27656a0cbc Audit env(1)
1) Shorten synopsis and reflect this in the manual
2) Use argv0 in usage()
3) Decrement argc in argv-loop for consistency
4) Make it clearer which error-code results from which errno in enprintf
5) Use idiomatic for-loop also for environ. Don't increment these pointers
   in the loop itself!

Before somebody gets the wrong idea again like I did.

286df29e7d Make already audited tools argv-centric instead of argc-centric
This has already been suggested by Evan Gates <>
and he's totally right about it.
So, what's the problem?
I wrote a testing program asshole.c with

        execl("/path/to/sbase/echo", "echo", "test");
        return 0;

and checked the results with glibc and musl. Note that the
sentinel NULL is missing from the end of the argument list.
glibc calculates an argc of 5, musl 4 (instead of 2) and thus
mess up things anyway.
The powerful arg.h also focuses on argv instead of argc as well,
but ignoring argc completely is also the wrong way to go.
Instead, a more idiomatic approach is to check *argv only and
decrement argc on the go.
While at it, I rewrote yes(1) in an argv-centric way as well.

All audited tools have been "fixed" and each following audited
tool will receive the same treatment.

Thanks Michael Forney <> for this observation!

d806f75cb6 Audit cat(1)
1) Fix usage ... spacing
2) use *argv instead of argv[0] in the idiomatic for-loop
3) Stop the naïve usage of "/dev/fd/0" and use plain stdin
   instead (This also makes error-messages more consistent).
4) Add newline before return
5) Remove comma in manpage

Nothing special, just a small style-fix.

Just a little usage()-fix. Mark it as audited in README.

0c9b52ef9b Update *sum(1)-manpages and mark them as finished and audited
Now that -c behaves correctly, the tools are pretty much done.
Only the manpages were not clear enough what happens when you
specify the c-flag.
This is fixed now.

9b06720f62 Refactor cryptcheck() to allow multiple list-files and stdin
Previously, it was not possible to use

sha1sum test.c | sha1sum -c

because the program would not differenciate between an empty
argument and a non-specified argument.
Moreover, why not allow this?

sha1sum -c hashlist1 hashlist2

Digging deeper I found that using function pointers and a
modification in the crypt-backend might simplify the program
a lot by passing the argument-list to both cryptmain and
Allowing more than one list-file to be specified is also
consistent with what the other implementations support,
so we not only have simpler code, we also do not silently
break if there's a script around passing multiple files to

1) argc style
2) safeguard argv-loop as already seen in echo(1) with argc-decrement.

2) manpage cleanup
3) NOTE: The utility-functions will be evaluated separately.

Oh well, time to simplify the loop.
Also, change the comment on unreachable code to something more clear.

5be621dcf2 Refactor basename.1 2015-02-28 15:09:47 +01:00
e7c33c4af3 Audit basename(1)
1) be stricter which number of arguments is accepted (1 or 2)
2) basename already returns a pointer to "." is argv[0] is ""
3) No need to check for *p != '/', because basename() only returns
   a string beginning with '/' which has length 1, so if strlen(p)
   == 1, the only way for suffix to be "evaluated" is for off to
   be > 0, being equal to suffix being "", but "" != "/".
4) don't calculate strlen twice for each string. Store it in a
   ssize_t and check if it's > 0.

44bd931834 Add audit-section to README
Okay, so why another section?
The finished-section applies to general feature-completeness and
manual status. It somehow is not an indicator for general code-
clarity, so the audited-column reflects a thorough audit of the
underlying code and optimization.
Take a look at the upcoming basename(1)-patch for an example on
how this goes.
