Is there a way to make sed ask me for confirmation before each replace? Something similar to 'c' when using replace inside vim.

Does sed do this at all?

It would be technically possible but more of an intellectual exercise than a useful endeavor. See How to do a text replacement in a big folder hierarchy? which has Vim and Perl solutions. – Gilles Sep 6 '11 at 0:20
    
I am using vim (args and argdo) whenever I need 'confirmation', but was wondering if there was a 'simpler' way – Yuvi Sep 7 '11 at 19:26
    
It goes against the basic purpose of sed - to automate editing over a stream. – teppic Oct 1 '15 at 17:24

Doing it with sed would probably be possible but would require far too much thinking. It is easier to just do it with vim:

vim -c '%s/PATTERN/REPLACEMENT/gc' -c 'wq' file.in

You can get this by doing such:

:%s/OLD_TEXT/NEW_TEXT/gc

Specifically, adding the c after the third delimiter.

Note that the 'c' option only works in Vim; you won't be able to use it with sed at the command line.

To clarify: this only works in Vim, not regular command line sed. – Brendan Oct 1 '15 at 15:28
