Dear Cygwin users,
I have several Cygwin installation for different purposes (think of it as light weight VMs). I observe an unexpected behavior of ~ when I call a bash from one Cygwin from a bash of another Cygwin. The procedure is as follows:
* I have a Cygwin in C:\bin\cygwinA
* I start a bash via C:\bin\cygwinA\cygwin.bat
* From this bash I start DOS batch file which first sets up a new Cygwin under C:\bin\cygwinB with a well-defined set of packages
* The same batch file then starts a bash from CygwinB via C:\bin\cygwinB\bin\bash --login /cygdrive/c/bin/cygwinB/somefolder/somescript.sh
When I dump various paths from somescript.sh I get:
* echo "$(cygpath -a -w /)" => C:\bin\cygwinB
* echo "$(cygpath -a -w .)" => C:\bin\cygwinA\home\<user>
* echo "$(cygpath -a -w ~)" => C:\bin\cygwinA\home\<user>
The first two are expected, but the last one is unexpected. I would have expected C:\bin\cygwinB\home\<user>. I don't understand why / is in cygwinB but ~ in cygwinA.
Best regards,
Michael
