It seems you are running bash through the old cygwin.bat, so you are using the Windows Console as terminal, and not through the default Mintty that is a more advanced Terminal.
By default Cygwin setup install the "Cygwin Terminal" entry in the windows menu
The content of the menu entry is like
C:\cygwin64\bin\mintty.exe -i /Cygwin-Terminal.ico -
with path like
C:\cygwin64\bin
These items can be a also recreated at the last step of cygwin setup running. There are two box entries :
□ Create icon on Desktop
□ Add icon to Start Menu
If you enable them, both will be recreated
