Yes they are case sensitive.. :-)
Yes. Just about everything to do with Linux on the command line is case sensitive, including commands and file names.
You can view the history of commands entered on a Linux system with the history command.
The history command displays all commands that have been entered into the terminal.
You get a command not found. Linux is case sensitive. So, for example: The command "systemctl" will not be the same as "SystemCTL" to a shell in Linux. One will work, the other will return an error saying there's no such command.
k is not a standard command in Linux.
There is no such command. Obviously, in order to enter a command into the prompt, Linux must already be on.
You can easily cycle through previously entered commands by pressing the Up key.
In a Linux terminal, the command to create a new directory is: mkdir .
In Linux the chmod command is used to set file permissions.
Nothing. Helo is not a recognized command in linux.
Linux does not have a limit as to the number of characters you can enter in a command.
