README excerpt
Welcome to tmux! tmux is a terminal multiplexer: it enables a number of terminals to be created, accessed, and controlled from a single screen. tmux may be detached from a screen and continue running in the background, then later reattached. This release runs on OpenBSD, FreeBSD, NetBSD, Linux, macOS and Solaris. * Dependencies tmux depends on libevent 2.x, available from: https://github.com/libevent/libevent/releases/latest It also depends on ncurses, available from: https://invisible-mirror.net/archives/ncurses/ To build tmux, a C compiler (for example gcc or clang), make, pkg-config and a suitable yacc (yacc or bison) are needed. * Installation 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 from version control - note that this requires autoconf, automake and pkg-config: $ git clone https://github.com/tmux/tmux.git $ cd tmux $ sh autogen.sh $ ./configure && make $ sudo make install * Contributing Bug reports, feature suggestions and especially code contributions are most welcome.
