Once started, it reads -commands from the terminal until you tell it to exit with the GDB -command \c -.B quit\c -\&. You can get online help from \c -.B gdb\c -\& itself -by using the command \c -.B help\c -\&. - -You can run \c -.B gdb\c -\& with no arguments or options; but the most -usual way to start GDB is with one argument or two, specifying an -executable program as the argument: -.sp -.br -gdb\ program -.br -.sp - -You can also start with both an executable program and a core file specified: -.sp -.br -gdb\ program\ core -.br -.sp - -You can, instead, specify a process ID as a second argument, if you want -to debug a running process: -.sp -.br -gdb\ program\ 1234 -.br -.sp - -would attach GDB to process \c -.B 1234\c -\& (unless you also have a file -named `\|\c -.B 1234\c -\&\|'; GDB does check for a core file first). - -Here are some of the most frequently needed GDB commands: -.TP -.B break \fR[\|\fIfile\fB:\fR\|]\fIfunction -\& -Set a breakpoint at \c -.I function\c -\& (in \c -.I file\c -\&). -.TP -.B run \fR[\|\fIarglist\fR\|] -Start your program (with \c -.I arglist\c -\&, if specified). -.TP -.B bt -Backtrace: display the program stack. -.TP -.BI print " expr"\c -\& -Display the value of an expression. -.TP -.B c -Continue running your program (after stopping, e.g. at a breakpoint). -.TP -.B next -Execute next program line (after stopping); step \c -.I over\c -\& any -function calls in the line. -.TP -.B step -Execute next program line (after stopping); step \c -.I into\c -\& any -function calls in the line. -.TP -.B help \fR[\|\fIname\fR\|] -Show information about GDB command \c -.I name\c -\&, or general information -about using GDB. -.TP -.B quit -Exit from GDB. -.PP -For full details on GDB, see \c -.I -Using GDB: A Guide to the GNU Source-Level Debugger\c -\&, by Richard M.

Many options have -both long and short forms; both are shown here. The long forms are also -recognized if you truncate them, so long as enough of the option is -present to be unambiguous. (If you prefer, you can flag option -arguments with `\|\c -.B +\c -\&\|' rather than `\|\c -.B \-\c -\&\|', though we illustrate the -more usual convention.) - -All the options and command line arguments you give are processed -in sequential order.
