# Quick fix for HPUX grep to allow the "-h" option which prevents output of
# filenames (C) RIK 1992
# NOTE: I do not recommend the use of this script outside of postgres,
#	get GNU grep instead.

# Some vars

ACTION=0		# Invoke sed
PARAMS=""		# Para list - may have to take out the "-h"
NUMFILES=-1		# Number of files on command line
GREP=/bin/grep		# Where is grep?
SED=/bin/sed		# Where is sed?
EXPR=/bin/expr		# Where for art thou expr?

# Check parameter list and take out the "-h" if necessary

		-*)	PARAM="$PARAM $i" ;;
		*)	NUMFILES=`$EXPR $NUMFILES + 1`
