Top Forums Shell Programming and Scripting sed - Search and replace within pattern Post 302951777 by wbport on Monday 10th of August 2015 04:45:30 PM

This code, inspired by the O'Reilly book "sed & awk" might help:
Code:

 # Transform quoted text to uppercase.
 /".*"/{
 h
 s/.*"\(.*\)".*/\1/
 y/abcdefghijklmnopqrstuvwxyz/ABCDEFGHIJKLMNOPQRSTUVWXYZ/
 G
 s/\(.*\)\n\(.*\)".*"\(.*\)/\2"\1"\3/
 }
 

By the time the code reaches the "y" command there is nothing in the pattern space other than quoted text. Replace the "y" line with your own "s" command. The last two lines recreate the whole line except for the quoted part you changed is inserted.

HTH

P.S. You might want an "s" command (instead of the "y") like
Code:
s/[^A-Z]/?/g

to replace all non (uppercase) alphabetic characters with ? or just omit the "?" to replace with nothing.
