Thanks, this is what I looked for.


However, I notice that:

1) If the .lst.gz file is missing, "cygcheck -c <package>" still reports
OK.

a package with a missing .lst.gz , should be a obsolete and empty. Usually are package labels left to pull in the alternative package.


2) When testing a missing package, "cygcheck -c <package>" does not output any status line, but its return code is still 0. This is not easy to use from scripts.


try using grep.


I damaged the xv package as following:

$ cygcheck -c  -v xz
Cygwin Package Information
Last downloaded files to: e:\downloads\cygwin_cache
Last downloaded files from: http://mirrors.dotsrc.org/cygwin/

Package              Version              Status
Missing file: /usr/bin/xz.exe from package xz
xz                   5.0.2_20110517-1     Incomplete


using grep I can find the failing package


$ cygcheck -c xz |grep OK ; echo $?
1

while usually I have

$ cygcheck -c xz |grep OK ; echo $?
xz                   5.0.2_20110517-1     OK
0
