Re: [Cocoadialog-users] Bourne Shell Script Equivalent to Perl Script Sample for CocoaDialog Dropdown

[Thomas P. <tp...@gm...>]

Thanks Bill.  That worked a treat.  The final code that I used to accomplish
this portion of the coding is shown below (in case it is useful to anyone
else).  In the recursion, I execute a command using the transient variable
$INPUT each time.  Builds and runs fine together with Platypus.

Cheers,

Thomas

CD="CocoaDialog.app/Contents/MacOS/CocoaDialog"
rv=`$1/Contents/Resources/$CD fileselect \
--title "Select your Fireflly Input Files for Batch Job Submission" \
--text "Select your Fireflly Input Files for Batch Job Submission"
--select-multiple --no-newline`

 if [ -n "$rv" ]; then
       # determine number of items returned
       NO_ITEMS=`echo -n "$rv" | wc -l`
       NO_ITEMS=`expr $NO_ITEMS + 1`
       echo "The number of files selected is $NO_ITEMS"
       COUNT=0
       echo -n "$rv" | while [[ $COUNT -lt $NO_ITEMS ]]; do
           read FILE
           INPUT="$FILE"
           echo "Running input file $INPUT"
           COUNT=`expr $COUNT + 1`
       done
 else
    echo "No Input file selected.  Application aborted."
    sleep 6
    exit 1
 fi
