How do I write a Perl script to use curl to process a URL?
I have a very simple task. I have a crontab that will run a script every hour. The script is meant to simply process a URL.
This is what I have. It doesn't work. I get a syntax error.
#!/usr/bin/perl
curl http://domain.com/page.html;
I haven't worked in Perl in years and wasn't very adept when I did.

Thanks, Alex for pointing me to the correct path!
crontab
*/30 * * * * curl http://domain.com/path.html
You can either use curl
via backticks
my $curl=`curl http://whatever`
or you can use WWW::Curl
.
To call any shell command from Perl, you can use system
:
system "curl http://domain.com/page.html";
Just enclose the shell command in quotes.
If shying away from executing command line tools from with Perl, the library equivalent is
use WWW::Curl::Simple;
my $curl = WWW::Curl::Simple->new();
my $res = $curl->get("https://stackoverflow.com");
The content you then access as in
print $res->content;
You may want to read up on https://metacpan.org/pod/WWW::Curl::Simple and the get method returns a https://metacpan.org/pod/HTTP::Response.
Try this if you need to pass multiple parameters.
my $cc = 'curl -v -X GET https://base-template.squarespace.com/blog/\?field1=value1\&format=json-pretty\&field3=value3';
print `$cc`;
