Piped insert-file?

Piped insert-file?

[ginak]

Is there a way (without creating a temporary file) to insert into a
buffer the results of running a file's contents through a Unix pipe?

Thanks,

C-u M-! and C-u M-| will execute commands and insert the output in the
current buffer.  The second command pipes the current region to the command
and replaces it with the output.

Some more words would be helpful. you can run
M-x shell-command-on-region 

line-1
line-2
line-4
line-10
line-5

Making it in a region and run sort on it yields
line-1
line-10
line-2
line-4
line-5

other option you may have run
(shell-command-to-string "ls -l /tmp/*")
C-u C-x C-e insert that stuff at point here

If you want it interactive you have to write a wrapper for it and than
there is with-output-to-temp-buffer which may of some use too

Thanks.  That's great to know.

When I tried C-u M-! with "grep foo foo_file", I got the desired text
inserted in the buffer, but preceded by the lines:

stty: standard input: Inappropriate ioctl for device
stty: standard input: Inappropriate ioctl for device

I don't know how to interpret these lines.

These are typically messages due to your running `stty' from your
shell startup scripts even if the shell is not run interactively.

The elisp code for the M-! function has the following to say about it:

	    ;; We do not use -f for csh; we will not support broken use of
	    ;; .cshrcs.  Even the BSD csh manual says to use
	    ;; "if ($?prompt) exit" before things which are not useful
	    ;; non-interactively.  Besides, if someone wants their other
	    ;; aliases for shell commands then they can still have them.

Your shell startup file (.cshrc, .bashrc, .kshrc, whichever is appropriate
for your shell) contains stty commands, which should only be done in
interactive shells (in fact, probably only in the initial login shell, so
they should probably be in .login or .profile).
