[Gnuplot-info] how to execute OS command using gnuplot defined variables

[Jon <dev...@gm...>]

Hello,

I am trying to do something like this

s=1
f1='../aaa/bbb_' . s . 'i.hist'
!vi f1
p f1 u 1:2 w l

The purpose to doing that is to see what's in the file f1 before drawing it
(for debugging purpose). However, it seems vi takes f1 as the file name,
instead of taking aaa/bbb_1i.hist as the file.

Any idea how to deal with this?

Thanks,
Jon
