NAME

6       vercmp - version comparison utility
7

SYNOPSIS

9       vercmp <version1> <version2>
10

DESCRIPTION

12       vercmp is used to determine the relationship between two given version
13       numbers. It outputs values as follows:
14
15       ·   < 0 : if ver1 < ver2
16
17       ·   = 0 : if ver1 == ver2
18
19       ·   > 0 : if ver1 > ver2
20
21       Version comparison operates as follows:
22
23           Alphanumeric:
24             1.0a < 1.0b < 1.0beta < 1.0p < 1.0pre < 1.0rc < 1.0 < 1.0.a < 1.0.1
25           Numeric:
26             1 < 1.0 < 1.1 < 1.1.1 < 1.2 < 2.0 < 3.0.0
27
28       Additionally, version strings can have an epoch value defined that will
29       overrule any version comparison, unless the epoch values are equal.
30       This is specified in an epoch:version-rel format. For example, 2:1.0-1
31       is always greater than 1:3.6-1.
32
33       Keep in mind that the pkgrel is only compared if it is available on
34       both versions given to this tool. For example, comparing 1.5-1 and 1.5
35       will yield 0; comparing 1.5-1 and 1.5-2 will yield < 0 as expected.
36       This is mainly for supporting versioned dependencies that do not
37       include the pkgrel.
