Re: Check if a package is installed

Hello.

I would like to know how to reliably test if a Cygwin package is already
installed (just like setup.exe does).

Currently, I test the existence of /etc/setup/<package>.lst.gz. It works
perfectly for me, but a user reported to me that that file was missing
sometimes.

I see there is also package information listed in
/etc/setup/installed.db. Maybe this information should be considered as
more reliable?


cygcheck -c <package>


It uses the the two information left by setup.exe
 /etc/setup/installed.db
 /etc/setup/<package>.lst.gz

to provide a status.
