# Program Name: fileType.sh
#
# Purpose: checks type of the file and returns the type
#
# Authors: M. Tridici, CMCC (mauro.tridici@cmcc.it), N. Haustein, IBM (haustein@de.ibm.com)
#
# Invokation: filetype.sh filename
#
# Input: 
# - filename from the iRODS server. It is composed of /$ZONE/path/name whereby path is the directory level past to the mount point
# - Some configuration variables need to be adjusted 
#
# Processing: 
# - map the file name from iRODS to the file name relative to the local mount point (NFS mount in iRODS) and the remote file system (GPFS)
# - determine the type of the file using file
# - return file type
# - exit 0 (always)
#
# Output: 
# - file type
# - return code is 0
#
