Want to launch a bash shell in any directory using the Windows Explorer context menu? This is how I did it, tweaking the basic method described here. This should work even for paths that have spaces or for UNC paths.
1. Edit Registry
– Start regedit.exe.
– Add these key/values:
HKEY_CLASSES_ROOTDirectoryshellBashHere=bash here
HKEY_CLASSES_ROOTDirectoryshellBashHerecommand=
cmd.exe /c C:cygwincygwin.bat "%1"
Note the quotation marks around „%1“.
Please adjust the path to cygwin.bat if necessary.
2. Edit cygwin.bat in c:/cygwin
This batch starts the bash shell with the last command line „bash…“.
Insert
set BASHHERE=%1
the line before.
This Environment variable now contains the complete path of the opened
folder and is available in the bash shell (echo $BASHHERE).
3. Edit profile
Make $BASHHERE the current directory by adding the following line to
/etc/profile or ~/.profile. (I’d replace your line cd „${HOME}“ with the following):
if [ "$BASHHERE" != "" ]; then
cd "$(cygpath -u "$(echo $BASHHERE | tr -d "42")")"
else
cd "${HOME}"
fi
The „tr -d“ deletes enclosing quotes, which cygpath can’t deal with for some reason when embedded in $BASHHERE. Maybe there’s a simpler way, but this way worked for me.
(For UNC paths, cmd.exe complains when you launch cygwin.bat, but it dutifully passes on the argument.)
