    tmux

    tmux

    tmux is a terminal multiplexer

    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, OS X and Solaris. tmux depends on libevent 2.x, and on ncurses. To build tmux, a C compiler (for example gcc or clang), make, pkg-config and a suitable yacc (yacc or bison) are needed. Some platforms provide binary...

    Compile and execute C "scripts" in one go!

    I love C for its raw speed (although it does have its drawbacks). We should all write more C. With this shell script, you can compile and execute C "scripts" in one go! (Oh yeah, and it works for C++ too.) First of all, I want to clarify why this is not the same as tcc -run. TCC is a compiler. We all know that. TCC will perform its own set of optimizations, just as GCC will perform its own and Clang will perform its own. The purpose of this script is to give a simple front-end to your...
