NAMEapt-cyg - package manager utilitySYNOPSISapt-cyg [operation] [options] [targets]DESCRIPTIONapt-cyg is a package management utility that tracks installed packages on aCygwin system. Invoking apt-cyg involves specifying an operation with anypotential options and targets to operate on. A target is usually a packagename, file name, URL, or a search string. Targets can be provided as commandline arguments.OPERATIONSinstallInstall package(s).removeRemove package(s) from the system.updateDownload a fresh copy of the master package list (setup.ini) from theserver defined in setup.rc.downloadRetrieve package(s) from the server, but do not install/upgrade anything.showDisplay information on given package(s).dependsProduce a dependency tree for a package.rdependsProduce a tree of packages that depend on the named package.listSearch each locally-installed package for names that match regexp. If nopackage names are provided in the command line, all installed packages willbe queried.listallThis will search each package in the master package list (setup.ini) fornames that match regexp.categoryDisplay all packages that are members of a named category.listfilesList all files owned by a given package. Multiple packages can be specifiedon the command line.searchSearch for downloaded packages that own the specified file(s). The path canbe relative or absolute, and one or more files can be specified.searchallSearch cygwin.com to retrieve file information about packages. The providedtarget is considered to be a filename and searchall will return thepackage(s) which contain this file.mirrorSet the mirror; a full URL to a location where the database, packages, andsignatures for this repository can be found. If no URL is provided, displaycurrent mirror.cacheSet the package cache directory. If a file is not found in cache directory,it will be downloaded. Unix and Windows forms are accepted, as well asabsolute or regular paths. If no directory is provided, display currentcache.OPTIONS--nodepsSpecify this option to skip all dependency checks.--versionDisplay version and exit.
