Vi, replace text -

-

i have text this

template template template_results template

and need replace this

template_form template_form template_results template_form

how can replace every match of template not followed _ character in vi?

i tried this

:%s/template[^_]/template_form    - pattern not found :%s/template\[^_]/template_form   - pattern not found :%s/template[_]/template_form     - works, pattern opposite of need

thank :)

use negative lookahead:

:%s/template\(_\)\@!/template_form/gc

this means match "template" not followed (\@!) "_"

see: :help /zero-width
