I've created a wxpython gui for the shred command. I can successfully mix and match all the shred options except two: -size and --random-source. (Man page definitions below). -size and --random-source seem to only work when they are used as the sole option passed.
shred with not perform what I'm intending it to do.
Anyone know the syntax necessary to use -size and -random-source options along with the others?
From the man page:
Code:
-f, --force
change permissions to allow writing if necessary
-n, --iterations=N
Overwrite N times instead of the default (25)
--random-source=FILE
get random bytes from FILE (default /dev/urandom)
-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;
this is the default for non-regular files
-z, --zero
add a final overwrite with zeros to hide shredding
