All three are end/terminate process runs.

1.SIGINT sigterm Difference

The former is associated with the character Ctrl + C, which does not have any control character associations.

The former can only end the foreground process, while the latter is not.

The difference between 2.SIGTERM Sigkill

The former can be blocked, processed, and ignored, but the latter cannot. The signal sent by default without parameters for the KILL command is Sigterm. Let the program have a good exit. Because it can be blocked, some processes cannot be ended with kill to send the latter signal. That is: the kill-9 process number.
