wget - good way to grab a "list" of files?

Hi,

I'm trying to do something for one of my sites, which "grabs" a large number of images (in the region of around 100,000). ATM, it does something like;

Code:
while (<>) { 
  `wget -OID.gif 'http://www.domain.com/somewhere/image1234.gif'`; 
}

Basically, I'm wondering if there is a better way to grab them (all at once) .. i.e a delimited list, or even a .sh file;

Quote:

wget -OID.gif 'http://www.domain.com/somewhere/image12347.gif'
wget -OID1.gif 'http://www.domain.com/somewhere/image12345.gif'
wget -OID2.gif 'http://www.domain.com/somewhere/image12344.gif'
wget -OID3.gif 'http://www.domain.com/somewhere/image12343.gif'
wget -OID4.gif 'http://www.domain.com/somewhere/image12342.gif'
wget -OID5.gif 'http://www.domain.com/somewhere/image12341.gif'
...etc

Currently, the wget method is taking too long .. especially with the number of images I'm trying to grab.

TIA

the tick operator spawns your script.

why not using perl solution, which doesn't start another process?

For example, LWP module

Hi,

Yeah I tried using LWP::Simple::get(), but its almost as slow as wget :/

Surely there must be something where you can enter a list of URLs in a text file, and then have something go through and grab them Crazy

Do you have a solution yet? If not, did you ever consider 'man 1 wget'?

Specifically
wget -i some/file

where 'some/file' contains a list of URLs.

Hi,

That worked a charm - thanks Cool

I needed to grab 600,000 images, to running 600k seperate queries was impraticle (not that this way makes it much better, but still <G>).

I'm seperating them into;

/images/a
/images/b
/images/c
/images/d
/images/e
..etc

..based on the first character of the image name :)

Thanks again.

Cheers
