**Run Linux-style commands on Windows — natively, deterministically, with no VM and no WSL.**

fauxnix is a bash→PowerShell translation layer built for AI agents. Your agent keeps writing the bash it already knows (`ls -la | grep foo`, `find . -name '*.ts' | wc -l`, `kill -9 1234`), and fauxnix deterministically translates each command into PowerShell, executes it natively, and hands back output that looks like GNU/Linux: `ls -l` columns, bash-style error messages, coreutils exit codes, UTF-8/GBK handled automatically.

npm install -g fauxnix-cli    # then point any MCP harness at `fauxnix mcp`

$ fauxnix "cat nope.txt"
cat: nope.txt: No such file or directory        # not a PowerShell stack trace
