Procedure
Download the relevant CLI.
Unpack the archive:
$ tar xvzf <file>-
Place the
tknbinary in a directory that is on yourPATH. To check your
PATH, run:$ echo $PATH
6.1.2. Installing Red Hat OpenShift Pipelines CLI (tkn) on Linux using an RPM

6.2. Configuring the OpenShift Pipelines tkn CLI
Configure the Red Hat OpenShift Pipelines tkn CLI to enable tab completion.
6.2.1. Enabling tab completion
After you install the tkn CLI, you can enable tab completion to automatically complete tkn commands or suggest options when you press Tab.
