I have a bash and perl script in a file located on a linux server instance running on AWS. I am attempting to put a web application on that same server that would server as a GUI to run that script. (I.E. put a button on a web page that, when clicked, would run the script located on the same server but in the bin directory)
Thank you
Once you have a webserver setup in your language of choice, make a handler for your request of choice. Once that's done, Google exec <language>, where <language> is the language you're writing it in. Here are references for a few popular languages:
I'm not sure how your server is setup and there's a possibility that the apache user might not have correct permissions to run some commands but like most programming languages like php have a command for running external commands.
Checkout - http://php.net/manual/en/function.exec.php
Step 1: Install a HTTP server
Step 2: Configure the server to handle certain files in a certain directory as CGI scripts.
Step 3: Add a <form> to your page that POSTs to a CGI script. Include a submit button. This isn't really a web-appy thing, running scripts on servers is ancient. See the guestbooks and counter-images of 90s webpages.
The script itself would look something like (in Perl):
#!/usr/bin/perl
use CGI;
# the following line is *strongly* recommended
use strict; use warnings; use CGI::Carp qw(fatalsToBrowser);
my $cgi = CGI->new();
print $cgi->header();
exec "/usr/bin/script-I-want-to-run", "--switch", "value";
In Bash this might work:
#!/bin/sh
echo "Content-type: text/plain"
echo ""
/usr/bin/script-or-whatever --switch value
Perl's CGI module will even help you with getting $cgi->parameters and stuff and can be absolutely recommended. You will find a lot of (mostly bad) tutorials on Perl CGI scripting in the interwebs when you ask Google. Read them anyway.
