(newbie) search & replace (—match case) all at once without confirmation automation

(newbie) search & replace (—match case) all at once without confirmation automation

[jindam, vani]

hello emacs users,

after trying several gui text editors, i 
hesistantly installed & familiarising emacs.
so far, good. i have decided to use as default 
text editor.

my search contains characters such as { or - or = 
and alphabets. in other cli/gui editors, i choose 
"match case" and "replace all".
for example: "{{cite", "agree=yes"

straight to point:
* where can i find examples for "search & replace 
(—match case) all at once without confirmation"?
* is it possible to use more than one for 
search & replace? i mean, i want to replace 
"{{cite", "agree=yes" at once?
* if i cant use more than one, how do i automate?

regards,
jindam, vani

By default, search is case insensitive (unless your search
string has mixed case).

To change that, you change the value of the variable `case-fold-search'
(try: M-x customize-variable, then `case-fold-search': you get a buffer
with a button where you can switch it on or off).

There are multiple other ways to achieve that, of course.

Once you get your search-and-replace running, it will stop at the first
match. There you can type 'y' or just SPACE to effect the replacement,
'n' to skip to the next match. If you want to do "all the rest", you
just type '!'. There is a little message at the bottom of your edit
window which tells you that (and the other options you have).

That said, I'd recommend that you walk the extra mile and learn
"incremental search". For one you get immediate feedback while
you are entering your search string; then, you can pick up parts
of your buffer text to complete your search string. You can change
case sensitivity on the fly, change between regular expression and
literal string on the fly, too, and lastly, upgrade your search
to a search-and-replace.

Sounds complicated, but you don't have to learn everything at once.
It's woth it :)

Cheers

i always assumed emacs as pure cli, but i was wrong.
my immediate priority is to find one click solution.
i have noted your tips, thank you. i will try today 
and if i have any issues, i will ask here.

It can be a GUI but to most people it is a TUI ...

It can, but it won't force you. Actually, I do use the menus
from time to time -- on things I don't do very frequently.

When I find myself repeating something, I look up the command
key sequence.

I hope they were helpful & enjoyable :)
