Recursion in a bash script

So the problem I am having is recursion with in bash. Specifically the program ideally takes either the current or provided directory, lists out everything in that directory, if it finds another directory the script should call itself and go into that directory. I managed to get it to dive into the next working directory with this code:
Code:
list=`ls`
for l in $list
 if [ -d $l ] ; then
  cd $l
  echo "I'm in $l"
  dir=`pwd`
  cd ../
  bash script.bash $dir
 fi
done

My thinking proccess behind this was that it dives into that directory, states it's in there, gets the full path of that directory and stores it in a variable, get out of that directory to were the bash script is, then passes the created variable into the script. I was hoping that the bash script would then dive into the specified directory and do the same thing but it doesn't sadly.

ATF-SH(1)						    BSD General Commands Manual 						 ATF-SH(1)

NAME
atf-sh [-s shell] -- interpreter for shell-based test programs SYNOPSIS
atf-sh script DESCRIPTION
atf-sh is an interpreter that runs the test program given in script after loading the atf-sh(3) library. atf-sh is not a real interpreter though: it is just a wrapper around the system-wide shell defined by ATF_SHELL. atf-sh executes the inter- preter, loads the atf-sh(3) library and then runs the script. You must consider atf-sh to be a POSIX shell by default and thus should not use any non-standard extensions. The following options are available: -s shell Specifies the shell to use instead of the value provided by ATF_SHELL. ENVIRONMENT
ATF_LIBEXECDIR Overrides the builtin directory where atf-sh is located. Should not be overridden other than for testing purposes. ATF_PKGDATADIR Overrides the builtin directory where libatf-sh.subr is located. Should not be overridden other than for testing purposes. ATF_SHELL Path to the system shell to be used in the generated scripts. Scripts must not rely on this variable being set to select a specific interpreter. EXAMPLES
Scripts using atf-sh(3) should start with: #! /usr/bin/env atf-sh Alternatively, if you want to explicitly choose a shell interpreter, you cannot rely on env(1) to find atf-sh. Instead, you have to hardcode the path to atf-sh in the script and then use the -s option afterwards as a single parameter: #! /path/to/bin/atf-sh -s/bin/bash ENVIRONMENT
ATF_SHELL Path to the system shell to be used in the generated scripts. SEE ALSO
