Welcome to the forum.
Your request is not quite clear. Please exercise due care when phrasing your specification. Do you want to replace tu8tu5 with the string constant $blckntifypass or the respective variable's contents? Are the single quotes around it required in your result, or are they to enable shell expansion of the variable? Is that the only line in the file or has it to be selected, are there more occurrences of tu8tu5?
