Passing a variable into a URL in Perl...

[jmg498]

It's been a while since I've programmed in Perl. I am having difficulty getting $station to go into the URL as shown below. Where am I going wrong? Thanks much!

---snippet---

print 'Enter the station ID: ';
chomp ($station = <STDIN>);

system ('wget "ftp://tgftp.nws.noaa.gov/SL.us008001/DF.of/DC.radar/DS.p19r0/SI.$station/sn.last"');

because you are using single-quotes, there is no interpolation.

simply concatenate...

system ('wget "ftp://tgftp.nws.noaa.gov/SL.us008001/DF.of/DC.radar/DS.p19r0/SI.'.$station.'/sn.last"');

On general principals I would recommend qq for strings which need interpolation:

system qq{wget "ftp://tgftp.nws.noaa.gov/SL.us008001/DF.of/DC.radar/DS.p19r0/SI.$station/sn.last"};
