Multiple not statement in AWK
Hi

I have a logfile that do grow large rapid, so I like to create a new one with needed info.
For some reason the tail -d do not like to redirects its output to a file.
Code:
tail -f  /var/log/daemon.log | grep -vE '(snmpd|ntpd)'

gives me real time log of all lines without "snmpd" and "ntpd"
This is what I what.
Code:
tail -f  /var/log/daemon.log | grep -vE '(snmpd|ntpd)' >newlog

Do not work


Code:
tail -f  /var/log/daemon.log | grep -vE '(snmpd|ntpd)' | tee newlog

Do not work


So I found this working solution:
Code:
tail -f log | awk '{if ($1 == "Rough") print $5 | "tee mySecondFile.txt"}'

I did change some to:
Code:
  tail -f daemon.log | awk '{ if (!($0 ~ /snmpd/) || !($0 ~ /ntpd/)) print | "tee newlog"}'

This gives me the oposit of what I whant. All logs with "snmp" and "ntpd"


So I tried this
Code:
 tail -f daemon.log | awk '{ if (!($0 ~ /snmpd/) || !($0 ~ /ntpd/)) print | "tee newlog"}'

Seems to give me all line and does not remove the lines with "snmpd" and "ntpd"


Any idea of how to get this correct?

ntp-wait

ntp-wait(1)							   User Commands						       ntp-wait(1)

NAME

       ntp-wait - Wait for ntpd to stabilize the system clock

SYNOPSIS

       ntp-wait [-flags] [-flag [value]] [--option-name[[=| ]value]]

       All arguments must be options.

DESCRIPTION

       ntp-wait will send at most num-tries queries to ntpd(8), sleeping for secs-between-tries after each status return that says ntpd(8) has not
       yet produced a synchronized and stable system clock.

       ntp-wait will do this quietly, unless the -v flag is provided.  This can be useful at boot time, to delay the  boot  sequence  until  after
       ntpd -g has set the time.

OPTIONS

       -n number, --tries=number
	      Number of times to check ntpd.  This option takes an integer number as its argument.  The default number for this option is:
		   100

		      The maximum number of times we will check ntpd to see if
		      it has been able to synchronize and stabilize the system clock.

       -s secs-between-tries, --sleep=secs-between-tries
	      How  long  to  sleep  between  tries.  This option takes an integer number as its argument.  The default secs-between-tries for this
	      option is:
		   6

		      We will sleep for secs-between-tries after each query
		      of ntpd that returns "the time is not yet stable".

       -v, --verbose
	      Be verbose.

		      By default, ntp-wait is silent.
		      With this option, ntp-wait will provide status information.

       -?, --help
	      Display usage information and exit.

       -!, --more-help
	      Pass the extended usage information through a pager.

       -v [{v|c|n --version [{v|c|n}]}]
	      Output version of program and exit.  The default mode is `v', a simple version.  The `c' mode will print copyright  information  and
	      `n' will print the full copyright notice.

EXIT STATUS

       One of the following exit values will be returned:

       0  (EXIT_SUCCESS)
	      Successful program execution.

       1  (EXIT_FAILURE)
	      The operation failed or the command syntax was not valid.

       70  (EX_SOFTWARE)
	      libopts had an internal operational error.  Please report it to autogen-users@lists.sourceforge.net.  Thank you.
