Shell

tmux is a "terminal multiplexer", it enables a number of terminals (or windows) to be accessed and controlled from a single terminal. tmux is intended to be a simple, modern, BSD-licensed alternative to programs such as GNU screen.

This release runs on OpenBSD, FreeBSD, NetBSD, Linux, OS X and Solaris.

tmux depends on libevent 2.x. Download it from:

http://libevent.org

use this command to install it:

Choose Shell

$ sudo apt-get install libevent-dev

It also depends on ncurses, available from:

http://invisible-island.net/ncurses/

to install ncurse open shell and type:

$ sudo apt-get install libncurses5-dev libncursesw5-dev

To build and install tmux from a release tarball, use:

$ ./configure && make
$ sudo make install

tmux can use the utempter library to update utmp(5), if it is installed - run configure with –enable-utempter to enable this.

To get and build the latest tmux from version control:

	$ git clone https://github.com/tmux/tmux.git
	$ cd tmux
	$ sh autogen.sh
	$ ./configure && make

to run sh autogen.sh you need to install automake.

aclocal is part of the automake package.

$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get install automake

To install tmux run the following command:

$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get install tmux

To run tmux open shell and write:

tmux

see the tmux manual here tmux

and here tmux-cheatsheet

Tested on MacOs Catalina with tmux version 3.2a and emacs version 27.2

Copy/paste the below code at the end of your ~/.emacs.d init file Code from EmacsWiki

(require 'server)
    ;; some systems don't auto-detect the socket dir, so specify it here and for the client:
    (setq server-socket-dir "/tmp/emacs-shared")
    (server-start)

;; highlight-changes-mode is very handy when collaborating:
    (global-highlight-changes-mode t)
    ;; Keys for moving back and forth between changes, set these to what
    ;; you prefer:
    (global-set-key (kbd "<f5>") 'highlight-changes-previous-change)
    (global-set-key (kbd "<f6>") 'highlight-changes-next-change)
    (global-set-key (kbd "<f7>") 'highlight-changes-rotate-faces)
    (global-set-key (kbd "<f8>") 'highlight-changes-remove-highlight)

Now you need to create a new user if you dont have one already. To do this go to System Preferences-> Users and Groups. Create the user (you can use the default user).

Then create a group and name it as you wish. I will name it users for the example. The group will have as members the host (user1) and the users with whom you collaborate with.

Now go and create a directory tmux-shared in tmp location. Open terminal and use the bellow commands to create the directory (mkdir) tmux-shared, change a group of the directory (chgrp) and change file permission (chmod).

$ mkdir /tmp/tmux-shared
$ chgrp users /tmp/tmux-shared
$ chmod g+ws  /tmp/tmux-shared

Now its time to start the host using the below command:

Start up the host

$ tmux -S /tmp/tmux-shared/myshare

This will open tmux shell in /tmp/tmux-shared/myshare directory.

start up emacs as host:

$ emacs

Now start the server:

on emacs do M-x:server-start

Now open a new shell tab (cmd-d on mac) and try to connect to the host. Connecting to the host

Connecting to the host

$ tmux -S /tmp/tmux-shared/myshare

then do

$ emacsclient --tty --socket-name /tmp/emacs-shared/server

Well done! Have fun.

Watch the example below:

The Z shell (zsh) is a Unix shell […]. Zsh can be thought of as an extended Bourne shell with a large number of improvements, including some features of bash, ksh, and tcsh¹

Some Linux systems come preloaded with zsh. You can check if it exists as well as its version by writing zsh –version in a terminal window. In case this zsh version is ok for you, you're done now!

Determine on which Linux distribution your system is based on. See List of Linux distributions – Wikipedia for a list. Most Linux systems – including Ubuntu – are Debian-based.

Debian-based linux systems

Open a terminal window. Copy & paste the following into the terminal window and hit Return. You may be prompted to enter your password.

Choose Shell

$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get install zsh

You can use zsh now.

to switch from bash to zsh open shell and run the following command:

$ chsh -s $(which zsh)

To know which shell are you using, use the following command:

$ echo $SHELL

It will return something like:

/bin/bash

or

/bin/zsh

After you know the shell, if the file .bashrc or .zshrc doesn't exist in your home directory (echo $HOME to find out), just create it.

If you are using bash, you may have a file called .bash_profile where you can put your export command instead (don't know in zsh).

Choose Shell

install ffmeg

$ brew install ffmpeg --with-fdk-aac --with-ffplay --with-freetype --with-libass --with-libquvi --with-libvorbis --with-libvpx --with-opus --with-x265

link brew with python

brew link python

remove existed files

rm 'usr/local/Cellar/2to3'

convert .m4a to .wav

$ ffmpeg -i /Users/sounds/23.3.\ j.m4a  23.3.\ j.wav

convert all the files into directory with .wma to mp3

$ for file in *.wma; do ffmpeg -i "${file}"  -acodec libmp3lame -ab 192k "${file/.wma/.mp3}"; done
