I have a process which I startup at boot time by adding the following line to my rc.local file
/usr/local/dcmtk/bin/dcmqrscp -c /home/db/dcmqrscp.cfg 2100 &
'dcmqrscp' is a server program, which receives files and writes them to a temp directory on disk. All Users can run a script which processes the files in this temp directory and deletes them after the processing is complete. The temp directory has 777 permission, but the files are created (by dcmqrscp) with a default permission of 644 and with the owner being root.
Should I start 'dcmqrscp' with a specific gid, to which all my users belong, so that they can delete the files in the temp directory, once they are done with their processing? What I'm looking for, is a way to make all the files created by 'dcmqrscp' program, world writeable, so that the script run by my users, will delete these files, once the processing is complete.
