.SH "NAME"
port-platform \- Print the OS version for which MacPorts was built

.SH "DESCRIPTION"
.sp
This command prints the version of your operating system used to configure and build MacPorts\&. This value is used to detect OS updates and refer users to the \m[blue]\fBMigration\fR\m[]\&\s-2\u[1]\d\s+2 instructions\&.
.sp
Since MacPorts picks up a number of paths at configure\-time and uses them later on, changes in the operating system can break a MacPorts installation\&. For example, this happened when Apple removed \(lq/usr/bin/gnutar\(rq with the release of OS X Mavericks\&. Since MacPorts keeps the path to its tar command in a file, this change required rebuilding MacPorts\&.
.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\&.
