Hitting a URL from the command line

July 11, 2007 9:13 AM

Alternatives to lynx, wget and get from the unix command line?

I have a scheduled job that needs to hit a localhost URL once a day. Our servers don't have lynx or wget or get installed. Are there any alternatives? I've tried using telnet and Expect, and it works but when run through our scheduling app (Tivoli Workload Scheduler) I get a message "No environment-specified terminal type." even when I specify the terminal type. So I was wondering if there are other techniques I could try.

Do you have a compiler installed? I would try to compile wget from source. It's bound to be useful in the future as well.

curl. Or perl. Or python. Probably Ruby, too.

That said... wget is usually pretty easy to build/install locally if you have a shell and a compiler (./configure --prefix=/home/you/local or something like that, make, make install), so I usually do.

$ man bash # and search for "socket"

Assuming Perl is installed, you can install HTTP::Client locally and do

perl -MHTTP::Client -e 'print HTTP::Client->new()->get("http://localhost/path")'

nicwolff, i'll call your HTTP::Client and raise you an LWP:
perl -MLWP::Simple -e 'get("http://www.metafilter.com/")'

'lwp-request' is the perl answer. Fabulously useful tool, that.

I use 'lwp-request -Sexd' for a variety of tests, and also because it's easy to remember.

Whoops, throw a -l/home/you/lib (or whatever) in there if you've installed HTTP::Client under your user dir.

Yeah, I'd normally use LWP since it's installed here, but if it's not it's a lot to install just to make a simple HTTP request...

Ah, also see if 'netcat' is installed. If it is, you can do something like this:

nc -v www.somewebsite.com 80

...and pass it "GET / HTTP/1.0\r\r"

PHP is also an option:

php -r "file('http://metafilter.com/');"

if it's a BSD, there's a chance you'll have fetch installed. Worth a quick check, unless you're just working with a seriously stripped down server.
