    use strict; use warnings; my $string1 = '"18/02/2018"'; print $string1 . "\n" if ($string1 =~ m/^"{1}[^"{1}]/); my $string2 = '"28/02/2018"'; print $string2 . "\n" if ($string2 =~ m/^"{1}[^"{1}]/); exit;
    The scalar string1 doesn't match...but why??

Opening bad Excel files

    I have an excel file which I need to extract data from. When I open it (with Spreadsheet::XLSX) it reports an empty file - no worksheets. This is not correct. Opening it with Excel itself shows that there is data.

    The problem might be that the file wasn't created by Excel itself - it may have been created by another program, which pretends to create 100% compatible Excel files.

    Is there any way to convert such files to valid Excel files, or is there another Perl module that can open and process them? I need a permanent solution, to process many such files automatically.

    The file can be found here:

    Thank you very much!

    Hi all,

    I am seeing the below error when trying to run an executable that I packed with PAR Packer (pp). How can I find out the original name of the shared object file I'm trying to get more clues as to why this error is coming up. Thanks.

    Hopefully a relatively simple one for somebody, but I've been staring at it too long it's all now a blur. I have the following output generated and it's either:


    ====================================================================== +======== LDP Sessions ====================================================================== +======== Peer LDP Id Adj Type State Msg Sent Msg Recv Up Tim +e ---------------------------------------------------------------------- +-------- ---------------------------------------------------------------------- +-------- No Matching Entries Found ====================================================================== +========


    Output 2

    ====================================================================== +======== LDP IPv4 Sessions ====================================================================== +======== Peer LDP Id Adj Type State Msg Sent Msg Recv Up Tim +e ---------------------------------------------------------------------- +-------- Targeted Established 822443 822431 273d 15:02:2 +0 ---------------------------------------------------------------------- +-------- No. of IPv4 Sessions: 1 ====================================================================== +========

    I'm trying to match using the following code to trigger an IF statement. Basically I'm looking for if the output contains an IP address then stop, otherwise keep going. But, it seems my IF statement returns true even if nothing that looks like an IP address is returned. I've been on regex101 to test my matching and it checks out there, but must be something obvious!

    if ( $output1 || $output2 =~ m/\d+\.\d+/gm ) { print "Found something"; exit; } else { print "Do this instead";

    Hi Monks, I am learning to write code to parse text files using grouped regular expressions. For the following section of code I am trying to find a way to determine if the entire group $1 is found in the input file. If it is I write group $2 to line. I am interested in modifying the code below to write MSISDN=notSet to $line if the entire line group $1 is not set in the code extract below? Thank your for your help

    pseudo code check line for tabMSISDN=digits; if found extract digits and assign to line otherwise assign MSISDN=notSet to the line for printing later

    Section of code

    if (/^(\t*MSISDN=(\d+));/) { print OUTFILE "Update Command $line\n" if defined $line; $line = "<$2>"; #group 2 #otherwise assign MSISDN=notSet to the line for printing later }

    full program below

    #!/usr/bin/perl use strict; use warnings; my $HSSIN='D:\testproject\sample-input.txt'; my $ofile = 'D:\testproject\sample-output.txt'; my $add; open (INFILE, $HSSIN) or die "Cant open input file"; open (OUTFILE,"> $ofile" ) or die "Cant open file"; my $line; while (<INFILE>) { if (/^(\t*MSISDN=(\d+));/) { print OUTFILE "Update Command $line\n" if defined $line; $line = "<$2>"; #group 2 } if (/(\t*ODBIC=([\w]+?\w.*));/) { #print OUTFILE "$line\n" if defined $line; #$line = $2; $add = $2; $line .= ",$add"; } if (/(\t*ODBOC=([\w]+?\w.*));/) { $add = $2; $line .= ",$add"; } } print OUTFILE "Update Command $line\n"; close INFILE; close OUTFILE;

    input file may contain multiple entries

    desired output Update Command <123476789678>,BIC,BAOC Update Command MSISDN=notSet,BIC, BAOC

    my $duration = 1000000; # in seconds my $wait = $duration; while ($wait >= 0) { $cmd1; $cmd2; $cmd3; $wait = $duration-time;#Decrement the time till it executed $cmd3 wi +th $duration }

    In the above code, i want to execute the while loop for $duration seconds. Once it reaches $duration while should break. Sleep won't help here , neither the time . Is there a way to acheive this

Counting PDL vectors in a PDL matrix

    Hi all, I am currently learning PDL and I've come up against a situation for which I cannot figure out how to proceed. I have a 2D array, comprised of multiple 1D byte vectors which may or may not be unique. I wish to count the number of unique vectors within the array - essentially a histogram of vector counts. My data is too big for here, but the following example demonstrates the issue I am having.

    pdl> p $x [ [0 1 2] [3 4 5] [6 7 8] [0 1 2] [0 1 2] [6 7 8] ]

    I know I can retrieve a list of unique elements:

    pdl> p uniq $x [0 1 2 3 4 5 6 7 8]

    I know I can retrieve a histogram of all elements:

    pdl> p scalar hist $x,0,256,1 [3 3 3 1 1 1 2 2 2 0 0 0 0 0 ....]

    What I would like is something like the following output:

    [0 1 2] 3 [3 4 5] 1 [6 7 8] 2
    I think my issue stems from the fact that PDL is designed for operations on PDL elements. I am currently contemplating if the best solution to my problem is to have a lookup table of the data I am putting in vectors to an index, for example:
    my %lookup = ( 0 => "0 1 2", 1 => "3 4 5", 2 => "6 7 8", ); # Then $x reduces down to $x = [ 0 1 2 0 0 2 ];

    Any advice would be welcome, as both PDL and numerical computing are new to me, thanks!

    Hi there,
    i need your help. I am trying to parse the following output.

    Configuration - DGCONF Protection Mode: MaxAvailability Databases: DB1 - Primary database DB2 - Physical standby database Properties: FastStartFailoverThreshold = '30' OperationTimeout = '30' FastStartFailoverLagLimit = '30' CommunicationTimeout = '180' ObserverReconnect = '0' FastStartFailoverAutoReinstate = 'TRUE' FastStartFailoverPmyShutdown = 'TRUE' BystandersFollowRoleChange = 'ALL' ObserverOverride = 'FALSE' ExternalDestination1 = '' ExternalDestination2 = '' PrimaryLostWriteAction = 'CONTINUE' Fast-Start Failover: DISABLED Configuration Status: SUCCESS
    As a result i need a hash like this
    $VAR2 = { 'Configuration' => 'DGCONF', 'ProtectionMode' => 'MaxAvailability', 'Databases' => { 'DB1' => 'Primarydatabase', 'DB2' => 'Physicalstandbydatabase' }, 'Properties' => { 'ExternalDestination2' => '', 'FastStartFailoverThreshold' => '30', 'ObserverReconnect' => '0', 'ObserverOverride' => 'FALSE', 'OperationTimeout' => '30', 'PrimaryLostWriteAction' => 'CONTINUE', 'FastStartFailoverAutoReinstate' => 'TRUE', 'BystandersFollowRoleChange' => 'ALL', 'FastStartFailoverPmyShutdown' => 'TRUE', 'ExternalDestination1' => '', 'FastStartFailoverLagLimit' => '30', 'CommunicationTimeout' => '180' }, 'ConfigurationStatus' => 'SUCCESS' };
    Please help!
