    <p>Simple straight forward attempt, with some issues:</p> <pre><code>#!/bin/bash echo "Enter some numbers separated by spaces" read numbers # Initialise min and max with first number in sequence for i in $numbers; do min=$i max=$i break done total=0 count=0 for i in $numbers; do total=$((total+i)) count=$((count+1)) if test $i -lt $min; then min=$i; fi if test $i -gt $max; then max=$i; fi done echo "Total: $total" echo "Avg: $((total/count))" echo "Min: $min" echo "Max: $max" </code></pre> <p>Also tested with /bin/sh, so you don't actually need bash, which is a much larger shell. Also note that this only works with integers, and average is truncated (not rounded).</p> <p>For floating point, you could use bc. But instead of dropping into a different interpreter multiple times, why not just write it in something a bit more suitable to the problem, such as python or perl, eg in python:</p> <pre><code>import sys from functools import partial sum = partial(reduce, lambda x, y: x+y) avg = lambda l: sum(l)/len(l) numbers = sys.stdin.readline() numbers = [float(x) for x in numbers.split()] print "Sum: " + str(sum(numbers)) print "Avg: " + str(avg(numbers)) print "Min: " + str(min(numbers)) print "Max: " + str(max(numbers)) </code></pre> <p>You could embed it in bash using a here document, see this question: <a href="https://stackoverflow.com/questions/2128949/how-to-pipe-a-here-document-through-a-command-and-capture-the-result-into-a-vari">How to pipe a here-document through a command and capture the result into a variable?</a> </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
