DOS script demonstration
One of the advantages of a command-line user interface is that one can combine several commands into a single script (a short, interpreted program). In DOS, these files have the extension .bat (batch).
The following is a listing of whatisintemp.bat, a file with a 5 command script:
c: (switch to drive C)
cd c:\temp (change to the directory c:\temp)
dir (list the contents of the dirctory)
echo that is all! (display "that is all!")
f: (switch back to drive F)
The comments in parenthisis are for clarification, and are not part of the batch file.
I put the file on a flash drive, drive F, opened a command window, switched to drive F, then typed the name of the file name (whatisintemp) to execute it. As you see here, the commands were executed in order. (I shortened the directory listing).
C:\USERS\LARRYP~1>f:
F:\>whatisintemp
F:\>c:
C:\Users\LARRYP~1>cd c:\temp
c:\temp>dir
Volume in drive C is OS
Volume Serial Number is 62AA-9AA9
Directory of c:\temp
