You have a mutant problem:

word:/tmp>uname -a 
FreeBSD word.smith.net.au 3.0-CURRENT FreeBSD 3.0-CURRENT #0: Wed Jan  7 07:57:45 CST 1998     root@word.smith.net.au:/local0/build/src/sys/compile/WORD  i386
word:/tmp>cp /bin/sh .
word:/tmp>echo echo hello world | ./sh
hello world
word:/tmp>rm ./sh
override r-xr-xr-x  mike/bin for ./sh? y
word:/tmp>ls -l ./sh
ls: ./sh: No such file or directory
