syslog grep/awk/sed display
What i am trying to do is pull all the "fail" and "error" from the HP-UX syslog except if it includes "sshd" or "ftpd" and IF the next line says "above message repeats NN time" display the next line.


Got some of it working with someones help with sed but Im more familiare with awk.

Trying to do this with awk:

Code:
cat syslog.log | sed -e '/sshd/d' -e '/ftpd/d' -e '/error/b' -e '/fail/b' -e d

I can do half:

Code:
awk '/(error|fail)/ { print; }' syslog.log

I want to add the !/(sshd|ftpd)/ to the awk statement in one statement, if possible.

Then I want to display the next line IF next line contains " above message repeats NN times"

I know how to display next next line:
Code:
awk '/(error|fail)/ { print; getline; print; }' syslog.log

But not sure how to do it ONLY if it contains " above message repeats NN times" and include the !/(sshd|ftpd)/

I know I can do it with multiple greps but I would like an awk one liner.

syslog

SYSLOG(8)                                                         System Logging                                                         SYSLOG(8)

NAME

       syslog-ng, syslogd

DESCRIPTION

       There are different syslog daemon implementations supported as the system's syslog service, currently syslogd, syslog-ng and rsyslogd

       The  first  installed daemon activates itself for the syslog service. Starting with openSUSE-11.2, it is rsyslogd, before it was syslog-ng.
       But this depends on the software selection during the installation.

       The name of the daemon used as syslog service is specified in the
       SYSLOG_DAEMON variable in /etc/sysconfig/syslog.

       The yast2 sysconfig module provides a comfortable way to switch to another installed daemon and restart the service.

       The /etc/init.d/syslog init script is able to handle all supported daemons.
