by Rahul Gupta (Sexton) on Jul 26, 2012 at 10:03 UTC
    I have tried this regular expression $_ =~ m/^REMOTE\s+\[(.*?)\]\s+(\S+)\s+(\S+)\s+(\S+)\s+(\S+)\s+\[(.*?)\]\s+(.*?)sec\s+(.*)MBytes\s+(.*)Mbits\/sec
    . it gives data from both strings.But <cd> String1:"REMOTE Mon Jul 16 21:49:33 2012 @@ ueh1 TNT 20490 1916 0.0- 1.0 sec 0.33 MBytes 2.74 Mbits/sec 6.056 ms 0/ 233 (0%)"; </c>having two values in last 6.056 ms and 0/ 233(0%) i have to make them optional. Please help me in this problem Thanx
        I have one array with 2 Strings:
        String1: "REMOTE [Mon Jul 16 21:49:33 2012] @@ [ueh1] [TNT] [2049 +0] [1916] 0.0- 1.0 sec 0.33 MBytes 2.74 Mbits/sec 6.056 ms 0/ + 233 (0%)". String2: "REMOTE [Mon Jul 16 21:49:34 2012] @@ [pdn1] [SSH] [2049 +9] [3] 1.0- 2.0 sec 0.34 MBytes 2.86 Mbits/sec".
        In "String1" I have two extra values that is "6.056 ms" and "0/ 233 (0%)" rest are same in both string; I tried this regex: m/^REMOTE\s+\[(.*?)\]\s+(\S+)\s+(\S+)\s+(\S+)\s+(\S+)\s+\[(.*?)\]\s+(.*?)sec\s+(.*)MBytes\s+(.*)Mbits\/sec
        but need to add the above mentioned two values of String1 in regex and make them optional so that both condition gets passed and last values stored in $10, $11.
        Can anyone help me?
        Thanks in advance
