#Shell

Setting up a new Mac took 2 days. With dotfiles and automation scripts, it now takes 30 minutes to get a fully configured dev environment.

I wasted 50% of my disk space because I didn't know the difference between Copy and Link. Deep dive into Inode, the secret of `rm` command, and why `pnpm` is faster than `npm`.

Shell is not the core of OS. It's just a 'Messenger' passing user commands to Kernel. The real role of zsh and bash.
