Run Shell Command on Buffer

Run Shell Command on Buffer

[super-nub]

Hi!

1) Is it possible to run `shell-command' <some command> <RET> on the current
buffer? Or is there a shortcut to the file name of the current buffer, so
that I would type e.g. `ls -l %' as a command and % is replaced by the name
of the current file?

2) `fit-window-to-buffer' is cool :) Is it possible to fit another than the
currently active window to its buffer without switching to it?

Thx!

Have you checked shell-command-on-region?

What do you want to achieve?

Re: Run Shell Command on Buffer

Hi Pete,

for example I want to execute `grep' on my buffer/file to get a survey of the section headings in my document (that I keep in a special format for this purpose), e.g.:

$ egrep '^\s*-[[:upper:]]+' myfile
$ -INTRODUCTION
$     -BLA BLA
$     -BLA 2
$ -MAIN PART
$     -MISCELLANEOUS
$         -ETC BLA BLA

shell-command-on-region turned out to be a bit impractical, because I lose my current position in the document, as the cursor jumps to the beginning when running shell-command-on-region. I guess I would have to write a LISP macro to fix that...!?

Regards,
super-nub

It looks like `M-x occur' may be what you want.  It will display all the
hits in a separate buffer.

Another nifty aspect is that you can use the hits provided as links to
jump to them in the parent buffer.

If I understood your usage M-x occur will be just the ticket.

If you like this tool... type M-x occur<spc><spc> to see other
formulations of using it.

Yes, that is exactly it, thanks very much!

If you like `occur', you might also be interested in this page:

The mark-whole-buffer command (C-x h) pushes a mark at the original 
location.  So after you run shell-command-on-region, you can use C-u 
C-space C-u C-space to get back to where you were.

Wow, "occur" totally RULES! That's even more than I wanted to achieve!
:) Thanks!
The problem how to run an arbitrary shell command on the current file --
be it via the text in the buffer or via the filename -- remains. Any
ideas on that?

Whoops, sorry, replied to the wrong post...
C-u C-space is also quite handy, I will try to write a macro that automates
eveything, thx!

(buffer-file-name) ;; function

or

buffer-file-name  ;; variable

Re: Run Shell Command on Buffer

[scame]

That looks promising... is it possible to use the variable "inside"
shell-command? I'm thinking of something like

M-x shell-command <RET>
grep 'bla' $buffer-file-name

Thx,

Also, the next-error/previous-error commands, which work under
grep/occur/compilation modes, are very useful.  Try them.  I bind mine
to F6/F7:

(global-set-key [f6] 'next-error)
(global-set-key [f7] 'previous-error)

They will jump to the next/previous point of interest out of all the
grep/occur/compilation points of interest related to the current
buffer.

Drew: can you update the wiki with this info, or I'll do it?  Also,
can you check that your replace+.el (mentioned in the Emacs wiki)
works with next/previous error?

I think that is only the case for Emacs 22.

Done.

Yes, it works.

You're right, I forgot.  Sorry.
