42SP 8th common-core project, minishell is a shell that aims to reproduce most of bash's behaviors.

git clone git@github.com:iuryr/minishell.git minishell
cd minishell
make
./minishell

dependency: GNU readline library (https://directory.fsf.org/wiki/Readline#tab=Overview)

• Input redirection: cat < file.txt)
• Here-documents: cat << eof, then input as many lines as you want. End input with a line containing 'eof' (the delimiter we set earlier) or CTRL+D;
• Output redirection: echo arg1 arg2 > output.txt and echo arg3 >> output.txt
• Pipelines: cat Makefile | grep CC | wc -l
• Environment Variables: export VAR=value
• Working prompt history
• Bashes exit status: echo $?
• Signal handling similar to bash
• The following builtins: echo, cd, pwd, export, unset, env, exit
• Double quotes preserves variable expansion, single quotes prevent variable expansion.
