What is debugging how is GDB tool helpful to find the bugs in Linux programming?

GNU Debugger or GDB: A Powerful Source Code Debugging tool for Linux Programs. GNU Debugger, also known as gdb, allows us to sneak through the code while it executes or what a program was trying to do at the moment before it crashed. GDB basically helps us to do four main things to catch flaws in the source code.

Is a debugger used in software development?

When the bug is fixed, then the software is ready to use. Debugging tools (called debuggers) are used to identify coding errors at various development stages. They are used to reproduce the conditions in which error has occurred, then examine the program state at that time and locate the cause.

What is tool for debugging a Linux kernel?

Kgdb is intended to be used as a source level debugger for the Linux kernel. It is used along with gdb to debug a Linux kernel. The expectation is that gdb can be used to “break in” to the kernel to inspect memory, variables and look through call stack information similar to the way an application developer would use gdb to debug an application.

What is the difference between debugger and compiler?

The main difference between compiler and debugger is that compiler converts the source code to equivalent machine code to execute the tasks defined in the program while debugger helps to recognize the errors of a program and to fix them. Generally, a computer program is a set of instructions that instructs the CPU to perform a certain task.
