how can i avoid retyping the same thing repitiously in gdb?

I have a lengthy program with several variables i want to check up on periodically. rather than typing 

print var1 
print var2
print var2

and so on, ho can I either get output for multiple variables from one print (I tried print var1, var2, var3 but that didn't work.)

or

How can I write my own function to do the same thing as repetitiously typing print for each available?

is there any easier way?

Solution

  • You were close enough

    print (var1, var2, ...)

    Incidentally, you can use p as a shorthand for print:

    p (var1, var2, ...)

    If you simply want to monitor those variables for changes, then you need to watch them:

    watch var1
watch var2

    This way, any time the value of var1 etc. changes, GDB will notify you and print old and new value.
