This even does the grepping in parallel, so if syslogs is bigger than your disk cache this will go considerably faster than reading the file from disk over and over again. The option -j0 may be useful to you as well.

Hello,
I have multiple functions within a shell script. eg. function_database_backup, unix_tar_creation, etc.

syslog.auth
syslog.auth(4) Kernel Interfaces Manual syslog.auth(4)NAME
syslog.auth - authorization file for accepting remote syslog messages
SYNOPSIS
# format: Each fully qualified host name on a separate line hostname.domain_name
DESCRIPTION
The /etc/syslog.auth file specifies which remote hosts are allowed to forward syslog messages to the local host. For the sake of security,
only messages coming from remote hosts listed in the local /etc/syslog.auth file will be logged by the syslogd daemon.
If the /etc/syslog.auth file does not exist, then messages coming from any host will be accepted.
Each remote host name should appear in a separate line in /etc/syslog.auth. A line started with the # character is considered as a comment
and is thus ignored.
A host name must be a complete domain name such as trout.zk3.dec.com. If a domain host name is given, it must either appear in the local
/etc/hosts file or be able to be resolved by the local name server (BIND).
Note that a host name can have at most as many characters as defined by the MAXHOSTNAMELEN constant in <sys/param.h>, although each line
in the /etc/syslog.auth file can have up to 512 characters.
The /etc/syslog.auth file must be owned by root and has a permission of 0600.
To invoke a new version of the /etc/syslog.auth file, run the following command (as the super user) to initialize the syslogd daemon: kill
-HUP `cat /var/run/syslog.pid`
EXAMPLES
The following example provides a typical authorization file: # format: Each fully qualified host name on a separate line
c3poid.rvo.dec.com r2d2id.ckt.dec.com
FILES
Location of the authorization file.
