git config --global pager.branch false

Disables the use of a pager for the output of the `git branch` command globally.

This command is used to modify the configuration of the git system on a global level.

By specifying --global, it updates the global git configuration file located in the user home directory.

The pager.branch setting is when you want to control if git should send output of branch command to a 'pager' (like less or more). The false value disables the usage of a pager for the output of the branch command across all repositories on the system.

Variations of this command could involve setting other pager settings to true or false. For instance, git config --global pager.status true, enables the usage of a pager for the output of the status command.
