Hi folks,
I'm hoping someone here is interested in tracking down a bug in our
/bin/sh . Changing directory within a backtick (``) subshell in sh
taints the parent's working directory. The following sample code gives
the expected result for /bin/csh, but breaks for /bin/sh
cd /tmp
echo .`cd /`.
pwd
Any takers?
Ciao,
Sheldon.
PS: And no, this is not an invitation to chat about the default shell
for the base system. :-)
PPS: Shhhh!
