If your textfile is strict, as in your group will always be called "Group" followed by a space and a word and will not have any spaces in the group name, and similarly for the names after .html, this should work.
#!/bin/bash
parseNdostuff(){
case $1 in
Group)
shift
mkdir $1
cd $1
;;
*.html)
link=$1
shift
echo $link > $1
;;
*)
cd ..
;;
esac
}
while read line
do
parseNdostuff $line
done < mytext.txt
Just do a while read line and your text file input at the end < mytext.txt, and feed it to a function i wrote. The reason I chose to do it in a function was for simplicity of dealing with each line, plus being able to easily use case and shift.
Some details, if you're noob...:
$1 is the first argument of the function (the $ variables are special, look them up)
shift pushes down the arguments ($1 gets dropped, $2 becomes $1, $3 -> $2)
when it creates a directory it cd into that directory so when the statement runs again and sees the .html lines it makes the files and inputs the link all in the proper directory.
*) is all other cases, so if you have a blank line between groups, it will just cd .. and go down a directory, and you'll be back where you started your script. Note, all these cd's are relative to your script placement.
