#  I create a history file for each shell opened
#    define variable and export (sh, ksh, posix) 
#
#  HISTRYFILE=/roots-home/history/$$shell-history; export HISTRYFILE
# 
# THEN,  this is the crude and inefficient way I sorted the history
# 	files into months within the history directory.  
# 
# ls -al | grep Mar > Mar-history
# cat Mar-history | awk '{print "mv " $9 " Mar" }' > mvMar
# vi mvMar
# sh mvMar
# 
#   (the other option is to cat all the history files into one large file,
#      then sort and use uniq -d, this will produce only the lines that are unique.
#     the problem with this is that you do not preserve the sequence of commands)
