Something like this:
Code:
#/bin/bash
clear
transaction=0
sales=0
total=0
MIN=0
MAX=0
while true
do
    echo -e "Enter sales price: \c"
    read sales
    $((sales)) || break # if sales = 0 then finish
    [ $sales -gt $MAX ] && MAX=$sales
    [ $transaction -eq 0 ] || [ $sales -lt $MIN ] && MIN=$sales
    $((transaction++))
    $((total+=sales))
done
echo "Number of Transactions : $transaction"
echo "Total Sales : $total"
echo "Max amount : $MAX"
echo "Min amount : $MIN"
echo "Average : $((total/transaction))"
[ $total -lt 100 ] && echo " Sorry, we do not take credit cards for sales less than $100."

nifind

NIFIND(1)						      General Commands Manual							 NIFIND(1)

NAME

       nifind - find a directory in the NetInfo hierarchy

SYNOPSIS

       nifind [ -anvp ] [ -t timeout ] directory [ domain ]

DESCRIPTION

       nifind  searches for the named directory in the NetInfo hierarchy.  It starts at the local domain and climbs up through the hierarchy until
       it reaches the root domain.  Any occurrences of directory are reported by directory ID number.  If the optional domain argument	is  given,
       then nifind stops climbing at that point in the hierarchy.  The domain argument must be specified by an absolute or relative domain name.

       When invoked with the -a option, nifind searches for the named directory in the entire NetInfo hierarchy (or the subtree with domain as the
       root if domain is specified).   The -n option exempts local domains from the search.

       nifind uses a default two second connection timeout when contacting a domain.  The connection timeout can be overridden with the -t option.

OPTIONS

       -a     Search for directory in the entire NetInfo hierarchy.

       -n     Exempt local directories from the search.

       -p     Print directory contents.

       -t timeout
	      Specify an integer value as the connection timeout (in seconds).

       -v     Produce verbose output.

EXAMPLES

       % nifind /printers/inky
       /printers/inky found in /software, id = 202
       /printers/inky found in /, id = 357

       % nifind  -a /machines/mailhost /sales
       /machines/mailhost found in /sales, id = 234

       % nifind -v /users/uid=164
       /users/uid=164 not found in /sales/polaris
       /users/uid=164 not found in /sales
       /users/uid=164 found in /, id = 451

       % nifind -p /machines/mailhost
       /machines/mailhost found in /sales, id=171
       name: zippy mailhost
       ip_address: 192.42.172.5

       /machines/mailhost found in /, id = 350
       name:  zorba mailhost
       ip_address: 192.42.172.1

BUGS

       nifind does not complain if domain is not an ancestor specified in a normal search.
