Executing a CLI command from Python

Executing a CLI command from Python

[Paul Koning]

I looked through the Python GDB API documentation but didn't see this: is there a way for Python code to ask GDB to execute a command?

For example, I want to look up information about a kernel module (addresses etc.) then issue an "add-symbol-file" command using parameters constructed from what was looked up.

I think this can be done with gdb.execute ():

Sure looks like it.  Thanks Jan.  I didn't think to look in "basic" for that feature.

I looked through the Python GDB API documentation but didn't see this: is there a way for Python code to ask GDB to execute a command?

For example, I want to look up information about a kernel module (addresses etc.) then issue an "add-symbol-file" command using parameters constructed from what was looked up.
