List system information, check installed packages, or query package database.

At least one command option or a PROGRAM is required, as shown above.

  PROGRAM              list library (DLL) dependencies of PROGRAM

  -c, --check-setup    show installed version of PACKAGE and verify integrity

                       (or for all installed packages if none specified)

  -d, --dump-only      just list packages, do not verify (with -c)

  -s, --sysinfo        produce diagnostic system information (implies -c)

  -r, --registry       also scan registry for Cygwin settings (with -s)

  -k, --keycheck       perform a keyboard check session (must be run from a

                       plain console only, not from a pty/rxvt/xterm)

  -f, --find-package   find the package to which FILE belongs

  -l, --list-package   list contents of PACKAGE (or all packages if none given)

  -p, --package-query  search for REGEXP in the entire cygwin.com package

                       repository (requires internet connectivity)

  --delete-orphaned-installation-keys

                       Delete installation keys of old, now unused

                       installations from the registry.  Requires the right

                       to change the registry.

  --enable-unique-object-names Cygwin-DLL

  --disable-unique-object-names Cygwin-DLL

  --show-unique-object-names Cygwin-DLL

                       Enable, disable, or show the setting of the

                       "unique object names" setting in the Cygwin DLL

                       given as argument to this option.  The DLL path must

                       be given as valid Windows(!) path.

                       See the users guide for more information.

                       If you don't know what this means, don't change it.

  -v, --verbose        produce more verbose output

  -h, --help           annotate output with explanatory comments when given

                       with another command, otherwise print this help

  -V, --version        print the version of cygcheck and exit

Note: -c, -f, and -l only report on packages that are currently installed. To

  search all official Cygwin packages use -p instead.  The -p REGEXP matches

  package names, descriptions, and names of files/paths within all packages.
