Tmux by tmux
tmux source code
About Tmux
From the project's README at github.com/tmux/tmux. Lightly cleaned for readability; for the full source see the upstream repo.
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.
To build tmux, a C compiler (for example gcc or clang), make, pkg-config and a suitable yacc (yacc or bison) are needed.
tmux can use the utempter library to update utmp(5), if it is installed - run configure with --enable-utempter to enable this.
