sed special characters issues
I am dusting off the sed cobwebs and had a basic question:

I have a file that contains:
Code:
$firewall = "on";
$cache = "on";
$dataset{'mary had a little lamb'} = "on";

and want to only change the contents of what is between the single quotes:
Code:
$dataset{'big bad wolf'} = "on";

I tried several combinations but to no evail:

Code:
sed 's/^\$dataset{'*'} = "on"\;/\$dataset{'big bad wolf'} = "on"\;/' test.txt
sed "s@^$dataset{'*'} = "on";@$dataset{'big bad wolf'} = "on";@" test.txt
sed 's@^*$@&'big bad wolf' test.txt

So essentially saying, whatever sed finds whats in between the single quotes replace it with "big bad wolf"

Someone please enlighten me!
