tiniest

tiniest is a coreutils implementation that is as simple as possible. Who needs a --version flag on a simple pwd or clear command? Not me.

tiniest was made as a C++ learning project, is a WIP and should not be used in production as it purposely removes several features and in some places even basic error checking.

My goal is to add a new program to tiniest every day. This is imo a great way to learn.

Differences with GNU

Basically every command is different from GNU, but these differences were made on purpose, other than the -v and -h stuff:

• touch: only creates files
• yes: if argv[0] is no, output n instead of y
• chroot: use /bin/sh as def shell, use . as def dir
• clear: command originally from ncurses, not coreutils
• echo: does not allow any flags, just prints all arguments
• hostname: read src/hostname.cpp for info
• ls: currently does not have colors, with l totally diff format
• kill: originally not from coreutils but util-linux, SIGKILL by default, more into in src/kill.cpp
• realpath: uses . as the path if none specified
• cp: read src/cp.cpp

Building from source

We have a simple Makefile for compilation. It compiles every file in src/ as a separate program, and outputs it to bin/ (change with env: BIN_DIR). By defualt, it uses g++, but you can switch the compiler by changing the CXX enviroment variable, and you can change the flags with CXXFLAGS.

Start compilation:

make -j$(nproc)

Clean:

make clean
