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
Resultand? - Process control, exit codes, and CLI design
| 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).
