    ConEmu - Handy Console Window

    ConEmu - Handy Console Window

    Local Terminal Emulator

    ConEmu-Maximus5 aims to be handy, comprehensive, fast and reliable terminal window where you may host any console application developed either for WinAPI (cmd, powershell, far) or Unix PTY (cygwin, msys, wsl bash). As Windows console window enhancement (local terminal emulator), it presents multiple consoles and simple GUI applications as one customizable tabbed GUI window with various features. Also, due to deep integration, ConEmu is the best companion for Far Manager, my favorite shell replacement. Disclaimer. ConEmu is not a shell, so it does not provide "shell features" like tab-completion, command history and others. But you can run any shell or remote access client of your choice in ConEmu! Try Clink for bash-style completion in cmd.exe and PSReadLine or PowerTab in powershell.exe. Or just run Bash from your favourite distro. Also, ConEmu does not provide remote access (SSH/Telnet/...) too, just use your remote client (ssh.exe, telnet.exe) instead.
