Rather than making the log files world-writeable, you might be better
off making them group writeable, giving the world read-only access, and
if you set the SGID bit on the directory then they are to be sure to be
owned by the same group (see
http://www.library.yale.edu/~lso/workstation/docs/permissions/sgid.htm).
For instance, if your forking process runs as p1user and p2user and
p3user and they are all a member of a group called "loguser", then you
can do
#set the umask either in the perl script or in something like the
#.bashrc script for each user via
umask 664
#create the directory
mkdir logdir/
#make sure the directory is group writeable
chmod g+w logdir
#make the directory SGID
chmod g+s logdir
#make it owned by the loguser group
chown loguser logdir
#the directory will now look like this,
#note the 's' in the permissions
drwxrwsr-x 2 kgoess loguser 4096 Aug 27 08:47 logdir/
#create a test file
touch logdir/foo
#the new file is now group writeable by the loguser group
-rw-rw-r-- 1 kgoess loguser 0 Aug 27 08:50 foo
