cygwin-portable-installer is a self-containing Windows batch file to perform an unattended installation of a portable Cygwin environment.

The installer has been implemented as a Batch script and not PowerShell script because in some corporate environments execution of PowerShell scripts is disabled for non-administrative users via group policies.

• portable: you can e.g. install it on an USB sticks and use the same configuration on different computers
• 256-color multi-tabbed shell: ConEmu incl. Cygwin Connector is pre-configured as terminal by default. Alternatively you can choose to use the single tabbed Mintty terminal.
• command-line package installer: apt-cyg package manager will be automatically installed
• adaptive Bash prompt: bash-funk will be automatically installed

1. Create a local empty directory where Cygwin shall be installed, e.g. C:\apps\cygwin-portable
2. Download the cygwin-portable-installer.cmd file into that directory.
3. (Optional) Open the file in an text editor and adjust the configuration variables to e.g. set an HTTP Proxy, change the set of pre-installed Cygwin packages, select the terminal (ConEmu or Mintty).
4. Execute the cygwin-portable-installer.cmd. This will automatically:
   1. download the 32 or 64bit Cygwin setup.exe depending on your OS,
   2. install Cygwin with the pre-selected set of packages,
   3. install the ConEmu tabbed terminal,
   4. create an init scripts that will keep the installation portable,
   5. install the apt-cyg command-line package manager.
   6. install the bash-funk Bash toolbox with it's adaptive Bash prompt.
5. Now you can launch your portable Cygwin environment using the newly created cygwin-portable.cmd batch file.
