You thought that a command line was a small black window with prompt line and blinking cursor, didn’t you?
As did I
Though I have used a command line from MS-DOS 6.0 where there was nothing except a command line to Windows XP that almost doesn’t have it.
A command line has undergone changes since MS-DOS and I didn’t suppose some of them.
So what do I mean?
Let’s carry out an experiment:
Run a command line (Start -> Run -> cmd.exe)
Execute some commands.
For example: netstat, ipconfig /all, arp -a and so on.
You probably know that you may choose previous/next commands pressing “Down Arrow”/”Up Arrow” key but I think you don’t surmise what happens when you press F7.
What does this hot key do in a command line?
Displays all commands stored in memory in a pop-up box. Use the UP ARROW key and the DOWN ARROW key to select the command you want, and press ENTER to run the command. You can also note the sequential number in front of the command and use this number in conjunction with the F9 key.
Deletes all commands stored in memory.
The buffer allows a maximum of 50 command lines. After this number is reached, the first line will be replaced in sequence.
What else hot key combinations are there in a command line?
