bash - Linux Script: How to check for any lines that starts with but not contain -

-

i'm @ following directory...

/var/log/homes

and script check lines starts 'error' , contains word 'notauthorized' , not contains '13024' or '31071'.

within /var/log/homes/, there 700 files, doesn't matter...

below have...

#!/bin/bash  host=`hostname` date=`date` monitor='error' pattern='error' pattern2='notauthorized' ignore=13024 ignore2=31071 logfile='/var/log/homes/*' mailto='test@linux.com'  if [ -e $logfile ]   if [ `grep -i "$pattern" "$pattern2" "$logfile" | grep -v $ignore $ignore  ]       echo "errors found in $monitor @ $date - see log $logfile on server $host full details" |mail -s "alert - $errors in logs, please review" $mailto   elif [ `grep -i "$pattern2" "$logfile" |wc -l` -lt 1 ]    fi else    echo "logfile $logfile doesn't exist on server $host @ $date,     bad, please investigate" |mail -s "alert - $monitor monitor has issue" $mailto fi

this should work:

grep "^error" $logfile | grep "notauthorized" | grep -v "13024" | grep -v "31071"
  • grep "^error": lines starting ith "error"
  • grep "notauthorized": lines containing "notauthorized"
  • grep -v "xxx": lines not containing "xxx"

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
