What are the default values for these export variables?

Question

I tried to setup sprof (following this http://greg-n-blog.blogspot.com/2010/01/profiling-shared-library-on-linux-using.html) using the below steps. Now my program won't run. What are the steps I need to do to undo the following?

2) export LD_PROFILE_OUTPUT=pwd
3) export LD_PROFILE=libmylib.so
4) rm -f $LD_PROFILE.profile

As per my knowledge, these steps have nothing to do with your program.

However, you can re-export the variables to undo the change as below:

export LD_PROFILE_OUTPUT=
export LD_PROFILE=

but you can not recreate the previous profile that you have removed by

rm -f $LD_PROFILE.profile

be sure that you replace libmylib.so with your library name.
