Question

I want to replace old by new string by using call:Rep(new,old) . So my pseudo code is like this…

I am new to vimscript , I don’t know how to do it.

function! Rep(old,new)
   !sed -i.bak 's/#{old}/#{new}/g' *
endfunction

Do you have any idea?
Thanks.

Answer 1

Change your function to

function! Rep(old,new)
   exe "!sed -i.bak 's/".a:old."/".a:new."/g' *"
endfunction

then use :call Rep(old,new). You can also create a command for it.

command! -nargs=+ Rep call Rep(<args>)

so that you can do :Rep old new.
