In Linux, we can open a terminal and run a command by simply typing in the command's name. So, if I wanted to run DosBox, I'd just type: dosbox The $PATH environment variable is set to /bin,/sbin,/usr/bin,/usr/local/bin,/usr/local/games. And Linux looks in all of those directories for the executable. However, in Windows, one must type the full path of the executable. So, typing: C:\Program Files (x86)\DOSBox-0.74\DOSBox.exe would run DosBox. Is there an easy way to run programs from Command Prompt without having to type all of this?
