How can I create a Cygwin shortcut that will open Cygwin at a specific folder? This would obviate having to type
cd /cygdrive/c/Users/Tom/Desktop/
I have created the batch file and put it to the Cygwin's /bin directory. This script was developed so it allows to install/uninstall the registry entries for opening selected folders and drives in Cygwin. For details see the link http://with-love-from-siberia.blogspot.com/2013/12/cygwin-here.html.
update: This solution does the same as early suggestions but all manipulations with Windows Registry are hidden within the script.
Perform the command to install
cyghere.bat /install
Perform the command to uninstall
cyghere.bat /uninstall
