title: putting breakpoint in a file using "rbreak filename.c:." doesn't work
body: <p>I want to put breakpoint on all functions of a file. I came across this link : <a href="http://sourceware.org/gdb/download/onlinedocs/gdb/Set-Breaks.html#Set-Breaks" rel="noreferrer">http://sourceware.org/gdb/download/onlinedocs/gdb/Set-Breaks.html#Set-Breaks</a></p>
  
  <p>It suggest the use of rbreak command for this purpose. When i use "rbreak ." , it works fine as expected and puts breakpoint in all functions of a prog. But when is use </p>
  
  <p>rbreak filename.c:.</p>
  
  <p>This doesn't work at all and no breakpoint is put anywhere. I even tried a variation of this putting spaces around :, but even that doesn't work.</p>
  
  <p>Any idea on how this can be done ? Is it possible at all ? 
  Any help will be greatly appreciated.</p>
  
  <p>thanks,
  vikas</p>
