thanks i just tried it myself.

i have always used "find transactions -type f -newer start -not -newer
end | xargs -i grep operation:reload {}" on my glibc box and
eventually i thought xargs behaves the same way when i use busybox
grep on my uclibc box without the "-i i" and "{}".

sorry about that.
