🦀 rust-cli-tools

A hands-on educational project reimplementing classic Unix command-line tools in Rust — to learn:

• File I/O & system calls (std::fs, std::io)
• Manual argument parsing (no external crates)
• Robust error handling with Result and ?
• Process control, exit codes, and CLI design

🛠 Implemented Commands ✅

Command	Features
echo	-n, --no-newline
cat	concatenate files, read from stdin (-), basic error handling
stat	display file type, size, permissions, owners, modified date, etc...
pwd	print working directory
mkdir	create directories (mkdir dir1 dir2)
rmdir	remove empty directories
mv	move/rename files and directories
ln	create hard links and symbolic links
head	print first 10 lines of a file
date	print current date/time
env	print environment variables

📌 All tools exit with proper status codes and print helpful errors (no panic! on user mistakes).
