info variables command
Dislays the list of global/static variables present in the debugged program
Syntax
info variables
info variables [Regex]

Parameters
- Regex
- If specified, the info variables command will list the global/static variables matching the regex. If omitted, the command wil list all global/static variables in all loaded modules (main program and shared libraries).
Examples
Below is a sample use of the info variables for a very basic program containing one global variable. Note that many variables (listed under "Non-debugging symbols" are implicitly defined by the compiler):
(gdb) info variables
All defined variables:
File test.cpp:
int g_GlobalVariable;
Non-debugging symbols:
