I have a bash script that runs screen and uses $( command ) to execute the output of command. I need to port this script to run on Windows. I installed Cygwin to run this but it doesn't recognize screen as a command and I don't know the Windows equivalent of linux's $(). Any suggestions on how to do this in windows?
screen is not installed by default.
You need to explicitly install it using cygwin setup.

$( command ) it is available in bash on Cygwin like on Linux
