U404 Shell

U404 Shell is a lightweight command-line shell written in Rust. It provides basic file system commands and simple scripting capabilities.

Features

• File operations: select, delete, create
• Directory creation
• System utilities: list files, display the current directory, clear the screen
• Script execution from a file
• Conditional execution with if, else and endif
• Math helpers: random number generation via random and square root calculation via math.sqrt

Command Reference

delete	Delete the selected file

Scripting

Scripts are plain text files containing one command per line. Conditional execution is supported using if, else and endif statements.

Example script.txt:

if file_exists test.txt
    uprint File exists
else
    uprint File does not exist
endif

Run the script with:

execute_script script.txt

Building

cargo build --release

Running

cargo run --release -- [script]

Running without arguments starts an interactive REPL.
