QUERY_STRING with multiples appearances of the same string prefix
I have a shell script and it works pretty well to pull out the query_string contents of a single instance of router=

But if I have multiple router= strings, it only pulls out the last one.

Is there a way to pull out every router= and if there is a multple string, to egrep them together under $CISCO


Code:
http://routerlog.cgi?router=router1-fa6-0.amrltx&router=router1-fa6-0.aus2tx&router=router2-fa6-0.aus2tx&router=router1-fa6-0.bkfdca&month=02&day=24&shour=12&sminute=00&ehour=23&eminute=59&string=

Code:
#!/bin/sh
echo "Content-type: text/html\n"
echo ""
CISCO=`echo "$QUERY_STRING" | sed -n 's/^.*router=\([^&]*\).*$/\1/p'`
MONTH=`echo "$QUERY_STRING" | sed -n 's/^.*month=\([^&]*\).*$/\1/p'`
DAY=`echo "$QUERY_STRING" | sed -n 's/^.*day=\([^&]*\).*$/\1/p'`
PMONTH=`date +%m`
PDAY=`date +%d`
if [ $MONTH = $PMONTH ] && [ $DAY = $PDAY ] ; then 
SYSLOG="cat braslog"
else
SYSLOG="zcat braslog.$MONTH.$DAY.gz"
fi
SHOUR=`echo "$QUERY_STRING" | sed -n 's/^.*shour=\([^&]*\).*$/\1/p'`
SMINUTE=`echo "$QUERY_STRING" | sed -n 's/^.*sminute=\([^&]*\).*$/\1/p'`
EHOUR=`echo "$QUERY_STRING" | sed -n 's/^.*ehour=\([^&]*\).*$/\1/p'`
EMINUTE=`echo "$QUERY_STRING" | sed -n 's/^.*eminute=\([^&]*\).*$/\1/p'`
STIME="$SHOUR:$SMINUTE"
ETIME="$EHOUR:$EMINUTE"
STRING=`echo "$QUERY_STRING" | sed -n 's/^.*string=\([^&]*\).*$/\1/p' | \
sed -e "s/+/ /g" -e "s/%22/\"/g" -e "s/%2C/,/g" -e "s/%2F/\//g" -e "s/%3A/\:/g" -e "s/%26/\&/g" -e "s/%7C/|/g"`
echo "<html>"
echo "<body>"
if [ -z "$STRING" ] ; then
results=`$SYSLOG | egrep "$CISCO" | nawk '$3>=from&&$3<=to' from="$STIME" to="$ETIME" | nawk 'sub("$", "<br>")'`
else
results=`$SYSLOG | egrep "$," | egrep -i "$STRING" | awk '$3>=from&&$3<=to' from="$STIME" to="$ETIME" | nawk 'sub("$", "<br>")'`
fi
echo $results
echo "</body></html>"

I wanted to add the router= string will change on each submission. Sometimes just one router and other times there will be many. Each with a different router name.

I found a rather crude way of putting my multiple same prefix strings in a file. Any suggestions to clean this up?

Code:
echo "$QUERY_STRING" | nawk 'gsub(/&/,"\n")' | sed -n 's/^router=\([^&]*\).*$/\1/p' > query.txt

echo

echo(1B)					     SunOS/BSD Compatibility Package Commands						  echo(1B)

NAME

       echo - echo arguments to standard output

SYNOPSIS

       /usr/ucb/echo [-n] [argument]

DESCRIPTION

       echo writes its arguments, separated by BLANKs and terminated by a NEWLINE, to the standard output.

       echo  is useful for producing diagnostics in command files and for sending known data into a pipe, and for displaying the contents of envi-
       ronment variables.

       For example, you can use echo to determine how many subdirectories below the root directory (/) is your current directory, as follows:

	   o	  echo your current-working-directory's full pathname

	   o	  pipe the output through tr to translate the path's embedded slash-characters into space-characters

	   o	  pipe that output through wc -w for a count of the names in your path.

		    example% /usr/bin/echo "echo $PWD | tr '/' ' ' | wc -w"

       See tr(1) and wc(1) for their functionality.

       The shells csh(1), ksh(1), and sh(1), each have an echo built-in command, which, by default, will have precedence, and will be  invoked	if
       the  user  calls  echo without a full pathname. /usr/ucb/echo and csh's echo() have an -n option, but do not understand back-slashed escape
       characters. sh's echo(), ksh's echo(), and /usr/bin/echo, on the other hand, understand the  black-slashed  escape  characters,	and  ksh's
       echo() also understands a as the audible bell character; however, these commands do not have an -n option.

OPTIONS

       -n    Do not add the NEWLINE to the output.
