portageq is a tool to quickly query Portage information. It is primarily used by Gentoo developers in order to determine Portage configuration information.
Every Gentoo system should have portageq installed. Run a quick test by issuing the the
--help option as seen in the usage section below.
If usage instructions are not displayed to the terminal there is certainly a problem. It is possible to (re)install Portage by following the Portage installation instructions.
>>> Portage information query tool >>> 188.8.131.52 >>> Usage: portageq <command> [<option> ...] Available commands: all_best_visible <eroot> Returns all best_visible packages (without .ebuild). available_eclasses <eroot> <repo_id>+ Returns space-separated list of available eclasses for specified repository. best_version <eroot> <category/package> Returns highest installed matching category/package-version (without .ebuild). best_visible <eroot> [pkgtype] <atom> Returns category/package-version (without .ebuild). The pkgtype argument defaults to "ebuild" if unspecified, otherwise it must be one of ebuild, binary, or installed. colormap Display the color.map as environment variables. config_protect Returns the CONFIG_PROTECT paths. config_protect_mask Returns the CONFIG_PROTECT_MASK paths. contents <eroot> <category/package> List the files that are installed for a given package, with one file listed on each line. All file names will begin with <eroot>. distdir Returns the DISTDIR path. eclass_path <eroot> <repo_id> <eclass>+ Returns the path to specified eclass for specified repository. envvar <variable>+ Returns a specific environment variable as exists prior to ebuild.sh. Similar to: emerge --verbose --info | egrep '^<variable>=' expand_virtual <eroot> <atom> Returns a \n separated list of atoms expanded from a given virtual atom (GLEP 37 virtuals only), excluding blocker atoms. Satisfied virtual atoms are not included in the output, since they are expanded to real atoms which are displayed. Unsatisfied virtual atoms are displayed without any expansion. The "match" command can be used to resolve the returned atoms to specific installed packages. filter_protected <eroot> Read filenames from stdin and write them to stdout if they are protected. All filenames are delimited by \n and must begin with <eroot>. gentoo_mirrors Returns the mirrors set to use in the portage configuration. get_repo_path <eroot> <repo_id>+ Returns the path to the repo named argv, argv = $EROOT get_repos <eroot> Returns all repos with names (repo_name file) argv = $EROOT has_version <eroot> <category/package> Return code 0 if it's available, 1 otherwise. is_protected <eroot> <filename> Given a single filename, return code 0 if it's protected, 1 otherwise. The filename must begin with <eroot>. license_path <eroot> <repo_id> <license>+ Returns the path to specified license for specified repository. list_preserved_libs <eroot> Print a list of libraries preserved during a package update in the form package: path. Returns 1 if no preserved libraries could be found, 0 otherwise. mass_best_version <eroot> [<category/package>]+ Returns category/package-version (without .ebuild). mass_best_visible <eroot> [<type>] [<category/package>]+ Returns category/package-version (without .ebuild). The pkgtype argument defaults to "ebuild" if unspecified, otherwise it must be one of ebuild, binary, or installed. master_repos <eroot> <repo_id>+ This is an alias for the master_repositories command. master_repositories <eroot> <repo_id>+ Returns space-separated list of master repositories for specified repository. match <eroot> <atom> Returns a \n separated list of category/package-version. When given an empty string, all installed packages will be listed. metadata <eroot> <pkgtype> <category/package> [<key>]+ Returns metadata values for the specified package. Available keys: DEFINED_PHASES,DEPEND,DESCRIPTION,EAPI,HDEPEND,HOMEPAGE,INHERITED,IUSE,KEYWORDS,LICENSE,PDEPEND,PROPERTIES,PROVIDE,RDEPEND,REQUIRED_USE,RESTRICT,SLOT,SRC_URI owners <eroot> [<filename>]+ Given a list of files, print the packages that own the files and which files belong to each package. Files owned by a package are listed on the lines below it, indented by a single tab character (\t). All file paths must either start with <eroot> or be a basename alone. Returns 1 if no owners could be found, and 0 otherwise. pkgdir Returns the PKGDIR path. portdir Returns the PORTDIR path. Deprecated in favor of get_repo_path command. portdir_overlay Returns the PORTDIR_OVERLAY path. Deprecated in favor of get_repos & get_repo_path or repos_config commands. pquery [options] [atom]+ Emulates a subset of Pkgcore's pquery tool. repos_config <eroot> This is an alias for the repositories_configuration command. repositories_configuration <eroot> Returns the configuration of repositories. vdb_path Returns the path used for the var(installed) package database for the set environment/configuration options. Pkgcore pquery compatible options: usage: portageq pquery [options] [atom ...] Repository matching options: --no-filters no visibility filters (ACCEPT_KEYWORDS, package masking, etc) --repo REPO repository to use (all repositories are used by default) Package matching options: --herd HERD exact match on a herd --maintainer-email MAINTAINER_EMAIL comma-separated list of maintainer email regexes to search for Output formatting: -n, --no-version collapse multiple matching versions together
Querying environment variables
Probably the only question users will have as they read through the help output above is the definition of eroot. eroot simply means the repository filesystem path (directory) and can be obtained by:
portageq envvar EROOT
Return the CONFIG_PROTECT variable value (should be a filesystem path):
Return the DISTDIR variable value (should be a filesystem path):
Return the PKGDIR variable value (should be a filesystem path):
Query repository information
To see a detailed list of repositories as configured in repos.conf, without any formatting:
portageq repos_config /
As before, but without details:
portageq get_repos /
Simply put, removing the package management system on Gentoo is a bad idea. Do not do it!
