Start bash shell (cygwin) with correct path without changing directory

Question

I need to run a cygwin shell script without changing the working directory, from outside the cygwin environment.

If I run just \path\to\bash.exe -c command, then the path is not set correctly and cygwin programs can't be found.

If I use the --login option, bash sets the path correctly, but also changes to my home directory.

What options should I use to launch bash to keep the current working directory, and also find cygwin executables?

Answer 1

It turns out that the cygwin default /etc/profile checks for an environment variable named CHERE_INVOKING and inhibits the change of directory if set.

So

set CHERE_INVOKING=1
\path\to\bash.exe -l -c command

has the desired behavior.
