Linux Signals and Process Interruption

Introduction to Signals in Linux

• Linux processes can receive various signals.
• Signals are labeled with names starting with sig.

SIGINT Signal

• SIGINT (Signal Interrupt):
  • Used to interrupt a process.
  • Default action: terminate the process being interrupted.
  • Can be sent using the keyboard combination Ctrl + C.

Demonstration

• Example with pseudo parted:
  • Start a program, e.g., pseudo parted.
  • While in the parted tool, use Ctrl + C to interrupt.
  • The process is aborted, and control returns to the shell.

Key Points

• SIGINT is a useful signal for terminating processes in Linux.
• The process interruption can be done midway using Ctrl + C.
• Similar functionality to Windows process interruption.
