Like in elixir sinari's example, the -i switch is for "ignore case".

i was looking for something more complex. the "-i" will be slower when grepping through large files, which is what i'm dealing with.

i was thinking something along the lines of:

Code:
egrep "([pP]anic|[Ee]rror|[Ff]ail)" /var/log/messages

in this example, i know which letters may be small/upper case. so i took that into consideration. there are cases when u wont know, and i wanted to find a way to account for that, without using the "-i".

syslog.conf(4)						     Kernel Interfaces Manual						    syslog.conf(4)

NAME
syslog.conf - syslogd configuration file SYNOPSIS
facility.severity destination Where: Is part of the system generating the message, specified in /usr/include/sys/syslog_pri.h. See also the syslogd(8) reference page. The severity level, which can be emerg, alert, crit, err, warning, notice, info, or debug. See /usr/include/sys/syslog_pri.h. The syslogd daemon logs all messages of the specified severity level plus all messages of greater severity. For example, if you specify level err, all messages of levels err, crit, alert, and emerg or panic are logged. A local file pathname to a log file, a host name for remote logging or a list of users. In the latter case the users will receive messages when they are logged in. An asterisk (*) causes a message to be sent to all users who are currently logged in. DESCRIPTION
The /etc/syslog.conf file is a system file that enables you to configure or filter events that are to be logged by syslogd. You can specify more than one facility and its severity level by separating them with semicolons. You can specify more than one facility logs to the same file by separating the facilities with commas, as shown in the EXAMPLES section. The syslogd daemon ignores blank lines and lines that begin with an octothorpe (#). You can specify # as the first character in a line to include comments in the file or to disable an entry. The facility and severity level are separated from the destination by one or more tab characters. If you want the syslogd daemon to use a configuration file other than the default, you must specify the file name with the following com- mand: # syslogd -f config_file Daily Log Files You can specify in the /etc/syslog.conf file that the syslogd daemon create daily log files. To create daily log files, use the following syntax to specify the path name of the message destination: /var/adm/syslog.dated/ { file} The file variable specifies the name of the log file, for example, mail.log or kern.log. If you specify a /var/adm/syslog.dated/file path name destination, each day the syslogd daemon creates a sub-directory under the /var/adm/syslog.dated directory and a log file in the sub-directory, using the following syntax: /var/adm/syslog.dated/ date / file Where: The date variable specifies the day, month, and time that the log file was created. The file variable specifies the name of the log file you previously specified in the /etc/syslog.conf file. The syslogd daemon automatically cre- ates a new date directory every 24 hours and also when you boot the system. The current directory is a link to the latest date directory. To get the latest logs, you only need to reference the /var/adm/syslog.dated/current directory. EXAMPLES
The following is a sample /etc/syslog.conf file: # # syslogd config file # # facilities: kern user mail daemon auth syslog lpr binary # priorities: emerg alert crit err warning notice info debug # kern.debug /var/adm/syslog.dated/kern.log user.debug /var/adm/sys- log.dated/user.log daemon.debug /var/adm/syslog.dated/daemon.log auth.crit;syslog.debug /var/adm/syslog.dated/syslog.log mail,lpr.debug /var/adm/syslog.dated/misc.log msgbuf.err /var/adm/crash.dated/msgbuf.savecore kern.debug /var/adm/messages kern.debug /dev/console *.emerg * FILES
/etc/syslog.conf /etc/syslog.auth - Authorization file for remote logging. /usr/include/sys/syslog_pri.h - Common components of a syslog event log record. RELATED INFORMATION
Commands: /usr/sbin/syslogd(8), /usr/sbin/binlogd(8) System Administration delim off syslog.conf(4)
