Perl script to create a separte log file that includes required info.

P: 5
I want to create a separate log that includes an I (logIN) , userid, and date/timestamp from a detailed log. This type of data compresses very well so I can store years of it. I need script to create an separate log files that can saved on each server. Since I dont know much about perl scripting. Your help will be appreciated.

Thanx

And what have you tried to do this? Why not try to do it if you haven't and post your code here if you get stuck.

See if that helps at least get some data into the file. You can worry about formatting after you get this working.

Use code tags otherwise Jeff is going to give you a well deserved tongue lashing ;)

Post the sample of logs/data that is there in "filename".
Here you are merely splitting the files on a space.

Expand|Select|Wrap|Line Numbers
  1. $LOGFILE = "/opt/app/siteminder/log/newlog1.log";
  2. open(LOGFILE) or die("Could not open log file.");
  3. foreach $line (<LOGFILE>) {
  4.     $w = "(.+?)";
  5.     $line =~ m/^$w $w \[$w:$w $w\] " $w"/;
  6.  
  7.     $Event     = $1;
  8.     $servername  = $2;
  9.     $date = $3;
  10.     $time     = $4;
  11.     $gmt     = $5;
  12.     $uid      = $6;
  13. print ("\t","\n","\t", $Event, $date, $time, $uid);
  14.  
  15.     # do line-by-line processing.
  16. }
  17. close(LOGFILE);

Ok, then you can either initiate the same grep function using either backtics or the system() function, or, see if Perl's grep function will work for you.

What does the input file look like?

Maybe English is not your first language, but your English grammar and spellling is not good and is making it difficult to understand you. Try to use good spelling and grammar as much as you can.

OK, now earlier you posted this:

Expand|Select|Wrap|Line Numbers
  1. $Event = $1;
  2. $servername = $2;
  3. $date = $3;
  4. $time = $4;
  5. $gmt = $5;
  6. $uid = $6;
  7.  
Now show me from the line you posted what each of those should be from the line you posted:

Expand|Select|Wrap|Line Numbers
  1. $Event = AuthAccept
  2. $servername = bos54637
  3. $date = 01/Oct/2008
  4. $time = 22:46:15
  5. $gmt = -0500
  6. $uid = ????
