you'll need to download the page with 'wget' then parse it using 'egrep' and regular expressions or so, check the man pages of these two programs to learn about them.

I think the regex will look something like this, but don't quote me because i could be wrong

s/<a href="(.*)">(.*)</a>/

now $1 will be the linked page, and $2 the title of the link.

in the future, start a new thread with a new question, that way the forum becomes more searchable for other users.

In answer to the "download web page from the shell prompt/in a shell script, display links" question at the top; I think wget does this conveniently. If you're on a linux box you probably already have it; if not, it's free and small. Google for it.

Not sure of the question, but I think your asking how to use arguments with shell scripts ??

Each argument is given a number. So the first argument to the file is $1 the second $2 and so forth.

The script itself is $0. Which is handy to use in case the file name changes down the track.

Functions in shell scripts also use this same format, so its wise to assign the arguments to better variables at the start of the script. EG

var_one="$1"
var_two="$2"
