strange behaviour

[ghost]

i just start using Vim in Ubuntu terminal.

while i press "-" and from list select the file it always end up opening in new split. how can i make it to open in same split.

That should be the default. Check your config; netrw provides an option I do believe.

the settings name is
let g:netrw_browse_split=0

from help netrw_browse_split:

g:netrw_browse_split when browsing, will open the file by:
=0: re-using the same window (default)
=1: horizontally splitting the window first
=2: vertically splitting the window first
=3: open file in new tab
=4: act like "P" (ie. open previous window)
Note that |g:netrw_preview| may be used
to get vertical splitting instead of
horizontal splitting.
