+Summary: You shouldn't need to run "file" before "attach" in mdb
+
+If you run mdb and then try to attach to an existing process, you'll get
+this error:
+
+ERROR: No executable file specified.
+Use the `file' command.
+
+Somehow gdb doesn't need this information to attach to native processes.
+
+Looking at various mono process in /proc/<pid>/fd, it looks like file
+descriptor 3 always contains the exe file I'm running:
+
+$ ls -l /proc/*/fd | grep "\.exe"

+mdb could look at that and extract the file to load automatically.
