Tricky File Permission Question
I'm trying to answer the following question about file permissions in Unix. Consider a file with the following permissions:
rwx---r--
I am not the owner of this file, but I am a member of the group of this file.
My question is: do I have read access to this file?
I thought the answer was YES, since the world has read access to this file. But, a sysadmin is telling me that the answer is NO, since the group access bits are all off.
Can someone provide an authoritative answer?
I would try to answer this for myself, but at the moment, I don't have access to a Unix box with sufficient priveleges.
Thanks.

faxanswer
FAXANSWER(8) System Manager's Manual FAXANSWER(8)
NAME
faxanswer - tell a HylaFAX server to answer the telephone
SYNOPSIS
/usr/sbin/faxanswer [ -q queue-dir ] [ -h how ] modem
DESCRIPTION
faxanswer sends a message to the HylaFAX faxgetty(8) process servicing modem telling it to answer the telephone. This is useful, for exam-
ple, when a modem is used on a shared phone line and the server is configured to not normally answer the phone.
The specified modem can either be the name (typically the last component of the terminal port the modem is attached to), or the full name
of the associated FIFO named pipe file, e.g. ``FIFO.ttym2''.
OPTIONS
-q dir Use a spooling area other than /var/spool/hylafax.
-h Specify exactly how the phone should be answered. By default, the server process is instructed to answer the phone and accept
any kind of call (voice, data, fax). Discrimination of the type of call is dependent on a modem's adaptive-answer support. The
-h option can be used to force the server to answer the phone for particular type of call: one of fax, data, voice, any, extern
(to force faxgetty to invoke an external application to to handle the call), or dialX (where X is a dialstring to dial before
initiating a fax reception). If using dialX, the specified dialstring will likely need to end with a semicolon (``;'').
FILES
/var/spool/hylafax default spooling area
/var/spool/hylafax/FIFO fifo for contacting faxq
Consult hylafax-server(5) for a complete discussion of the structure and content of the spooling area.
