Lightbulb Recursive function call problem
This is shell script I have made to lists out directory contents and filenames for any given directory (without using ls command). There is some problem in dirfunc function call which I have marked 1 is not working. Can anybody suggest what is the problem there and how should I correct it.

Code:
dirfunc()
{ path=$1/$2
  if test -d $path
  then
   echo "--------------------------------------------------------------------------------"
   dir=Sub-$3
   echo " $dir:   $path    "
   dir $path > inven
   declare -a no
   awk 'BEGIN{ t = 0}
     { { for(i=1 ; i<=NF ; i++)
      {
       no[t+$i] = $i
       dirfunc $path no[t+$i] $dir    _____________________(1)not working
      }
        t = t + NF
      }
    
     }' inven 
   echo "--------------------------------------------------------------------------------"
  else
   if test -f $path
   then
   echo "    $2   : File in $dir "
   fi
  fi
}

There are a couple of things I'm unfamiliar with here.
First of all -- my shell script doesn't have a "declare" command.

Secondly, if it did, I couldn't pass a variable into awk the way
you are doing in this script.

Why not do something like this:

find $dir_name -print

Are you looking for some special formatting?

Ah, you're trying to invoke a shell function from within awk. I'm sorry, that simply won't work. The best you could do, is define the shell function separately, put it in a RC startup file, create the awk command separately and put it in it's own file. Then the shell function invokes the awk script, and the awk command invokes the shell in such a way that the RC file is read, the function therefore loaded and executed.

But surely, there is a better approach to what you are trying to do. As quirkasaurus suggested, look up the find command.
