I used to launch latex within Emacs on a .tex file by C-c C-c.
I just changed my machine, and need to reconfigure all. I have already installed texlive-full, and copied .emacs from the previous machine to the new machine.
When I open a .tex file under Emacs, launch C-c C-c, and then type LaTeX, it opens another buffer, named *tex-shell*, and looks like as so:
Could anyone tell me what happened?
I don't really now what happen, but it seem you want to use auctex:
sudo apt-get install auctex
and relaunch Emacs should solve your problem.

I just installed Emacs 26.3 on Ubuntu 20.04. I opened a buffer in the terminal, and I cannot close it. C-x C-c does nothing. f10 to activate the menu does not activate the menu.
I'm using a .emacs file that maps cut/copy/paste commands to the normal C-x/C-c/C-v. I don't think that this can affect the issue, however, because I have the exact same setup (including the same .emacs file) on by Emacs 24.5/Ubuntu 16.04 laptop, and it has no problem exiting with C-x C-c. Also, I had the exact same problem before I installed the .emacs file on the new system.
How do I kill Emacs?
This question exists, but it has no useful answers.
ESC x save-buffers-kill-terminal
OFC binding C-x will affect C-x C-c. You don't need to know anything about Emacs to realize the problem. Just think twice.
I'm using emacs -nw (Emacs 24.5, Ubuntu 16.04). And I found that the default emacs M-w C-y keys don't work interchangeably with the operating system.
After some research, it seems that the most comprehensive solution is to use simpleclip. EmacsWiki says that
simpleclip
You can use https://github.com/rolandwalker/simpleclip which ALWAYS
works.
But looking into its usage guide above, simpleclip makes use of a set of keys that are completely different from the default M-w C-y or the OS Ctrl-Shift-c, Ctrl-Shift-v for copy-paste
;; Press super-c to copy without affecting the kill ring.
;; Press super-x or super-v to cut or paste.
I don't really want to use super key a lot with my PC keyboards, and don't want to remember (or persuade others to remember) yet another set of copy-paste keys.
For the GUI emacs, I can copy something in emacs and paste it into another terminal without any configuration. Mostly, I don't feel that Emacs is any different from gedit except that the emacs copy-paste keys M-w C-y can be used in addition.
In the terminal mode, most of it breaks down. If I use OS copy (Ctrl-Shift-c), one line in emacs can be copied into two or more lines in a target terminal because the line is too long. contents copied using M-w simply do not paste into other programs, even though I tried to set certain variables following other SO questions, e.g.:
(setq x-select-enable-clipboard t)
I'm not very familiar with elisp. My question:
How can I customize or configure simpleclip so that copy-paste in emacs -nw is exactly the same as copy-paste in the OS?

I recommend you use the xclip package, which you can install from GNU ELPA (i.e. via M-x package-list-packages). It requires installation of the xclip utility under X11 (e.g. via aptitude install xclip) and uses the pbcopy/pbpaste under macOS.
I want to use the command C-c C-x C-l to preview latex code in org-mode. Since the emacs-nox cannot do this, I tried apt-get install emacs24. However, after I have installed the emacs24 with GUI, I get an error like
can't find \`latex'(needed to convert LaTeX fragments to images)
I have installed texlive2016, and I can latex *.tex in shell command.
I added the /paht/to/latex to .emacs, but it don't work well.
Adding the following to my init.el makes it work:
;; Making emacs find latex (so that C-c C-x C-l works on orgmode)
(setenv "PATH" (concat ":/Library/TeX/texbin/" (getenv "PATH")))
(add-to-list 'exec-path "/Library/TeX/texbin/")
It is not a very pretty solution, but it does the job and is very easy to modify and understand.
This solution worked on a Mac running macOS Sierra and Emacs v25.1.
My crystal ball tells me that the problem is that you're not starting the GUI Emacs from a terminal, so it can't inherit your $PATH settings. See for example https://emacs.stackexchange.com/questions/10722/ (that question is within OSX, but the same problem appears in other systems).
Apparently you can set env-vars globally (so that they affect all applications, including those started directly from the GUI) in ~/.pam_environment (that's for GNU/Linux systems). Note that this is only consulted when you login, so you need to logout+login for changes to take effect.
I'm trying to install Emacs via Homebrew. Having done this and aliased to my apps folder, I found that when I ran Emacs it came up Spacemacs. I did them remember the system had Spacemacs installed a few years ago. So, I uninstalled Emacs, removed the emacs folders. Now, Homebrew shows no installation of Emacs. However, when I run emacs in the terminal, I still get Spacemacs.
How do I completely remove Spacemacs so I can install "vanilla" Emacs?
I thought I'd look at where Spacemacs is installed and did a "whereis emacs", but nothing but the prompt was returned.
Remove or rename ~/emacs.d folder. Spacemacs is not a different emacs, it's a different way of initializing emacs. The initialization files are in ~/emacs.d.
I realised that Spacemacs was a layer of Emacs. I needed to delete the .spacemacs folder in my user directory. Once done Emacs showed up as vanilla.
To completely remove emacs, I also searched for "emacs" and it found some folders in various bin directories. Once all of this was removed my system was ready for a vanilla emacs installation.
First, check where your emacs loads its configurations. Probably from ~/.emacs.d.
Then, remove the folder or just rename it.
Finally, restart emacs
As of spacemacs, there is another file named .spacemacs, it usually dwells in your home folder. If you remove/rename ~/.emacs.d and do nothing about .spacemacs,emacs will not read .spacemacs.
I want to keep emacs open most of the time, and then whenever I open a text file, python file, etc (from nautilus/finder), I want it to open as a new buffer in my current emacs instance, rather than starting a new instance.
I tried following this guide:
I wasn't really sure about what to do with the file, but what I tried was copying it to /usr/bin/emacs_openfile, adding #!/bin/sh to the first line, and running chmod +x emacs_openfile
However, it doesn't work for me and just opens a new instance, even though I was able to associate text files with this program.
On a sidenote, I set emacs as the default editor using this.
You want emacs client.
Basically, set emacsclient as your default editor, and add (server-start) somewere in your emacs config.
There needs to be a running Emacs instance for emacsclient to work, but if it's a hassle it's possible to have a headless Emacs launched at login.
Did you start server in emacs? Make sure that you add (server-start) to your .emacs or do M-x server-start from an existing EMACS session.
Conceptually, it's really easy, just do emacsclient file-name on the command line or where you name the program.
Just for your information, If you are using GUI version on Mac, the dir os emacsclient is below:
/Applications/Emacs.app/Contents/MacOS/bin/emacsclient
