how to open same file in same tab for commandline vim

I kno开发者_高级运维w another session said use :drop can do it but I only use command line vim. Is there a plugin can do it? Thanks

I think what you want is set switchbuf=usetab in your .vimrc.

With this set you can then do :sb <part-of-filename-or-buffer-number> to switch to the tab or window that has that buffer open. In this example: :sb A.

See :help 'switchbuf' for more information.

Is vim -o the_file the_file what you want?

I am not sure I understand you question correctly but:

e -> reloads the active file.
e myfile.txt-> opens another file in the active tab.
