# Script     : pathscr
# Version    : 1.0
# Author     : Roland Rashleigh-Berry
# Date       : 13-Jan-2004
# Purpose    : List all files with no file extension defined to the PATH system
#              environment variable.
# SubScripts : none
# Notes      : The number of the directory in the path list is shown. Output is
#              sorted into script and directory number order which will be the 
#              order in which the script/command is searched for when invoked.
#
#              The files listed might not be scripts. They might be binaries or
#              command files as well as scripts. Also, in some rare cases, a 
#              script will have a file extension, but these will not be shown.
#
# Usage      : pathscr

# Within the $( ), change the path colons to spaces. You will
# then be left with a list of directories. For true directories,  
# list out the files and drop those with a period in the name.
# Format the output, sort and display.
