Hi,
I have to execute a Linux "more" command in php from a particular offset, format the result and display the result in Browser.
My Code for the above is :
<html>
<head>
<META HTTP-EQUIV=REFRESH CONTENT=10>
<META HTTP-EQUIV=PRAGMA CONTENT=NO-CACHE>
<title>Runtime Access log</title>
</head>
<body>
<?php
$moreCommand = "more +3693 /var/log/apache2/access_log | grep -v -e '.jpg' -e '.jpeg' -e '.css' -e '.js' -e '.bmp' -e '.ico'| wc -l";
exec($moreCommand, $accessDisplay);
echo "<br/>No of lines are : $accessDisplay[0] <br/>";
?>
The output at the browser is :: No of lines are : 3428 (This is wrong)
While executing the same command using command line gives a different output. My code snippet for the same is :
<?php
$moreCommand = "more +3693 /var/log/apache2/access_log | grep -v -e '.jpg' -e '.jpeg' -e '.css' -e '.js' -e '.bmp' -e '.ico'| wc -l";
exec($moreCommand, $accessDisplay);
echo "No of lines are : $accessDisplay[0] \n";
?
The output at the command line is :: No of lines are : 279 (This is correct)
While executing the same command directly in command line, gives me output as 279.
I am unable to understand why the output of the same command is wrong in the browser. Its actually giving the word count of lines, ignoring the offset parameter.
Please help !!
Thanks,
Amit
