Use: "autocomplete",

Short: "Generate shell autocompletion script for Hugo",
|
|
Long: `Generates a shell autocompletion script for Hugo.
|
|
|
|
By default, the file is written directly to /etc/bash_completion.d
|
|
for convenience, and the command may need superuser rights, e.g.:
|
|
|
|
$ sudo hugo gen autocomplete
|
|
|
|
Add ` + "`--completionfile=/path/to/file`" + ` flag to set alternative
|
|
file-path and name.
|
|
|
|
Add ` + "`--type={bash, zsh, fish or powershell}`" + ` flag to set alternative
|
|
shell type.
|
|
|
|
Logout and in again to reload the completion scripts,
|
|
or just source them in directly:
|
|
|
|
$ . /etc/bash_completion or /path/to/file`,
|
