Tips
- Watch the spaces
if [ -d "$tmpInternal" ]; then
rm -r $tmpInternal >> $dateError.txt
elif [ -d "$tmpExternal" ]; then
rm -r $tmExternal >> $dateError.txt
fi
- The increment operator in bash
while [ $revTmpInternal -lt $revInternal ]; do
((revTmpInternal++))
done
- to check if a file exists:
if [ -f m.patch ]; then
rm *.patch
fi

files=$(ls /tmp/*.cache)
if [ $files ]
then
echo "Cache files exist: do something with them"
else
echo "No cache files..."
fi
