Remove echo once you're happy with the results.
Filenames being unique is not enough; no file's name can be a trailing subset of another filename either. For example, if you have files angle.txt and triangle.txt somewhere under /app and there is a file named /update/angle.txt, the while loop will overwrite both files under /app with the contents of /update/angle.txt.

update-boinc-applinks

update-boinc-applinks(1)												  update-boinc-applinks(1)

NAME

       update-boinc-applinks - create/remove symbolic links for anonymous BOINC applications

SYNOPSIS

       update-boinc-applinks [options]

DESCRIPTION

       update-boinc-applinks  creates  (or  removes)  symbolic links for anonymous BOINC applications and their associated app_info.xml files in a
       given BOINC data directory.

       Note: update-boinc-applinks is an extension for Debian users and is only available in Debian's boinc-client package.

OPTIONS

       For a full summary of options, run update-boinc-applinks --help.

       -h, --help
	      Show help message and all options.

       --create
	      Create symbolic links and project directories.

       --remove
	      Remove symbolic links and empty project directories.

       --data-dir=DIR
	      Manage symbolic links in the given directory DIR. If this option is not present, DIR defaults to the current working directory.

       --project=PROJECT
	      Manage symbolic links only for the given project PROJECT.  Run update-boinc-applinks --list-projects to get a list of  projects  for
	      which  anonymous applications are available and therefore can be replaced with PROJECT. If this option is not present, update-boinc-
	      applinks will manage symbolic links for all available projects.

       --list-projects
	      Show a list of projects for which anonymous applications are available. Normally those applications are provided by packages  called
	      boinc-app-PROJECT (e.g. boinc-app-seti).
