PKG_CHECK(1) BSD Reference Manual PKG_CHECK(1)
pkg_check - shell interface to pkgtools matching routines
pkg_check version1 op version2 pkg_check [-q] -m pattern pkgname ...
The pkg_check command provides functions to check package versions in MirPorts. It is meant to be called from scripts, not directly from the command line. There are two distinct modes of operation. The first one, which takes three arguments, compares the two version strings version1 and version2. The second argument, the operator, is one of <, >, <=, >= or the text equivalents lt, gt, le and ge. The exit code is 0 if the comparison is true or 1 if it is false. The second mode allows to check whether one or more package names pkgname match the pattern given as the argument to the -m flag. Unless -q (quiet) is given, the matching package names are written to standard output, one per line. The exit status is 0 if there was at least one match, 1 other- wise.
pkg_check 1.4.5 ge 2.0 returns 1. pkg_check 23.42-0 '<' 23.42-5 returns 0. pkg_check -m 'autoconf->=2.50' autoconf-2.13 autoconf-2.62 prints "autoconf-2.62".
