UNIX for Dummies Questions & Answers

Hi All,

I've recently run a script that inserts the filename into all files of my active directory. Now I want to move the filename string and have it replace text a few lines down.

In other words, here's what I'm trying to do. Here is a file called 'goodtimes':

"
goodtimes
Hi, Welcome to the website.
blah blah blah
Cold beer creates headaches.
"

How can I move the word 'goodtimes' to the last line and have it replace the word 'headaches'? I.e.,

"
Hi, Welcome to the website.
blah blah blah
Cold beer creates goodtimes.
"

Thanks.

Code:

for file in all_files*
 do
  awk -v f="goodtimes" '$0~f{n=NR;sub(f,"");next}NR==n+line{sub("headaches",f)}1' line=3 "$file" > "$file".tmp && mv "$file".tmp "$file"
 done

Test it first without the mv statement.The code is based on the samples given here, modify if needed.
