Normally, count=n means read(2) will be called n times on the input to dd. If
the read() returns short, as may happen when reading from a pipe, fewer bytes
will be copied from the input. With conv=sync the buffer is padded with zeros
to fill the rest of the block.
iflag=fullblock causes dd to continue reading until the block is full, so that

The pipefail option allows checking the exit status of all commands in a

similarly to the option in bash, ksh93 and mksh.
Like ksh93 and unlike bash and mksh, the state of the option is saved when a

a later change of the option does not change the exit status, the same way

-P was introduced in 4.4BSD-Lite2 around 1994. It overwrote file contents
with a pass of 0xff, 0x00, then 0xff, in a low effort attempt to "really
delete" files.
It has no user-visible effect; at the end of the day, the file is unlinked via
the filesystem. Furthermore, the utility of overwriting files with patterned
data is extremely limited due to caveats at every layer of the stack[0] and
therefore mostly futile. At the least, three passes is likely wasteful on
modern hardware[1]. It could also be seen as a violation of the "Unix
Philosophy" to do one thing per tiny, composable program.
Since 1994, FreeBSD has left it alone; OpenBSD replaced it with a single
pass of arc4random(3) output in 2012[2]; and NetBSD implemented partial, but
explicitly incomplete support for U.S. DoD 5220.22-M, "National Industrial
Security Program Operating Manual" in 2004[3].
NetBSD's enhanced comment above rm_overwrite makes a strong case for removing
the flag entirely:
> This is an expensive way to keep people from recovering files from your
> non-snapshotted FFS filesystems using fsdb(8). Really. No more.
>
> It is impossible to actually conform to the exact procedure given in
> [NISPOM] if one is overwriting a file, not an entire disk, because the

> Any program that claims to securely erase *files* while conforming to the

As a first step towards evental removal, make it a placebo. It's not like
it was serving any security function. It is not defined in or mentioned by
POSIX.
If you are security conscious and need to erase your files, use a
woodchipper. At a minimum, the entire disk needs to be overwritten, not
just one file.

The difference between EXERROR and EXEXEC was that EXEXEC passed along

You should not be using DES. You should not have been using DES for the
past 30 years.
The ed DES-CBC scheme lacked several desirable properties of a sealed
document system, even ignoring DES itself. In particular, it did not
provide the "integrity" cryptographic property (detection of tampering), and
it treated ASCII passwords as 64-bit keys (instead of using a KDF like
scrypt or PBKDF2).
Some general approaches ed(1) users might consider to replace the removed
DES mode:
1. Full disk encryption with something like AES-XTS. This is easy to
conceptualize, design, and implement, and it provides confidentiality for
data at rest. Like CBC, it lacks tampering protection. Examples include
GELI, LUKS, FileVault2.
2. Encrypted overlay ("stackable") filesystems (EncFS, PEFS?, CryptoFS,
others).
3. Native encryption at the filesystem layer. Ext4/F2FS, ZFS, APFS, and
NTFS all have some flavor of this.
4. Storing your files unencrypted. It's not like DES was doing you much
good.
If you have DES-CBC scrambled files produced by ed(1) prior to this change,
you may decrypt them with:
openssl des-cbc -d -iv 0 -K <key in hex> -in <inputfile> -out <plaintext>
