akfquery(1)                 General Commands Manual                akfquery(1)

NAME
       akfquery - use form data via CGI in shell scripts

SYNOPSIS
       akfquery field_name [alternative]

DESCRIPTION
       With  the  program  akfquery  you  can use forms with the GET-method in
       shell scripts.

       A field_name must be provided.  The program outputs the  decoded  field
       value  to  the standard output.  If the field doesn't exist or if it is
       empty, then it outputs the alternative, if given.  Otherwise the output
       is empty.

       If the field has multiple values, the program outputs  multiple  lines.
       This can happen for example with checkboxes.

       Special HTML-characters (<>&"') are converted to HTML-enities.

   Warning
       Shell  scripts  are suitable for quick temporary solutions or drafts in
       local, private networks.  But they shouldn't  be  used  for  productive
       work on the open Internet.

ENVIRONMENT
       QUERY_STRING
              contains the form data with the method GET

EXAMPLES
       # save in variable for reuse
       name=$(akfquery name "unknown")

       echo "<p>Hello $name.</p>"

       # for single use output you can directly include it
       # the line breaks don't really matter for HTML
       echo "<p>age:"
       akfquery age
       echo "</p>"

       # hobby is done with checkboxes
       echo "<ul>"
       for i in $(akfquery hobby "no hobbys")
       do
         echo "<li>$i</li>"
       done
       echo "</ul>"
