Shell Programming and Scripting

I want to make a script to use wget to find and download mp3s on a website into a directory with a name derived from that URL. So far I have:

#!/bin/sh
echo “MP3 Downloader”
echo -n "Enter full URL address of website or website subdirectory > "
read text

cd ~
mkdir $text
cd $text

wget -r -nc -k -np -U Mozilla/5.0 -A.mp3,oog -e robots=off -w 3 -l 7 --limit-rate=50k --random-wait --restrict-file-names=windows $text

My problem is the middle bit. I want to make a new directory based on the URL and then change to it before Wgetting.

I cannot input a URL (presumably because of the "/"s and I don't know how to resolve that.

Also $text seems to be good for one go only so I can't use it for any more instances.

Any help would be gratefully appreciated.

Depends on the url and what naming logic you want to create the directory.

What do you mean by "$text seems to be good for one go only so I can't use it for any more instances"? Everytime you run the script $text will have the value supplied via read command.

wget's "-x" option will make it create a hierarchy of directories when files are downloaded, i.e. it will create, in the current directory, www.somewebsite.com/path/to/file.mp3 . This is usually used with wget's recursive options but doesn't have to be. You can make it put the root in some other path with -P /path/to/somewhere

Thanks for the replies.

Corona, I think -X will be perfectly sufficient for my needs. Thanks.

Rik, I might be wrong but it seemed to me when I tried to use $text twice it only worked the first time. Ie in:-

#!/bin/sh
echo “MP3 Downloader”
echo -n "Enter new directory name> "
read text

cd ~
mkdir $text
cd $text

I 'm pretty sure the cd $text part doesn't work and the directory doesn't change to the newly created directory.

Anyway, that could all be moot, because, if I use -X I can hopefully simplify the code to:-

#!/bin/sh
echo “MP3 Downloader”
echo -n "Enter full URL address of website or website subdirectory > "
read text

wget -r -nc -k -np -X -U Mozilla/5.0 -A.mp3,oog -e robots=off -w 3 -l 7 --limit-rate=50k --random-wait --restrict-file-names=windows $text
