Thanks for the reply!

A separate utility would be fine with me, and probably easier to
maintain so I can understand where that comes from.
My main "problem" is that there is no such tool readily available so
I'll take the syscall variant in any form :)


Please note the name 'replace' is already taken (a tool from the mysql
toolbag, looks like a sort of simplified sed s/// pattern)
I'm also not sure it conveys the exchange/swap meaning, "replacing
a by/with b" means b is now where a was, but doesn't say anything about
where a went...
(I did say naming tool was the hardest part!)
