Short: `Output bash completion script for rclone.`,
Long: `
Generates a bash shell autocompletion script for rclone.
By default, when run without any arguments,
2017-08-31 14:52:51 +00:00
rclone genautocomplete bash
2017-08-31 14:52:51 +00:00
the generated script will be written to
2017-08-31 14:52:51 +00:00
/etc/bash_completion.d/rclone
2017-08-31 14:52:51 +00:00
and so rclone will probably need to be run as root, or with sudo.
If you supply a path to a file as the command line argument, then
the generated script will be written to that file, in which case
you should not need root privileges.
If output_file is "-", then the output will be written to stdout.
If you have installed the script into the default location, you
can logout and login again to use the autocompletion script.
Alternatively, you can source the script directly
. /path/to/my_bash_completion_scripts/rclone
and the autocompletion functionality will be added to your
current shell.
