I am writing a script which searching the given path(first parameter) and prints number of dirs, files etc.Update table is just a function which sorts my datas. My problem is how can i insert here the depth of searching. The depth will be the second parameter and the script will search my path until reach depth.
User will run the program as ./script.sh /Desktop/folder 2

What I have tried:

PowerShell

function check_dir {

      echo Checking dir : $1
           for f in `ls $1`
           do

            if [ -d $1/$f ]
           then

             dirs_num=$(($dirs_num+1))
             check_dir $1/$f

            else    

               files_num=$(($files_num+1))
               size=`stat -c%s $1/$f`
               echo $1/$f - $size
               update_table $1/$f $size
       
  fi

     done

}

    files_num=0
    dirs_num=0
    files_names=(a a a)
    files_sizes=(0 0 0)

    check_dir $1 

 echo Found $files_num files and $dirs_num dirs.

You just need to capture the depth value and reduce it by 1 each time you call check_dir. Something like:

JavaScript

function check_dir {
    depth = $($2 - 1) // reduce the depth count by 1
    echo Checking dir : $1
    for f in `ls $1`
    do
        
        if [ -d $1/$f ]
        then
        
            dirs_num=$(($dirs_num+1))
            if [ $depth -gt 0 ] // if the depth count is greater than 0
            then
                check_dir $1/$f  $depth// do a recursive check
            fi        
        else    
        
            files_num=$(($files_num+1))
            size=`stat -c%s $1/$f`
            echo $1/$f - $size
            update_table $1/$f $size
        
        fi
        
    done
    
}

NB apologies if some of my syntax is wrong, it's a few years since I was writing shell scripts.
