Re: Search and Replace

Hi,

Yes there are quite a few ways to do that, another example:

GLOBAL REPLACE in the files:
awk '{gsub("call", "mall", $0); print > FILENAME}' *.kumac
change call to mall in all *.kumac files

Word of CAUTION: If you process really big files you may run into trouble, 
that only part of your file will be processed.  Above procedure has a limit 
about 32K lines, rest of your file will be lost!  (that was my IRIX gawk 
experience) I think sed is better, but it may have limit too.  Better check.
