Tiny Shell

A minimalist shell implementation in C that supports basic input/output redirection and command piping.

Features

• Command execution with support for paths
• Input redirection using <
• Output redirection using >
• Command piping using |
• Background process execution with &
• Built-in quit command to exit the shell

Usage

# Build the shell
make

# Run the shell
./tsh

# Command line options
./tsh -h    # Display help message
./tsh -v    # Enable verbose mode
./tsh -p    # Disable command prompt

Examples

# Input redirection
❯ /bin/command < input.txt

# Output redirection
❯ /bin/command > output.txt

# Command piping
❯ /bin/command1 | /bin/command2

# Background execution
❯ /bin/command &

Limitations
