rapt-file

RAPT-FILE(1)															      RAPT-FILE(1)

NAME

       rapt-file - APT package searching utility -- search remotely

SYNOPSIS

       rapt-file [ options ] [ action ] [ pattern ]

DESCRIPTION

       rapt-file  is  a command line tool for searching files in packages for the APT package management system.  It differs from apt-file in that
       it works with remote package indices, so it doesn't need to download full Contents files.

       find   Alias for search.

       list   List the contents of a package matching the pattern pattern. This action is very close to the dpkg -L  command  except  the  package
	      does not need to be installed or fetched.

       search Search in which package a file is included. A list of all packages containing the pattern pattern is returned.

	      rapt-file will only search for filenames, not directory names.  This is due to the format of the Contents files it searches.

       show   Alias for list.

OPTIONS

	  -a, --architecture architecture
	      Sets architecture to architecture. This option is useful if you search a package for a different architecture from the one installed
	      on your system.  It determines how the $ARCH variable in sources.list is expanded (but it does not influence the search in any other
	      way).

	  -l, --package-only
	      Only display package name; do not display file names.

	  -v, --verbose
	      Run rapt-file in verbose mode.

	  -h, --help
	      Display a short help screen.

FILES

       /etc/apt/sources.list
	      Locations to fetch package contents from.

       /etc/apt/sources.list.d/
	      Directory with additional sources.list snippets
