.SH "NAME"
port-installed \- List installed versions of a given port, or all installed ports
.SH "SYNOPSIS"

.SH "DESCRIPTION"
.sp
\fBport installed\fR can be used in two separate ways: Either without arguments, in which case it will print a list of all installed ports (both active and inactive), or with arguments, which will return a list of installed ports that match the argument expression\&.
.sp
The output of \fBport installed\fR contains the name, version and variants of the installed ports and whether the port is active or inactive\&. See the PORT IMAGES section for an explanation of the active/inactive state\&.
.SH "GLOBAL OPTIONS"
.sp
Please see the section \fBGLOBAL OPTIONS\fR in the \fBport\fR(1) man page for a description of global port options\&.
.PP
\fB\-v\fR
.RS 4
Print the platform at install time (i\&.e\&., your OS X version) and the architecture(s) of the installed port\&.
.RE
.PP
\fB\-q\fR
.RS 4
Do not print the header line\&. This is useful when parsing the output of
\fBport installed\fR
in scripts for further processing\&.
.RE
.SH "PORT IMAGES"
.sp
MacPorts has the ability to install multiple versions or different variant selections of the same port\&. The files will be stored in an intermediate location as \fIarchives\fR, which allows to switch between the versions\&. Only one version can be active at a time\&. On activation, files will be copied to their intended place in \fIprefix\fR\&.
.sp
More information on this topic can be found in the \m[blue]\fBThe MacPorts Guide\fR\m[]\&\s-2\u[1]\d\s+2\&.
.sp
To check the current status of a specific port, use \fB\fBport-installed\fR(1)\fR\&.
