Differences between 'su' version give different results in the following
shell script:
# !/bin/sh
func() {
su user > /dev/null 2>&1 << EOF
echo >> /tmp/b
EOF
}
if func; then
echo "access"
else
echo "no access"
fi
over fedora 17 I run - coreutils 8.15-8: if the file is not accessible
by user the script prints no access, and the other way around.
over rhel 6.3 we run - coreutils 8.4: the result of func is always
"access" without any dependency of the file permissions.. My first guess
was that it returns 0 because the 'su' command was succeeded, but with
strace you see that the script runs differently.
Is it a bug?
Thanks.
