> ifs=' > ' for (old in `{9 ls *.$EXT}) { i think ls and the temporary file are getting in the way. if you use globbing and execing directly from the shell you can avoid quoting problems. for example,
for(old in *^' '^*.$EXT) ifs=$nl mv $old `{echo $old | sed 's/ //g'} and now for a digression .... this looks like c programming to me. unfortunately mv doesn't take pairs, so we can't get rid of the for loop, but we can generate parallel lists. i'm going to assume that ☺ isn't in any of your file names. you could pick something else. the trick here is to paste ☺ onto the end of every list element. that way we know that '☺ ' are end-of-token markers, and other spaces are just spaces. then we can delete the spaces without ☺s, then delete the ☺s and then turn the remaining spaces (they mark the end of a token) into newlines. i'm going to assume that $ext also contains the '.'. old = *^' '^*$ext ifs=$nl new = `{echo $old^☺ | sed 's/([^☺]) /\1/g s/☺//g s/ /\n/g' } (the last two sed steps are combinable; s/☺ /\n/g.) now that we have this, we can while(! ~ $#new 0){ mv $old(1) $new(1) old=$old(2-) new=$new(2-) } this reminds me, the whole ifs thing is awkward because it applies for the whole command which is almost never what you want. i modified rc to allow one to specify a backquote splitter. e.g. new = `$nl {echo $old^☺ | sed 's/([^☺]) /\1/g s/☺//g s/ /\n/g' } - erik
