x, --exact do not round file sizes up to the next full block -z, --zero add a final overwrite with zeros to hide shredding - shred standard output --help display this help and exit --version output version information and exit """ There are real reasons why this might not *actually* work. Be aware of caches, buffers, journals, snapshots, flushes, and RAIDs, oh my!
