vim equivalent in emacs %5,50s/serah_term/replace_term/gc

[iluvindo]

Hi I recently moved from vim to emacs and need help to search and replace
using line numbers(say between two lines 5 and 50).  This can be done in vim
as %5,50s/serah_term/replace_term/gc
What is equivalent in emacs?
Thanks,
Iluvindo

Activate 'active region highlighting' from Options menu, mark the  
region either by dragging with the mouse cursor or with the keyboard  
(M-g g 5 RET C-SPC M-g g 50 RET), and then substitute:

	M-x replace-string RET <from> RET <to> RET

The number of replacements in one line cannot be limited to one.  
Details can be found in the GNU Emacs tutorial (C-h t) or when asking  
for a description of the function:

	C-h f <function name> RET

There is also a hypertext based documentation:

	C-h i RET m emacs RET

There is also the function replace-regexp which uses regular  
expressions to search for a string and replace it with another one.

M-g?  So I did C-h k on M-g, and in a mini-or-whatever buffer at
screen bottom, a line saying "set-face: default m-g d, ......".

My question: how to grab that doc-line?

Trying to regionize it kills it, nor does it seem to be in *Messages*.

Thanks!,

M-g is a `command prefix'.  You can see the help of `M-g g' by typing
`C-h k M-g g'.  This opens a new buffer/window, and you can switch to
that window using `C-x o' (one more more times, if necessary), to copy
text, move around, etc.

If you are using a GUI version of Emacs, point with your favorite
pointing device and click somewhere in the help buffer.  It will become
the active buffer, and you can copy text, move around, and so on...

(Sorry for the very-late response!)

As you suggested, I (again) do:

C-h k   on  Meta(ie esc)-g(as in grep)

    and I still get that set-face thing in that one-line window-thingie
    down at the very bottom of the screen  

    , and that's before I even get a chance to enter that *second*
    g (In M-g g).

What do *you* get when you try it?


And I do your suggested C-x o (which of course I use
all the time) while sitting there at the end of
that set-face line (*in* that bottom-of-screen one-line window),
and the only effect is to erase that set-face line.

I'm using 21.3.2.

But I'm not in the help buffer!  I'm in that little ephemeral bottom-of-screen,
what, "mini window"?

In this version M-g goes right into the face!

M-g has become a command prefix in GNU Emacs 22. M-g g invokes the  
function goto-line. In earlier version(s) in invoked the set-face  
function.

Which ``doc-line´´? Do you mean what the key combination is doing/ 
stands for? C-h k <key combination>.

Could be there is also activation of transient-mark-mode necessary.  
And again: GNU Emacs 21 might miss this and that ...

I don't know whether you can explicitly restrict the replace-string 
function, but the simplest way to do what you want is with narrow-to-
region.

Go to the start of line 5 and C-space to set the mark and then go to
line 50 and C-x n n to call narrow-to-region. Emacs will warn you
you're doing something weird, so tell it that you really want to. Then
most of the buffer disappears, leaving just the stuff you want to
change.

Now replace-string just changes stuff in this region. To get back to
the whole file, you need C-x n w which calls "widen".

For getting to lines, M-g g is goto-line, which might help.

 From the doc string for replace-string in Emacs 22:

   In Transient Mark mode, if the mark is active, operate on the contents
   of the region.  Otherwise, operate from point to the end of the
   buffer.

So if region is visibly marked then the replace is only done in the 
region. (This is true if you use cua-mode for example.)
