Search for a task ("list files", "copy", "grep") or a command name and see
the closest equivalent across Bash/Linux, PowerShell, and Windows CMD side by side — with the
real differences called out, not glossed over. A lot of these are "closest equivalent," not
"identical command": PowerShell pipes objects instead of text, CMD's del can't
remove directories, chmod/chown have no true Windows equivalent
because NTFS uses a completely different permission model. Nothing here executes
anything — this is a reference, not a shell. Runs entirely in your browser.
A note on scope
This covers the commands people actually reach for constantly during day-to-day admin,
troubleshooting, and scripting work across the three platforms — not an exhaustive list of
every CLI tool on either OS. Where there's genuinely no equivalent (Windows has nothing like
chmod's permission bits), that's stated plainly instead of pointing at something
superficially similar that behaves differently.
