Re: A list of installed packages (no dependencies) -- this may help
Is there in Cygwin a command to recover a list of installed packages chosen by
the user without the dependencies?
For example, the archlinux package manager with
pacman -Qqe pkglist
can save the list of package chosen by the user only and this is useful in
case
one wants/needs to reinstall all the packages.
Hi Angelo,
I replied to your entry in an earlier attempt, but my reply got stuck in the
machinery
at sourceware.org (my message had a shell script and a .bat file attached).
Below (I hope) you will find a script, that may be of help to you ...
It computes the top vertices of the forest (i.e. the dependency graph), i.e.
the pkgs
that no other pkg depends on (within the context of a specific installation of
Cygwin).
In my case, it reduced a list of 161 pkgs to one of only (about) 15 pkgs.
(using a .bat file - quiet-install.bat - which I will attempt to include as
well, I
installed Cygwin afresh and verified the result)
Of course your situation may be different from mine ... then somebody else may
find good
use of the script.
