Sorry - I think I should have given more details. Sed is a `stream editor' which is common on unix boxes, but which has also been ported to DOS/Windows and other platforms. I use a script very like this to zoom through the files generated by Jade, to reformat some of the elements (which need to be parsed by a further tool). I use it like for f in *.html; do sed 'blah....' $f >$f-fixed done (unix-speak again, but it just applies the same script to each of the .html files in a directory, sending the output to a new file). As was pointed out, everything you can do in sed you can do in Perl. Sed's nice because you can quite naturally get quite complicated programs into a single line of a script (you can do this with Perl as well, of course, but...). I use Perl when I want to do something complicated, or where I don't mind maintaining a separate script, but use sed where I want to do something reasonably simple as a component in another script. There's More Than One Way To Do It...! I found a sed FAQ at http://www.ptug.org/sed/sedfaq.html All the best, Norman --------------------------------------------------------------------------- Norman Gray http://www.astro.gla.ac.uk/users/norman/ Physics and Astronomy, University of Glasgow, UK norman@xxxxxxxxxxxxxxx DSSSList info and archive: http://www.mulberrytech.com/dsssl/dssslist
