missing 'which' documentation

missing 'which' documentation

[Lee D. Rothstein]

Does anybody know or care that there is an option --
'-a' -- for 'which' -- that is not documented on
Cygwin. That is, there is no internal help, and there
is no 'man' or 'info' page provided by Cygwin install.
If anybody wants this, I will find or create the 'man'
page and make it cover '-a', and then do *what* with
it? Pointers appreciated!

To see the value of this option try (assuming you have MS
executable directories in your path):

  which ping              vs         which -a ping
  which find              vs         which -a find

and

  which dir               ==         which -a dir

i.e., 'dir' is an internal of 'cmd.exe'

my "info which" says

`--all'
`-a'
     Print all matching executables in `PATH', not
just the first.

but I am using the 2.16 version of cygwinports :-)

Cygwin's which is quite an old one written by me.  The best way to move
forward would probably be to remove it from the Cygwin distro in favor
of the which used in several (all?) Linux distros:

Anybody volunteering to become which maintainer for Cygwin?

Ha.  I just saw this subject and though "man which", then I got hungry.

Heh heh... Care to write a little more about that? I didn't see a base
package (other than the cygport packager tool) or installation with
that version number, but was delighted to see a port of glib there.
That will be very useful for those apps that expect glib and won't
build under newlib.

I recall (perhaps even correctly :) ) that SunOS had a "where" command
with the functionality of your 'which -a'. The idea was that "where"
would show you all scripts and executables of a given name in your
command path (ie. "where" they are), while "which" would tell you
*which* one of them would execute at the shell prompt. So unusual, to
see a pair of utilities whose names were so nearly self-explanatory. :)
Is the Linux "which" like yours (ie. 'which -a' == SunOS 'where')?

Yes.

Uhm... thanks! :) Guess I forgot to mention it, but that is where I saw
glib, but didn't see a base package (other than the cygport tool)-- I
do make some effort to research things first before posting questions,
and this site turned up near the top of a Google search. I also saw
their pages on http://sourceforge.net/projects/cygwin-ports/ but
searching the two (very low volume) mailing lists for "2.16" turned up
nothing useful. Finally, I added ftp://sunsite.dk/projects/cygwinports
as a user URL to setup.exe as suggested on the cygwinports home page
(nice of them to maintain a setup.ini file so that their users don't
have to figure out package dependencies) and looked at the packages
listed for install, but didn't see anything in the "base" category that
is any different from what standard Cygwin mirrors show, even with
"Exp"(erimental versions) selected. So I am still curious to know about
this cygwinports package that stands at ver. 2.16, and seems to have
documentation not included in the standard Cygwin packages.

glib != glibc.  And I don't see why this is specific to Cygwin Ports,
because the main Cygwin distro has glib and glib2 as well.  But again
these are *not* in any way related to glibc.

Yeah, I realized my error (faulty memory) just an hour or two ago when
I ran setup again and read the short package descriptions: glib is part
of GNOME, and Cygwin Ports doesn't have a port of glibc. :(

>And I don't see why this is specific to Cygwin Ports, because the main

It's not specific to CP-- they host the standard Cygwin distro as well,
which is convenient when a CP package has dependencies.

>But again these are *not* in any way related to glibc.

Yep, this error brought to you by an arguably POSIX-noncompliant
environment running on 52-year-old wetware, which is consequently
subject to bit rot from time to time...

would be good, though I realised that for programs,
like squid (whose cygwin port does not even seem to
work, but there is a windows port).. One is expected
to go online for the documentation!  So I consider an
internet connection somewhat mandatory -
unfortunately.

I have typed "man which", at google. I did notice that
cygwin had no man or info page for which.

on a related note- i also check
/usr/share/doc , since programs can put documentation
there, and furthermore, that documentation is
different, not conforming to the strict man page
format.

I guess there is no excuse for a simple thing like a
man page to not be installed - available offline. Even
a large man page is small enough, and this is a small
man page.
