bash check for subdirectories under directory - bash

Question

This is my first day scripting, I use linux but needed a script that I have been racking my brain until i finally ask for help. I need to check a directory that has directories already present to see if any new directories are added that are not expected.
Ok I think i have got this as simple as possible. The below works but displays all files in the directory as well. I will keep working at it unless someone can tell me how not to list the files too | I tried ls -d but it is doing the echo "nothing new". I feel like an idiot and should have got this sooner.
#!/bin/bash
workingdirs=`ls ~/ | grep -viE "temp1|temp2|temp3"`
if [ -d "$workingdirs" ]
then
echo "nothing new"
else
echo "The following Direcetories are now present"
echo ""
echo "$workingdirs"
fi

If you want to take some action when a new directory is created, used inotifywait. If you just want to check to see that the directories that exist are the ones you expect, you could do something like:
trap 'rm -f $TMPDIR/manifest' 0
# Create the expected values. Really, you should hand edit
# the manifest, but this is just for demonstration.
find "$Workingdir" -maxdepth 1 -type d > $TMPDIR/manifest
while true; do
sleep 60 # Check every 60 seconds. Modify period as needed, or
# (recommended) use inotifywait
if ! find "$Workingdir" -maxdepth 1 -type d | cmp - $TMPDIR/manifest; then
: Unexpected directories exist or have been removed
fi
done

Below shell script will show directory present or not.
#!/bin/bash
Workingdir=/root/working/
knowndir1=/root/working/temp1
knowndir2=/root/working/temp2
knowndir3=/root/working/temp3
my=/home/learning/perl
arr=($Workingdir $knowndir1 $knowndir2 $knowndir3 $my) #creating an array
for i in ${arr[#]} #checking for each element in array
do
if [ -d $i ]
then
echo "directory $i present"
else
echo "directory $i not present"
fi
done
output:
directory /root/working/ not present
directory /root/working/temp1 not present
directory /root/working/temp2 not present
directory /root/working/temp3 not present
**directory /home/learning/perl present**

This will save the available directories in a list to a file. When you run the script a second time, it will report directories that have been deleted or added.
#!/bin/sh
dirlist="$HOME/dirlist" # dir list file for saving state between runs
topdir='/some/path' # the directory you want to keep track of
tmpfile=$(mktemp)
find "$topdir" -type d -print | sort -o "$tmpfile"
if [ -f "$dirlist" ] && ! cmp -s "$dirlist" "$tmpfile"; then
echo 'Directories added:'
comm -1 -3 "$dirlist" "$tmpfile"
echo 'Directories removed:'
comm -2 -3 "$dirlist" "$tmpfile"
else
echo 'No changes'
fi
mv "$tmpfile" "$dirlist"
The script will have problems with directories that have very exotic names (containing newlines).
