Full Discussion: KSH Script to watch log files for 2 strings
Top Forums Shell Programming and Scripting KSH Script to watch log files for 2 strings Post 302447307 by konsolebox on Sunday 22nd of August 2010 11:03:00 AM
Old 08-22-2010
I know some of ksh but I'm not yet used to it so I wrote this in bash. I hope you at least get the concept:
Code:
#!/bin/bash

LOGFILE=<path to logfile>

C0=$(fgrep -c 'Connection Error' "$LOGFILE")
F0=$(fgrep -c 'Failure in sending' "$LOGFILE")

function killProcs {
	...
}

while sleep 40s; do
	if
		C1=$(fgrep -c 'Connection Error' "$LOGFILE")
		(( C2 = C1 - C0, C0 = C1 ))
		[[ C2 -ge 30 ]]
	then
		killProcs
		# break?
	elif
		F1=$(fgrep -c 'Failure in sending' "$LOGFILE")
		(( F2 = F1 - F0, F0 = C1 ))
		[[ F2 -ge 30 ]]
	then
		killProcs
		# break?
	fi
done

gzegrep

GZGREP(1)						      General Commands Manual							 GZGREP(1)

NAME

       gzgrep, gzegrep, gzfgrep - search possibly compressed files for a regular expression

SYNOPSIS

       gzgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       gzgrep is used to invoke the grep on compress'ed or gzip'ed files. All options specified are passed directly to grep.  If no file is speci-
       fied, then the standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed	if  necessary  and
       fed to grep.

       If  gzgrep  is  invoked as gzegrep or gzfgrep then egrep or fgrep is used instead of grep.  If the GREP environment variable is set, gzgrep
       uses it as the grep program to be invoked. For example:

	   for sh:  GREP=fgrep	gzgrep string files
	   for csh: (setenv GREP fgrep; gzgrep string files)
