./init.sh: line 11: s:/programs/mongodb/mongodb/bin/mongod.exe --dbpath s:/programs/mongodb/data/ --repair: No such file or directory

Calling the printed command works fine:

s:/programs/mongodb/mongodb/bin/mongod.exe --dbpath s:/programs/mongodb/data/ --repair

Cygwin will actually do magic for you if you put your DOS paths in quotes, for example

cd "C:\Program Files\"

Cygwin does not recognize Windows drive letters such as s:, use /cygdrive/s instead. Your cygwin command should look like this:

/cygdrive/s/programs/mongodb/mongodb/bin/mongod.exe --dbpath s:/programs/mongodb/data/ --repair

Notice that the path like parameters you pass to the executable are in windows format as mongod.exe is not a Cygwin binary.

To make it easier, you could add mongod.exe your path, then you do not need to specify the directory it is in.
