Trying to search a log file for a string, starting from a certain point in the log file. I want to return the number of lines that contain the search string and the total number of lines in the log file. Here's the part of the script I'm having problems with:
The variables are set earlier in the script and are:
$lineslastrun=8
$searchpattern="test data"
The log file looks like this:
When I run the script with 'set -x' I get the following:
I would like awk to only return the data specified in the END statement but it is returning every line after 8. If it does that then 'echo $1' and 'echo $2' will return Total lines and Number of hits.
I can't seem to get awk to search for strings with spaces. The search pattern above should have returned '2' but it's returning '0'. If I search for a pattern without a space it works fine.
Hi!
Been working on a script and I've been having a problem. I've finally narrowed it down to this variable I'm setting:
servername=$(awk -v FS=\/ '{ print $7 } blah.txt | sed 's\/./-/g' | awk -v FS=\- '{print $1}')"
This will essentially pare down a line like this:

substr_count
SUBSTR_COUNT(3) 1 SUBSTR_COUNT(3)substr_count - Count the number of substring occurrencesSYNOPSIS
int substr_count (string $haystack, string $needle, [int $offset], [int $length])
DESCRIPTION substr_count(3) returns the number of times the $needle substring occurs in the $haystack string. Please note that $needle is case sensi-
tive.
Note
This function doesn't count overlapped substrings. See the example below!
PARAMETERS
o $haystack
- The string to search in
o $needle
- The substring to search for
o $offset
- The offset where to start counting
o $length
- The maximum length after the specified offset to search for the substring. It outputs a warning if the offset plus the length is
greater than the $haystack length.
RETURN VALUES
This function returns an integer.

EXAMPLES
Example #1
A substr_count(3) example
<?php
$text = 'This is a test';
echo strlen($text); // 14
echo substr_count($text, 'is'); // 2
// the string is reduced to 's is a test', so it prints 1
echo substr_count($text, 'is', 3);
// the text is reduced to 's i', so it prints 0
echo substr_count($text, 'is', 3, 3);
// generates a warning because 5+10 > 14
echo substr_count($text, 'is', 5, 10);
// prints only 1, because it doesn't count overlapped substrings
$text2 = 'gcdgcdgcd';
echo substr_count($text2, 'gcdgcd');
?>
