# Shell & OS Rules - Always use bash/sh syntax for terminal commands, never PowerShell - Use `cp` instead of `Copy-Item` - Use `mv` instead of `Move-Item` - Use `rm` instead of `Remove-Item` - Use `mkdir -p` instead of `New-Item -ItemType Directory` - Use `cat` instead of `Get-Content` - Use forward slashes `/` in paths, never backslashes `\` - Do not use `$env:` for environment variables, use `$VAR` syntax
