vercmp <version1> <version2>
vercmp is used to determine the relationship between two given version numbers. It outputs values as follows:
< 0 : if ver1 < ver2
= 0 : if ver1 == ver2
> 0 : if ver1 > ver2
Version comparison operates as follows:
Alphanumeric: 1.0a < 1.0b < 1.0beta < 1.0p < 1.0pre < 1.0rc < 1.0 < 1.0.a < 1.0.1 Numeric: 1 < 1.0 < 1.1 < 1.1.1 < 1.2 < 2.0 < 3.0.0
Additionally, version strings can have an epoch value defined that will
overrule any version comparison, unless the epoch values are equal. This is
specified in an
epoch:version-rel format. For example,
2:1.0-1 is always
Keep in mind that the pkgrel is only compared if it is available on both
versions given to this tool. For example, comparing
yield 0; comparing
1.5-2 will yield < 0 as expected. This is
mainly for supporting versioned dependencies that do not include the pkgrel.
