[SOLVED] BASH Question: Using a loop to download a series of files

roystonlodge · 02-02-2010, 01:17 PM

Never mind, I figured it out myself.

Firstly, the old version of BASH I'm using doesn't support

Code:

for i in {1..27}

So I had to use

Code:

for i in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

Secondly, it was simply

Code:

#!/bin/bash
for i in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27
do
  wget http://www.gutenberg.org/files/26290/mp3/26290-$i.mp3
done

Sorry 'bout the pointless thread. I couldn't find a way to delete the thread, since I'd solved my own problem.

Quote:

I want to download some audiobooks from Gutenberg.org.

Unfortunately, Gutenberg doesn't save their audiobooks as one mp3 file. The audiobook is broken up into a series of mp3 files.

I want to use wget and a BASH script to download an entire audiobook, but I don't know how to place the variable inside the URL.

Here's a pseudo-idea of what I'm trying to do (I know this is the incorrect syntax. I just want to give you the idea.):

Code:

#!/bin/bash
for i in {1..27}
do
  wget http://www.gutenberg.org/files/26290/mp3/26290-"$i".mp3
done

In other words, I want to set a loop that tells wget to download
http://www.gutenberg.org/files/26290/mp3/26290-1.mp3
http://www.gutenberg.org/files/26290/mp3/26290-2.mp3
http://www.gutenberg.org/files/26290/mp3/26290-3.mp3
http://www.gutenberg.org/files/26290/mp3/26290-4.mp3
etc, all the way to
http://www.gutenberg.org/files/26290/mp3/26290-27.mp3

Anybody have some advice for me on the correct syntax?

Hello roystonlodge,

you may as well use the "-r" option of wget to download all mp3-files recursively. Read the manpage of wget, there are some interesting informations. Be aware of the differences in how wget handles http and ftp.

Just for completeness you can also use:

Code:

for i in $(seq 1 27)

in case wget cannot do this.
