Find Words - match

The match command uses Korn shell pattern-matching characters to find words in a dictionary. It can be used to help with crossword puzzles, or test your patterns.

					# Check usage
					if (($# < 1 || $# > 2))
					then
					print "Usage: $0 pattern [file]"
					exit 1

					# Check/set DICT to word dictionary
					: ${DICT:=${2:-/usr/dict/words}}
					# Open $DICT for input
					exec 0<$DICT
					# Read each word into WORD
					while read WORD
					do
					# This command didn't work on all systems. If
					# it doesn't on yours, use this instead of
					# exec 0<$DICT:
					#     cat $DICT | while read WORD
					#
					# If WORD matches the given pattern,
					# print the match
					[[ $WORD = $1 ]] && print - $WORD
