this is a script to extract data from a logfile for a particular date and time but gives some err in line no. 11,12,13,14 i guess it has some problem with expr command and seq.
Remove the space after the = and use backslash in place of forward slash.
I would like to extract the following fields from the text file attached. I copied the contents from a pdf file and pasted them into the text file so I can use awk to extract them. The layout is as listed below.

Hello,
is it possible to debug a script that is already running "on-demand"?
Somehow a command like "set -x" but once you've executed the script. And another one to disable debugging?
Thank you (0 Replies)

mt_rand
MT_RAND(3) 1 MT_RAND(3)mt_rand - Generate a better random valueSYNOPSIS
int mt_rand (void )
DESCRIPTION
int mt_rand (int $min, int $max)
Many random number generators of older libcs have dubious or unknown characteristics and are slow. By default, PHP uses the libc random
number generator with the rand(3) function. The mt_rand(3) function is a drop-in replacement for this. It uses a random number generator
with known characteristics using the Mersenne Twister, which will produce random numbers four times faster than what the average libc
rand() provides.
If called without the optional $min, $max arguments mt_rand(3) returns a pseudo-random value between 0 and mt_getrandmax(3). If you want a
random number between 5 and 15 (inclusive), for example, use mt_rand(5, 15).
Caution
This function does not generate cryptographically secure values, and should not be used for cryptographic purposes. If you need a
cryptographically secure value, consider using random_int(3), random_bytes(3), or openssl_random_pseudo_bytes(3) instead.
PARAMETERS
o $min
- Optional lowest value to be returned (default: 0)
o $max
- Optional highest value to be returned (default: mt_getrandmax(3))
RETURN VALUES
A random integer value between $min (or 0) and $max (or mt_getrandmax(3), inclusive), or FALSE if $max is less than $min.

EXAMPLES
Example #1
mt_rand(3) example
<?php
echo mt_rand() . "
";
echo mt_rand() . "
";
echo mt_rand(5, 15);
?>
The above example will output something similar to:
1604716014
1478613278
6
NOTES
Caution
The distribution of mt_rand(3) return values is biased towards even numbers on 64-bit builds of PHP when $max is beyond 2^32. This
is because if $max is greater than the value returned by mt_getrandmax(3), the output of the random number generator must be scaled
up.
