command to output a directory tree map

[TripleSix]

I need to make an output of a directory tree with all its files, something like this

map
|
+-- submap
|     |
|     +-- file1.ext
|     +-- file2.ext
|     +-- file3.ext
|
+-- submap
|
.

Is there a quick way to do something like this?

do
   if [ -d "$dir" ] ; then # ==> If it is a directory (-d)...
   zz=0                     # ==> Temp variable, keeping track of directory level.
   while [ $zz != $1 ]      # Keep track of inner nested loop.
     do
        echo -n "| "        # ==> Display vertical connector symbol,
                            # ==> with 2 spaces & no line feed in order to indent.
        zz=`expr $zz + 1`   # ==> Increment zz.
     done
     if [ -L "$dir" ] ; then # ==> If directory is a symbolic link...
        echo "+---$dir" `ls -l $dir | sed 's/^.*'$dir' //'`
        # ==> Display horiz. connector and list directory name, but...
        # ==> delete date/time part of long listing.
     else
        echo "+---$dir"        # ==> Display horizontal connector symbol...
        # ==> and print directory name.
        numdirs=`expr $numdirs + 1` # ==> Increment directory count.
        if cd "$dir" ; then          # ==> If can move to subdirectory...
          search `expr $1 + 1`       # with recursion ;-)
          # ==> Function calls itself.

if [ $# != 0 ] ; then
   cd $1 # move to indicated directory.

fi
echo "Initial directory = `pwd`"
numdirs=0
search 0
echo "Total directories = $numdirs"
exit 0
