Command completion for boinc_client and boinc_cmd
The bash shell has a useful facility to complete commands when you press [TAB]. There is a script which goes a bit further and lets bash complete boinc_client's? and boinc_cmd's? commands and options.
For example if you type boinc_cmd --get_[TAB] it gives you all commands which begin with --get_:
--get_cc_status --get_project_status --get_disk_usage --get_proxy_settings --get_file_transfers --get_results --get_host_info --get_screensaver_mode --get_messages --get_simple_gui_info --get_project_config --get_state --get_project_config_poll
If you now press 'p' the selection is reduced to:
--get_project_config --get_project_status --get_project_config_poll --get_proxy_settings
and so on. The script also completes host names after the --host option.
To use this command completion, save the following script on a file and source it in bash.
