app-portage/version

Version command is a package that is used for the following tasks:

1. get version information of a package.
2. operate with version of a package.

Make the program available by adding guru repository:

root #eselect repository enable guru

root #emaint sync -r guru

Install the package:

root #emerge --ask app-portage/version

Display available options:

user $version -h

For example, use the following command to the version of 'gentoolkit' package:

user $version -g app-portage/gentoolkit

0.5.0

Use 's' option to check if the version is smaller than the specified version (in this case 1.0):

user $version -c app-portage/gentoolkit s= 1.0

true

or (if the shell accepts a more friendly syntax):

user $version -c app-portage/gentoolkit <= 1.0

true

Descriptive outputs can be enabled with 'i' option:

user $version -ci app-portage/gentoolkit s= 1.0

app-portage/gentoolkit : pass(0.5.0)

There is also an option to get the current platform:

user $version -p
