.SH "NAME"
equery \- Gentoo: Package Query Tool
.SH "SYNOPSIS"
.B equery  
.I [global\-opts] command [local\-opts]
.PP 

.SH "DESCRIPTION"
equery is a flexible utility which may display various information about 
packages, such as the files they own, their USE flags, the md5sum 
of each file owned by a given package, and many other things.

.SH "OPTIONS"
The 'command' is the only mandatory option to equery.  Most commands require
a 'pkgspec' option, which is described by <cat/>packagename<\-version>;
namely, the package name is mandatory, while the category and version are 
optional.

[global\-opts] may be one of:

.B \-q, \-\-quiet   
causes minimal output to be emitted
.PP 
.B \-C, \-\-nocolor 
turns off colours
.PP 
.B \-h, \-\-help
displays a help summary
.PP 
.B \-V, \-\-version
displays the equery version
.PP 
.B \-N, \-\-no\-pipe
turns off pipe detection
.PP 

Only one command will actually be run, at most.  The possible commands are: 
.TP 
.B belongs <local\-opts> file
This command lists all packages owning the specified file.
.br 
Note: Normally, only one package will own a file. If multiple packages own the
same file, it usually consitutes a problem, and should be reported (http://bugs.gentoo.org).
.br 
.IP 
<local\-opts> is either or both of:
.br 
.B \-c, \-\-category cat 
only search in category cat
.br 
.B \-f, \-\-full\-regex
supplied query is a regex
.br 
.B \-e, \-\-earlyout 
stop when first match found

.PP 
.B check pkgspec
This command checks the files of the specified package against recorded MD5 
sums and timestamps.
.PP 
.TP 
.B depends <local\-opts> pkgspec
This command displays all dependencies matching pkgspec.
.br 
<local\-opts> is either or both of:
.br 
.B \-a, \-\-all\-packages
search in all available packages (slow)
.br 
.B \-d, \-\-direct
search direct dependencies only (default)
.br 
.B \-D, \-\-indirect
search indirect dependencies (very slow)
.br 
.B \-\-depth=n
Limit depth of indirect dependency tree to n levels. Setting \-\-depth=0 is the same as not specifing \-\-indirect.
.PP 
.TP 
.B depgraph <local\-opts> pkgspec
This command display a dependency tree for pkgspec, by default indented to reflect
how dependancies relate to each other.
.br 
.IP 
<local\-opts> is either or both of:
.br 
.B \-U, \-\-no\-useflags 
do not show USE flags.
.br 
.B \-l, \-\-linear    
do not use fancy formatting 
.br 
.B \-\-depth=n
Limit depth of dependency graph to n levels.
.PP 
.TP 
.B files <local\-opts> pkgspec
This lists files owned by a particular package, optionally with extra
information specified by <local\-opts>
.br 

<local\-opts> is any combination of:
.br 
.B \-\-timestamp
output the timestamp of each file
.br 
.B \-\-md5sum
output the md5sum of each file
.br 
.B \-\-type
output the type of each file
.br 
.B \-\-tree
display results in a tree (turns off all other options)
.br 
.B \-\-filter=<rules>
filter output based on files type or path
.br 
.B \t<rules>
is a comma separated list of filtering rules. Available rules are:
.br 
.B \t\tdir\ 
regular directories
.br 
.B \t\tobj\ 
regular files
.br 
.B \t\tsym\ 
symbolic links
.br 
.B \t\tdev\ 
device nodes
.br 
.B \t\tfifo

.br 
.B \t\tpath

.br 
.B \t\tconf
configuration files (based on $CONFIG_PROTECT)
.br 
.B \t\tcmd\ 
user commands (based on $PATH)
.br 
.B \t\tdoc\ 
documentation files (from /usr/share/doc)
.br 
.B \t\tman\ 
manpages (from /usr/share/man)
.br 
.B \t\tinfo
info pages (from /usr/share/info)
.PP 
.TP 
.B hasuse <local\-opts> useflag
This command lists packages matching a particular USE flag in a user\-specified combination
of installed packages, packages which are not installed, the portage tree, and
the portage overlay tree.

<local\-opts> must not include only \-I;
if \-I is used, \-p and/or \-o must be also be present.  By default, only installed
packages are searched.  \-o searches only the overlay tree [and possibly
installed packages],
.I not
the main portage tree.

.B \-i, \-\-installed
search installed packages (default)
.br 
.B \-I, \-\-exclude\-installed
do not search installed packages
.br 
.B \-p, \-\-portage\-tree
also search in portage tree (/usr/portage)
.br 
.B \-o, \-\-overlay\-tree
also search in overlay tree (/usr/local/portage)
.PP 
.TP 
.B list <local\-opts> pkgspec
This command lists packages matching pkgspec in a user\-specified combination
of installed packages, packages which are not installed, the portage tree, and
the portage overlay tree. By default the list command searches for partial name matches.

<local\-opts> \-I cannot be used by itself;
if \-I is used, \-p and/or \-o must be also be present.  By default, only installed
packages are searched.  \-o searches only the overlay tree [and possibly
installed packages],
\fInot\fR the main portage tree.

.B \-i, \-\-installed
search installed packages (default)
.br 
.B \-I, \-\-exclude\-installed
do not search installed packages
.br 
.B \-p, \-\-portage\-tree
also search in portage tree (/usr/portage)
.br 
.B \-o, \-\-overlay\-tree
also search in overlay tree (/usr/local/portage)
.br 
.B \-f, \-\-full\-regex
query is a regular expression
.br 
.B \-e, \-\-exact\-name
list only those packages that exactly match
.br 
.B \-d, \-\-duplicates
only list installed duplicate packages
.br 

\fBOutput:\fR

.br
The list command searches packages for the name given. If found, the following info will be displayed: the package location between the first square brackets (I for Installed packages, P for Portage, O for Overlay), the possible masks between the second (~ by keyword, - by arch or M hard masked), then the category and complete name and last of all, the slot in which the package is stored.

\fBExamples:\fR

equery list zilla \- list all installed versions of packages containing the string 'zilla'

equery list \-\-exact\-name x11\-libs/gtk+  \- list all installed versions of x11\-libs/gtk+

equery list \-\-full\-regex '(mozilla\-firefox|mozilla\-thunderbird)' \- list all installed versions of mozilla\-firefox and mozilla\-thunderbird 

equery list \-\-duplicates \- list all installed slotted packages
.PP 
.TP 
.B size <local\-opts> pkgspec
This command outputs the number of files in the specified package, as well as
their total size in an appropriate unit.

The possible values for <local\-opts>, if specified, are:
.br 
.B \-b, \-\-bytes 
report size in bytes
.br 
.B \-f, \-\-full\-regex
query is a regular expression
.br 
.B \-e, \-\-exact\-name
list only those packages that exactly match
.PP

.B uses <local\-opts> pkgspec 
display USE flags for pkgspec.

The only possible value for <local\-opts>, if specified, is:
.br 
.B \-a, \-\-all
include all package versions

.B which pkgspec 
print full path to ebuild for package pkgspec
