PCRE negative lookahead

I have read many tutorials and cannot get this to work. I need to use pcre (because that is what the library in the software we are using uses) and pcregrep everything except /home from the /etc/fstab

pcregrep '(?!/home)' /etc/fstab

It returns the entire fstab (This is on a RHEL5 machine). What am i doing wrong. Is there any better way to do this with a Perl compatible regular expression

Thanks,

Sean

Why not just use:

grep -v /home /etc/fstab

( or pcregrep -v /home /etc/fstab )

With negative lookahead try:

pcregrep '^(?!.*/home)' etc/fstab
