gdb Command Detailed

Awatch	Specifies a variable, if the variable is read or written, suspends the program, displays the information in the debugger, and waits for the next debug command. Refer to Rwatch and watch commands.
BackTrace	To display the trace of all stack frames (stack frames) and the value of the parameters of the current function called by the function, BT is the shorthand for this command.
Break	Set a breakpoint that specifies the line of code or function name as an argument
Clear	To delete a breakpoint, this command needs to develop a line of code or function name as an argument
Continue	Where the debugger stops, continue execution
Ctrl-c	Stops execution of executing program at current position, breakpoint on current line
Disable	Disable breakpoint feature, this command requires a forbidden breakpoint in the breakpoint list index value as parameter
Display	Displays the value of the specified expression where the breakpoint is stopped. (Show variables)
Enable	Allow breakpoint function, this command needs to allow breakpoints in breakpoint list index value as parameter
Finish	Continue execution, knowing that the current function returns
Ignore	Ignores the number of times a breakpoint has been set. Example: Ignore 4 23 ignores Breakpoint 4 's 23 run and interrupts at 24th time
Info Breakpoints	View breakpoint Information
Info display	View information about the expression that you want to display for your settings
Kill	Terminate the process of the current debug
List	Displays 10 lines of code. If no arguments are supplied to this command, 10 lines of code are displayed starting at the current line. If the function name is provided as an argument, it is displayed from the beginning of the function. If the number of the line of code is supplied as a parameter Number, this line is displayed as the beginning.
Load	Dynamically loads an executable file into the debugger.
Next	Executes all the instructions for the next line of source code. If it is a function call, it is also used as a line of source code to return to this function
Nexti	Executes an assembly instruction in the source code of the next line
Print	Display the value of a variable
PType	Display the type of a variable
Return	Force to return from the current function
Run	Execute from where the program started
Rwatch	Specifies a variable, if the variable is read, suspends the program, displays the information in the debugger, and waits for the next debug command. Refer to Rwatch and watch commands.
Set	Sets the value of a variable. For example: Set nval=54 will save 54 to the Nval variable
Step	Continue to execute all instructions for the next line of source code in the program. If you call a function, the command goes inside the function, stepping through the code in the function.
Stepi	Continue to execute the assembly instruction in the next line of the program's source code. If it is a function call, the command will go inside the function and step through the assembly code in the function.
Txbreak	Set a temporary breakpoint on the exit point of the current function (only once).
Undisplay	Deletes a variable display setting of display. This command requires an index in the display list to be an argument.
Watch	Specifies a variable, and if the variable is written, suspends the program, displays the information in the debugger, and waits for the next debug command. Refer to Rwatch and watch commands.
Whatis	Displays the value and type of the variable.
Xbreak	Sets a breakpoint on the point at which the current function exits.
