Even better solution: register a signal handler in your Bash session
for SIGHUP; the cygwin1.dll sends a hangup signal when CTRL_CLOSE_EVENT
is received. Something like this:
$ myclosefn() {
echo "My close func got called." > $HOME/myclosefn.txt
# TODO: add more clean-up logic here
}
$ trap myclosefn SIGHUP
I've tested this, so I know it works.
P.S. BTW, I didn't know the answer to this beforehand, but instead
actually looked at the source. That's one of the beauties of open
source projects: questions like these can be answered by direct
inspection. "Read the Source, Luke!" ;-)
