Pause for response from the log file
Hello,
I am writing a shell script to search an active log file. If an "error" or "aborted" found, echo an acknowledgment message and wait until the user presses ENTER key.
tail -f log.file |nawk '
{print $0}
$0 ~ /error/ {
print "Error found. Press ENTER to acknowledge."
getline i < "-"
}
$0 ~ /aborted/ {
print "Error found. Press ENTER to acknowledge."
getline i < "-"
}
'
Because this is an active log file, the messages keep coming to the log file all the time. The next incoming message, after error or aborted found, is read as response to the message.
I may have multiple Putty sessions running at same time. Only Putty session that displayed message can accept the response from user.
Thanks.
George

xslt_set_log
XSLT_SET_LOG(3) 1 XSLT_SET_LOG(3)
xslt_set_log - Set the log file to write log messages to
SYNOPSIS
void xslt_set_log (resource $xh, [mixed $log])
DESCRIPTION
This function allows you to set the file in which you want XSLT log messages to, XSLT log messages are different than error messages, in
that log messages are not actually error messages but rather messages related to the state of the XSLT processor. They are useful for
debugging XSLT, when something goes wrong.
By default logging is disabled, in order to enable logging you must first call xslt_set_log(3) with a boolean parameter which enables log-
ging, then if you want to set the log file to debug to, you must then pass it a string containing the filename.
PARAMETERS
o $
xh -The XSLT processor link identifier, created with xslt_create(3).
o $log
- This parameter is either a boolean value which toggles logging on and off, or a string containing the logfile in which log
errors too.
RETURN VALUES
No value is returned.
NOTES
Note
Please note that file:// is needed in front of the path when using Windows.
EXAMPLES
Example #1
Using the XSLT Logging features
<?php
$xh = xslt_create();
xslt_set_log($xh, true);
xslt_set_log($xh, getcwd() . '/myfile.log');
$result = xslt_process($xh, 'dog.xml', 'pets.xsl');
echo $result;
xslt_free($xh);
?>
