This is how it look like in pure bash

cat /usr/lib/cgi-bin/index.cgi

#!/bin/bash
echo Content-type: text/html
echo ""
## make POST and GET stings
## as bash variables available
if [ ! -z $CONTENT_LENGTH ] && [ "$CONTENT_LENGTH" -gt 0 ] && [ $CONTENT_TYPE != "multipart/form-data" ]; then
read -n $CONTENT_LENGTH POST_STRING <&0
eval `echo "${POST_STRING//;}"|tr '&' ';'`
fi
eval `echo "${QUERY_STRING//;}"|tr '&' ';'`

echo  "<!DOCTYPE html>"
echo  "<html>"
echo  "<head>"
echo  "</head>"

if [[ "$vote" = "a" ]];then
echo "you pressed A"
  sudo /usr/local/bin/run_a.sh
elif [[ "$vote" = "b" ]];then
echo "you pressed B"
  sudo /usr/local/bin/run_b.sh
fi

echo  "<body>"
echo  "<div id=\"content-container\">"
echo  "<div id=\"content-container-center\">"
echo  "<form id=\"choice\" name='form' method=\"POST\" action=\"/\">"
echo  "<button id=\"a\" type=\"submit\" name=\"vote\" class=\"a\" value=\"a\">A</button>"
echo  "<button id=\"b\" type=\"submit\" name=\"vote\" class=\"b\" value=\"b\">B</button>"
echo  "</form>"
echo  "<div id=\"tip\">"
echo  "</div>"
echo  "</div>"
echo  "</div>"
echo  "</div>"
echo  "</body>"
echo  "</html>"

PHP is likely the easiest   Just make a file script php that contains  lt  php shell exec  yourscript sh      gt  and send anybody who clicks the button to that destination  You can return the user to the original page with header    lt  php shell exec  yourscript sh    header  Location  http   www website com page success true      gt    Reference  http   php net manual en function shell-exec php

As stated by Luke you need to use a server side language  like php  This is a really simple php example    lt  php if    GET  run          This code will run if  run true is set    exec   path to name sh        gt    lt  -- This link will add  run true to your URL  myfilename php run true -- gt   lt a href   run true  gt Click Me  lt  a gt    Save this as myfilename php and place it on a machine with a web server with php installed  The same thing can be accomplished with asp  java  ruby  python

This is really just an expansion of BBB s answer which lead to to get my experiment working   This script will simply create a file  tmp testfile when you click on the button that says  Open Script    This requires 3 files    The actual HTML Website with a button  A php script which executes the script A Script   The File Tree   root test  var www html  tree testscript  testscript   -- index html  -- testexec php  -- test sh   1  The main WebPage   root test  var www html  cat testscript index html  lt form action   testscript testexec php  gt       lt input type  submit  value  Open Script  gt   lt  form gt    2  The PHP Page that runs the script and redirects back to the main page   root test  var www html  cat testscript testexec php  lt  php shell exec   var www html testscript test sh    header  Location  http   192 168 1 222 testscript index html success true      gt    3  The Script    root test  var www html  cat testscript test sh     bin bash  touch  tmp testfile
