Minishell Project

$ Source Code

https://github.com/hekoh99/minishell

$ Overview

The Minishell project is a custom implementation of a Unix shell, similar to popular shells like zsh or bash. It supports several essential shell features, including redirection, piping, built-in commands, and signal handling. This shell allows users to execute commands, manage file redirection, and handle signals efficiently, simulating the behavior of a standard shell environment.

$ Features

• Redirection: Supports input/output redirection with <, >, and >> operators.
• Heredoc: Implements heredoc functionality using the << operator.
• Piping: Supports the | symbol for piping and parallel command execution.
• Built-in Commands: Implements five shell built-in functions:
  • echo
  • cd
  • pwd
  • env
  • exit
• Signal Handling: Processes signals such as:
  • Ctrl + C: Interrupts the running command.
  • Ctrl + \\\\: Quits the current process.

$ Example Usages

Here are some example commands to demonstrate Minishell in action:

# Example 1: Simple redirection
echo "Hello World" > output.txt

# Example 2: Append output using >>
echo "This will be appended" >> output.txt

# Example 3: Input redirection
cat < input.txt

# Example 4: Piping
ls -l | grep minishell

# Example 5: Heredoc
cat << EOF
This is a heredoc example
EOF

# Example 6: Using built-in commands
pwd
cd /path/to/directory
echo "Current path: $(pwd)"
env
exit
