Writing a CGI program
My first CGI program with C/C++, Perl, Python, Shell, Ruby
which gcc g++ gfortran sh bash perl ruby python
index.pl
#!/usr/bin/env perl
print "Content-type: text/html\n\n";
print "Hello, World."; chmod a+x index.pl
./index.plindex.py
#!/usr/bin/env python
print "Content-type: text/html\n\n";
print "Hello, World."; chmod a+x index.py
./index.pyindex.c
#include <stdio.h>
int main(int argc, char* argv[]) {
printf("Content-type: text/html\n\n");
printf("Hello, World.\n");
return 0;
}gcc index.c -o index.cgi
./index.cgiindex.sh
#!/usr/bash
echo "Content-type: text/html\n\n";
echo "Hello, World.";chmod a+x index.sh
./index.shindex.rb
#!/usr/bin/env ruby
# one way
# puts "Content-type: text/html\n\n"
# puts "<html><body>This is a test</body></html>"
# puts "Hello, World."
# another way
require 'cgi'
cgi = CGI.new
puts cgi.header
puts "<html><body>This is a test</body></html>"chmod a+x index.rb
./index.rb
