Thanks for the reply. I should have added the complete text file but there are other variables in the file and I want to just look for only this occurrence of:

so:

Code:
$firewall = "on";
$cache = "on";
$dataset{'mary had a little lamb'} = "on";

Would this apply?

[code]
Code:
sed "/dataset/ s/'[^']*'/'new text'/" infile

this works but I need some clarification of the context of it.
