Thanks for the comment. I've forgotten to test the script on 32-bit Windows.
Now it uses a bash-specific variable to determine the CPU type and should work OK.

Also after some time of using I've completely rewritten it having added new
functionality and renamed it to 'cygcheck-dep'.

Neat.  I toyed a bit with your script and I like it.  This could
come in handy to isolate installation problems.  I uploaded the
package.  Please send an announcement along the lines of the
existing announcements to the cygwin-announce list.


Thanks,
Corinna

This needs to be in cygwin-pkg-maint and we'll need information as per:
https://sourceware.org/cygwin-apps/package-upload.html .

Also, FWIW, this package didn't really go through the vetting process of
getting the required number of votes.  I don't object to it going in but
I don't think we want to get into the habit of short circuiting
published procedures without at least acknowledging that we are doing
so for a reason.

Did so while uploading.

Well, it's just a small helper script and it looked useful enough, but
you're right, of course.

Ah, I was looking for cygcheck-leaves.  Nevermind.

[ITP] cygcheck-leaves - a script to list installed packages not required by any

[Mikhail Usenko]

As soon as setup.exe hasn't got an option to uninstall a package along with its requirements which have become unused after uninstalling that package, and cygcheck utility also does not provide any information on package dependencies I have written a bash script to list installed Cygwin packages which are not required by any other installed packages (that is package leaves in the dependency tree).

Developers usually have many lib*-devel packages installed on their system, these packages and others are required only as build dependencies so I think this script will be useful primarily for ordinary users who experiment with software and want to keep their Cygwin installation clean. They will be able to check the list of installed packages for unneeded ones.

I would like to propose this script as a Cygwin package if you appreciate it. The name of the script can be changed according to Cygwin policy on the use of cyg- prefix for such a type of programs.

setup.hint:

category: Utils
requires: bash coreutils sed wget bzip2
sdesc: "List installed Cygwin packages which are not required by any other installed packages"

I like the idea, but your script doesn't work as expected:

$ ./cygcheck-leaves -v
--2013-10-18 09:54:19--  ftp://sourceware.org/pub/cygwin/x86_64-cygwin/setup.bz2
           => `/var/cache/cygcheck-leaves/x86_64-cygwin/.listing'
Resolving sourceware.org... 209.132.180.131
Connecting to sourceware.org|209.132.180.131|:21... connected.
Logging in as anonymous ... Logged in!
==> SYST ... done.    ==> PWD ... done.
==> TYPE I ... done.  ==> CWD (1) /pub/cygwin/x86_64-cygwin ...
No such directory `pub/cygwin/x86_64-cygwin'.

That should be x86_64, not x86_64-cygwin.  The reason is that HOSTTYPE
has been already set by tcsh, and tcsh has another idea of that
variable than bash.

There's also the problem that, even under bash, the HOSTTYPE for 32 bit
is i686, but the directory on sourceware is called x86.

I guess what you want is something along the lines of

  targetdir=$(uname -m)
  [ "${targetdir}" = "i686" ] && machine='x86'
  setup_bz2_url="ftp://sourceware.org/pub/cygwin/${targetdir}/setup.bz2"


Thanks,
Corinna
