Yes, you are right. But to run a shell script you have to either quit
from gdb session or you have to run shell command to get a shell. In
first choice the analysis of debug information is offline that may not
be acceptable in certain situation where you take certain decision
based on your debug information. In second choice you every time get a
shell you source your shell profile (like bashrc bash_profile) that is
not acceptable.
Finally, the method you suggested will dump all the debug info in a
file (this sometimes annoying). Processing that big file will again
consumes more resources.
