A Simple Implementation of Shell in C

LSH Shell

LSH is a simple implementation of a shell in C, and It demonstrates the basics of how a shell works. That is: read, parse, fork, exec, and wait. Since its purpose is demonstration (not feature completeness or even fitness for casual use), it has many limitations, including:

• Commands must be on a single line.
• Arguments must be separated by whitespace.
• No quoting arguments or escaping whitespace.
• No piping or redirection.
• Only builtins are: cd, help, exit.

Running

Use gcc -o lsh src/main.c to compile, and then ./lsh to run. If you would like to use the standard-library based implementation of lsh_read_line(), then you can do: gcc -DLSH_USE_STD_GETLINE -o lsh src/main.c.
