.SH "DESCRIPTION"
|
|
.sp
|
|
\fBport select\fR provides a mechanism to choose from different implementations of a common tool or port\&. Selecting one of the options makes it the primary version or implementation, e\&.g\&. the one to be run by default when you do not explicitly select a version or implementation on the command line\&.
|
|
.sp
|
|
Note that \fBport select\fR is only for your convenience as user\&. It does not, for example, affect which compiler MacPorts uses when it compiles software, or against which copy of MySQL a port builds\&. If there is a user\-visible choice, it is usually offered as a variant on the port\&. If the \fBport select\fR mechanism affects how a port builds, that should be considered a bug\&.
|
|
.sp
|
|
One example is the set of MySQL and forks of MySQL, where there are mysql51, mysql55, mysql56, mariadb, mariadb\-10\&.0, mariadb\-11\&.0, percona, possibly among others\&. \fBport select\fR lets you choose which of these becomes the version run, when you simply run \fImysql\fR or other commands from the MySQL suite\&.
|
|
.sp
|
|
\fBport select\fR has multiple modes of operation: It can display a summary, show the current primary implementation and list all available implementations given a group name, and change the primary implementation\&. See \fBOPTIONS\fR below for details\&.

\fBport select\fR

is called with one argument\&.

Make

\fIoption\fR

the primary selection for the
|
|
\fIgroup\fR
|

group\&. This is the default when
|
|
\fBport select\fR
|

is called with two arguments\&.

If you have both the mysql56 and the percona port installed, you can switch your implementation of the \fImysql\fR command by running
|
|
.sp
|
|
.if n \{\
|
|
.RS 4
|
|
.\}
|
|
.nf
|
|
$> sudo port select \-\-set mysql $option
|
|
.fi
|
|
.if n \{\
|
|
.RE
|
|
.\}
|
|
.sp
|
|
where \fI$option\fR is \fImysql56\fR if you want the version from MySQL, or \fIpercona\fR, if you want the version from Percona\&.
