Hi,
I have to execute a Linux more command in PHP from a particular offset, format the result and display the result in the 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/>";
?>
</body>
</html>
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.
Thanks, Amit
