Is there a way to launch Emacs from terminal and execute some Emacs command automatically soon after Emacs is launched (the command to be executed inside of emacs is provided along with the Emacs-launching command executed from the shell.)
What I want to do exactly is to have a command to launch Emacs and then open a new empty buffer and activate org mode inside of this buffer.
I want something that might look like this
emacs -fs --command="evil-buffer-new && org-mode"
I want the -fs flag because I want Emacs to open in full-screen in this case.
Update
--eval flag didn't work. Forget about evil-buffer-new, I have tried something as simple as:
emacs --eval="(org-mode)" txt.txt
txt.txt is an empty text file created before executing the above command (and please don't ask me why I didn't use .org file extension).
after Emacs opened, org-mode wasn't active. I had to run pp-eval-expression then (org-mode) to activate it, and then it worked.
Am I missing something here? How about rephrasing the question like this:
How to open an empty text file (having .txt file extension) with Emacs from the terminal and have org-mode activated in that buffer automatically?
See C-hig (emacs)Action Arguments or even just run emacs --help -- there are several options for loading and evaluating arbitrary code.
--command="evil-buffer-new && org-mode"
More like:
--eval="(progn (evil-buffer-new) (org-mode))"
But you'll have to figure it out for yourself, because I don't know what evil-buffer-new is specifically.
You told an empty file is created before emacs is started. But instead of an empty file could you create a file with file-local mode variable specifying the org mode ? For example with bash:
#!/bin/bash
cat <<EOF >> "$1"
; -*- mode: Org;-*-
EOF
emacs "$1" &
Now the mode is always resolved correctly with normal major mode selection procedure.

I was setting up with emacs on my macbook. In order to open the emacs from command line, I was follow other's suggestion to add an emacs script to my /usr/bin.
Now I can open graphic emacs from command line, but the problem is that every time when I open the terminal, the emacs is automatic run. I don't know why this happened.
Here is the script I added:
#!/bin/sh
/Applications/Emacs.app/Contents/MacOS/Emacs "$#"
I also use chmod +x /usr/bin/emacs after the script was added.
Please tell me what cause the problem happens.
If your using the standard OS X terminal, look under preferences->profile and the shell tab and make sure there isn't something set in the run on startup option.
If your using another terminal, such as iTerm, check the profiles.
I have installed Emacs 24 on my Mac using homebrew, and similar to another question (listed below), I would like to use the same command when first starting Emacs as I do when opening additional files from the command line. To this end, I have set up an alias (modified a bit for readability):
EAPP=/usr/local/Cellar/emacs/24.3/Emacs.app/Contents/MacOS
alias emacs='emacsclient -a $EAPP/Emacs -n'
Here's the twist: I put the -n (same as --no-wait) at the end because I like not having to hit C-x # to finish buffers. A side effect that I like is that it returns immediately to the command line.
Could there be a way to alter my alias to make the first-time run go in the background as well? Or should I just teach my fingers to put a & after every invocation of my emacs alias?
Question about making emacs and emacsclient seem the same:
Emacs - connect to daemon (if it exists) without using emacsclient
I'm looking for a way to make the cygwin terminal more compact, or an alternate terminal that is more compact. Currently, every command I enter has a header line above it with username and pwd, and there is a blank line trailing every command. For instance:
username ~
$ cd tmp
username ~/tmp
$
3 lines for every 1 line of command. I frequently work on a small screen, which makes all this wasted space quite irritating. Is there a setting somewhere I can alter to prevent all this wasted space? Or, perhaps another terminal?
Thanks in advance.
That's the default shell prompt set by Cygwin.
To use a smaller prompt in your current terminal:
PS1='$ '
To make the change permanent, put that command in your ~/.bashrc file.
You can set the prompt to just about anything you like, as explained by the bash manual (there are several variables that control different prompts; $PS1 is the main one).
It's important to remember than in Cygwin (as in Linux and Unix), the terminal program is a separate program from the shell that runs in it. The prompt is controlled by the shell; bash is the default. The graphical display is controlled by the terminal emulator, which could be rxvt, mintty, xterm, or even the Windows terminal that normally runs a DOS-like shell.
What you're seeing there is the prompt, as stored in the environment variable PS1
echo $PS1
will show you how it's created. By the way, that prompt is managed by the bash shell, not by the terminal.
export PS1=$
will give you just a $ prompt
export PS1="$ "
will leave some room behind the prompt. There are many more possibilities, here is a nice tutorial.
bash reads its settings from a file called ~/.bashrc aka a file called .bashrc in your home directory. Note that due to the initial dot in the name ls won't show the file by default, ls -a or ls -la will.
I would Recommend we go with modern terminals using Cygwin-X as shown in the below interactive menu
I love Xfce Terminal which allows creating tabs and new windows with font options and color options
Suppose I am in terminal in Emacs (M-x term), and I list the following files in current directory:
text_code.R
Now I am in bash-3.2$ (terminal) and hope to open this .R file in another Emacs buffer and then edit. Is there a way to do it? This might be a trivial question, for I am a newbie to Linux and Emacs. Thanks in advance!
Remember that in Term Mode you can type C-c C-f to open a file (just like C-x C-f outside Term Mode). The prompt will already be on your current directory, so you just have to start typing the name of the file and autocomplete it with TAB.
I don't know the official procedure for what you want to do, but here is a procedure that works:
Either tell emacs to run as a daemon (Ref: EmacsAsDaemon) or in emacs start daemon via M-x server-start.
In the term, a command like emacsclient -n filename will start editing the specified file in the current window. Note, emacsclient also has a -c, --create-frame option to edit in a new frame. You probably will want to use a -n option as above, so you can continue using your term, after selecting it from the buffers list in another pane or frame.
If you start the daemon via M-x server-start in emacs, the daemon will terminate when you exit from emacs. If you set it up via reference mentioned above, use kill-emacs or save-buffers-kill-emacs commands or shell command emacsclient -e '(kill-emacs)' to stop it, as mentioned in part 6 of reference.
Often I find my self navigating the filesystem from a Conque shell in Vim and want to open a specific file inside my existing MacVim session. Is this possible ? - I was hoping for something like:
shell> open some/file.txt
and then have file.txt pop up inside my existing Vim window (preferably in a new tab).
Note: I am using #wycats vim dot files (not sure this matters).
Type from ConqueShell
mvim --remote-tab-silent filename
This will open the file in a new tab in MacVim
You could also write a Bash alias to shorten the command (assuming you are using bash).
Put in your ~/.profile
alias vim='mvim --remote-tab-silent'
this would enable you to type
vim filename
from ConqueShell or bash, and have it open in a new MacVim tab, rather than terminal vim. It of course does disable your ability to run standard vim (although you could still use the vi command), so maybe you would want to name the alias differently.
Just to add, this will work only if you placed the mvim executable on your path E.G. /usr/bin/mvim. It comes with the MacVim.app

The beauty of running a shell from inside vim is you have all of vim and the shell at your disposal.
gf is your friend. Once you get the file you want displayed on the screen in some way, you can enter normal mode, move the cursor to the file you want to edit, then use the gf command to navigate to the file. There are many ways to use this. Any program or command that outputs file names is great for this (ll, git status, etc). You could also type the filename into the shell, just to make it visible on the screen without actually running any terminal commands (tab completion is handy here).
It is possible, you can start vim as server and then add as many files as you want, but I'm not very familiar with this, so I can't give you just a direction.
