# linuxGetFileAttrInfo.pl
#
# by Dean Giles 
# Version 1.0 
# January 4, 2007
#
# This Perl script lists standard information about a specified file including set attributes. 
# If the attribute it set it is listed.  The attributes can include: readOnly, hidden, system, subdirectory, 
# archive, shareable, noSuballoc (no Suballocation), transaction, notVirtual, immediatePurge, renameInhibit, 
# deleteInhibit, copyInhibit, adminLink, link, remoteDataAccess, remoteDataInhibit, compressImmediate, dataStreamCompress,
# doNotCompress, noStreamCompress, attrArchive (metadata archive bit), or volitile.

# This script has been designed to be run on Linux. 
# The API set can be downloaded from  http://developer.novell.com/wiki/index.php/Virtual_File_Services_for_NetWare. 
# 
# The Perl script requires the name of an NSS pool as input.  It requires that NSS be installed and an NSS pool be present.
