Posted to VIM Syntax Highlighting over 1 year ago

actually you can do something like

echo "syntax on" >> ~/.vimrc

My guess this tip is very similar to https://coderwall.com/p/n1abyq

Actually you can also use use -O and -p params. Let's check man vim:

-o[N]       Open N windows stacked.  When N is omitted, open one window for each file.
-O[N]       Open N windows side by side.  When N is omitted, open one window for each file.
-p[N]       Open N tab pages.  When N is omitted, open one tab page for each file.
