UNIX-style core utilities for Windows. The same commands and pipelines you use on Linux, macOS, and WSL - natively.
Install · Shell conflicts · Windows caveats · Contributing
A Microsoft-maintained build of uutils/coreutils, findutils, and grep packaged as a single multi-call binary for Windows. The goal is to make moving between Linux, macOS, WSL, containers, and Windows frictionless: the same commands, flags, and pipelines work the same way, so existing scripts carry over without translation.
Each command supports the standard --help flag for full syntax and options.
This project is in preview.
Install
Install Coreutils for Windows with WinGet:
winget install Microsoft.Coreutils
Or grab the latest build from our Release Page.
Shell conflicts
Note
Any command not mentioned is included in this suite. The following only lists conflicts.
Warning
PowerShell 7.4 or newer is required. Older PowerShell versions aren't supported.
Several commands share names with built-ins in CMD and PowerShell. Whether the Coreutils version runs depends on the shell, the PATH order, and (for PowerShell) the alias table.

Windows caveats
| Difference | Detail |
|---|---|
| CRLF line endings | Windows text files often use CRLF (\r\n). Most utilities handle this transparently, but pattern matching with $ and exact byte counts can be affected. |
No /dev/null |
Use NUL instead, for example find . -name "*.log" > NUL |
| No POSIX signals | Signals such as SIGHUP, SIGPIPE, and SIGUSR aren't available. Ctrl+C (SIGINT) works as expected. |
| Path separators | Both / and \ are accepted. Some utilities produce \-separated output, which can affect downstream piping. |
| File permissions | Windows uses ACLs, not POSIX permission bits. Permission-based predicates (for example find -perm) may behave differently or be unavailable. |
| Symbolic links | Reading existing symbolic links works without elevation. Creating new symbolic links requires Developer Mode (Settings > System > Advanced) or an elevated terminal. |
PowerShell Command Parsing
The installer integrates itself with interactive PowerShell sessions via PSReadLine.
It ensures that quoted expression behave somewhat like they do under UNIX shells or CMD:
echo *.txt will then print a number of file names, while echo '*.txt' will print "*.txt" literally.
There are two shortcomings, however:
- PowerShell's escape character is still
`, not\
While you may writefind . \( -foo -bar \)with Bash, you still need to writefind . `( -foo -bar `)in PowerShell. Get-Command ls,Get-Help ls, etc., will still showls, etc., as builtin commands
Due to limitations aroundPSNativeCommandPreserveBytePipewe cannot integrate ourselves in a more robust way with PowerShell.
Intentionally dropped
Commands that exist upstream but aren't shipped here because they rely on POSIX-only concepts, would break existing Windows scripts, or simply aren't useful on Windows.
