Check if folder exist using case
Is it possible to use case when checking if a folder exist?

I need to check if these folder exist [5 folders to be exact]. All of them could be present but I still need to check. If a folder is present, something will be processed. Different folder do different stuff.

is this possible?'

Thanks

A case statement is for testing multiple values of one variable. I fail to see how that could be useful for this particular problem.

Perhaps you could give us some pseudo code for what you want your script to do when each of the 5 folders exists or does not exist.

maybe something like this...

Code:
location=/home/myhome/dir
 
case $stuff in
     $location/folder1)
        #do something here
        ;;
     $location/folder2)
       #do something here
       ;;
    $location/folder3)
       #do something here
       ;;
    $location/folder4)
       #do something here
       ;;
   $location/folder5)
       #do something here
       ;;
esac

I want to check the existence of each folder then do something if folder is present.

Is this possible? or should I just use 5 ifs? any suggestions?

Thanks

What is the range of the variable stuff?

Were you thinking:-
Code:
location=/home/myhome/dir

for stuff in *
do 
   if [ -d $stuff ]
   then
      case $stuff in
           $location/folder1)
              #do something here
              ;;
           $location/folder2)
             #do something here
             ;;
          $location/folder3)
             #do something here
             ;;
          $location/folder4)
             #do something here
             ;;
         $location/folder5)
             #do something here
             ;;
         *)
             #Do something for any other value that is a directory
             ;;
      esac
   else
      # Do something for an item that is not a directory
   fi
done



Have I missed the point?

Of course, this will not work with files/directories starting with a full-stop, e.g. .profile




I hope that this helps

I'm still not quite sure what you are trying to do - perhaps you could define a function to test something is in a given folder like this:

Code:
location=/home/myhome/dir

function stuff_in
{
   for f in "$1"/*
   do
      [ -f "$f" ]
      return
   done
}

if stuff_in "$location/folder1"
then
   echo "$location/folder1 is populated"
fi

if stuff_in "$location/folder2"
then
   echo "$location/folder2 is populated"
fi

if stuff_in "$location/folder3"
then
   echo "$location/folder3 is populated"
fi

Again ignoring files starting with . (like .profile)
