Ahem, ...
As much as i appreciate your appreciation i have a feeling that the reasoning behind your script is somewhat flawed: When you first run the loop the sed-statement will change all occurrences of "target" to whatever the grep gave as first hit. When the loop is executed for the second (or any subsequent) time it would try to change "target" to whatever grep provided as secod hit, but there will be no more instances of "target", because they all have been changed in the first run, yes?
This will only work if any subsequent expression will hit a subset of the previous one, which has just got changed. In this case i suppose there would be more efficient (and more elegant) ways to achieve the same result. How about you state your complete problem here and we have a review?
I hope this helps.
