The output of this command will be computer code and is meant to be saved to a
|
|
file or immediately evaluated by an interactive shell.
|
|
|
|
For example, for bash you could add this to your '~/.bash_profile':
|
|
|
|
eval "$(gh completion -s bash)"
|
|
|
|
When installing GitHub CLI through a package manager, however, it's possible that
|
|
no additional shell configuration is necessary to gain completion support. For
|
|
Homebrew, see https://docs.brew.sh/Shell-Completion
