Run the Perl one-liner on the *nix command prompt.
My file "f4" is equivalent to your "/etc/syslog.conf" in the testcase below -

Code:

$ 
$ cat f4
first line
/var/log in this line
third line
and this line also has /var/log
fifth line
sixth line
and /var/log embedded in here too
$ 
$ perl -nle 'print if /\/var\/log/' f4
/var/log in this line
and this line also has /var/log
and /var/log embedded in here too

snmptrapfmt

SNMPTRAPFMT(8)						      System Manager's Manual						    SNMPTRAPFMT(8)

NAME

       snmptrapfmt - Receive and log SNMP trap messages from a trap handler.

SYNOPSIS

       snmptrapfmt [-d num] [-D] [-f cfgfile]

DESCRIPTION

       Snmptrapfmt  receives  SNMP trap data through a local pipe. The trap data is written to this pipe by a SNMP trap handler which is called by
       snmptrapd (configuration is done in /etc/snmp/snmptrapd.conf) during the installation if this package.  Snmptrapfmt  formats  the  received
       trap  data  according to the specifications in the configuration file /etc/snmp/snmptrapfmt.conf (see this file for the syntax). The output
       of the snmptrapfmt application may be written to a log file or forwarded to the syslog daemon.

       The option -d 1 should be specified to enable tracing. Trace information is then written to the file /var/tmp/snmptrapfmt.trc.

       If the option -f cfgfile is given, the output of the daemon is configured via the mentioned configuration file. If this option is not spec-
       ified, a default output format is used.

       If the option -D is given, the the program will daemonize into the background.

       The syntax of the configuration file is explained in /etc/snmp/snmptrapfmt.conf !

FILES

       /etc/init.d/snmptrapfmt is the start/stop script.

       /etc/snmp/snmptrapfmt.conf is the configuration file.

       /var/run/snmptrapfmt.pid is the PID file.

       /etc/snmp/snmptrapd.conf is the configuration file of the snmptrapd daemon, which calls the trap handler snmptrapfmthdlr.

       /usr/sbin/snmptrapfmt is the executable of the application.

       /usr/sbin/snmptrapfmthdlr is the executable of the trap handler.

       /var/run/snmptrapfmt.p is the communication pipe between the trap handler snmptrapfmthdlr and the formatter snmptrapfmt.

       /var/tmp/snmptrapfmt.trc is the trace file if the option -d is specified.

       /var/log/snmptrapfmt.log is the log file as specified in the configuration file.
