You can get online help from @value{GDBN} itself +by using the command @code{help}. + +You can run @code{gdb} with no arguments or options; but the most +usual way to start @value{GDBN} is with one argument or two, specifying an +executable program as the argument: + +@smallexample +gdb program +@end smallexample + +You can also start with both an executable program and a core file specified: + +@smallexample +gdb program core +@end smallexample + +You can, instead, specify a process ID as a second argument, if you want +to debug a running process: + +@smallexample +gdb program 1234 +@end smallexample + +@noindent +would attach @value{GDBN} to process @code{1234} (unless you also have a file +named @file{1234}; @value{GDBN} does check for a core file first). + +Here are some of the most frequently needed @value{GDBN} commands: + +@c pod2man highlights the right hand side of the @item lines. +@table @env +@item break [@var{file}:]@var{functiop} +Set a breakpoint at @var{function} (in @var{file}). + +@item run [@var{arglist}] +Start your program (with @var{arglist}, if specified). + +@item bt +Backtrace: display the program stack. + +@item print @var{expr} +Display the value of an expression. + +@item c +Continue running your program (after stopping, e.g. at a breakpoint). + +@item next +Execute next program line (after stopping); step @emph{over} any +function calls in the line. + +@item edit [@var{file}:]@var{function} +look at the program line where it is presently stopped. + +@item list [@var{file}:]@var{function} +type the text of the program in the vicinity of where it is presently stopped. + +@item step +Execute next program line (after stopping); step @emph{into} any +function calls in the line. + +@item help [@var{name}] +Show information about @value{GDBN} command @var{name}, or general information +about using @value{GDBN}. + +@item quit +Exit from @value{GDBN}. +@end table + +@ifset man +For full details on @value{GDBN}, +see @cite{Using GDB: A Guide to the GNU Source-Level Debugger}, +by Richard M.
