FireCMD is a complete cmd replacement. We have still provided a way to execute the command line through command prompt. If you want a command to be executed by cmd.exe instead of FireCMD command interpreter, you can use the keyword "cmd:". The command should start with the "cmd:" keyword. It cannot be used anywhere in the middle of command string.
The following statement executes the dir and date commands of cmd.exe. The "cmd:" keyword can be useful while using command prompt's internal commands. Here, dir is actually an internal command of cmd.exe.
cmd:dir & date /T
Moreover, cmd.exe or any other shell can be nested inside FireCMD shell as shown in image below.
