Open Cygwin at a specific folder

Question

When you install Cygwin (or if you’ve already installed it, download it again and start setup again to run an update), make sure that you select the chere package under the "Shells" category.

After Cygwin is launched, open up a Cygwin terminal (as an administrator) and type the command: chere -i -t mintty -s bash.

Now you should have "Bash Prompt Here" in the Windows right-click context menu.

(mintty is Cygwin's default terminal. If you don't choose it with the -t option, your "Bash Prompt Here" will use the same terminal as the Windows Command Prompt, which prevents horizontal resizing.)

Here's what I use. It doesn't require chere package or registry tinkering. Works on Windows 7.

Go to your "Send To" folder:

C:\Users\<your_user_name>\AppData\Roaming\Microsoft\Windows\SendTo

Create a shortcut named Bash Here having this in the Target field:

C:\cygwin\bin\mintty.exe -i /Cygwin-Terminal.ico  C:\cygwin\bin\bash.exe  -l -c "cd \"$0\" ; exec bash"

In the Windows Explorer, you right-click on a folder & select Send To > Bash Here.

And here's the opposite trick, opening a Windows Explorer in your current bash dir. Create this alias:

alias winx='/cygdrive/c/Windows/explorer.exe /e,\`cygpath -w .\`'

Note: the cygpath -w . part above is enclosed in back-ticks.

Now just type winx at the bash prompt, and a Win Explorer pops up there.

Note: If winx directs you to your documents folder, try

alias winx='/cygdrive/c/Windows/explorer.exe /e,`cygpath -w $PWD`'

From the cygwin terminal, run this command:

echo "cd your_path" >> ~/.bashrc

The .bashrc script is run when you open a new bash session. The code above with change to the your_path directory when you open a new cygwin session.

I made a .reg file that puts an "Open Cygwin Here" option in the right-click context menu. It depends on the Cygwin "chere" package, which you can install using apt-cyg if you didn't install it in the initial setup.

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Directory\Background\shell\cygwin_bash]
@="Open Cygwin Here"

[HKEY_CLASSES_ROOT\Directory\Background\shell\cygwin_bash\command]
@="C:\\cygwin\\bin\\mintty.exe -e /bin/xhere /bin/bash.exe"

For cygwin64 or installations without chere you can use the following command in a registry entry (assuming windows due to your path, also assuming cygwin installation directory is c:\cygwin64)

C:\cygwin64\bin\mintty.exe /bin/sh -lc 'cd "`cygpath "%V"`"; bash'

Works on Windows 7 and 8 Registry file available for download here: http://tomkay.me/blog/Cygwin64---Open-Here-18
