in reply to Net::OpenSSH::Parallel examples

No problem:

use Net::OpenSSH::Parallel; my $pssh = Net::OpenSSH::Parallel->new(); $pssh->add_host($_) for @hosts; $pssh->push('*', scp_put => '/local/file/path', '/remote/file/path') +; $pssh->push('*', command => 'gurummm', '/remote/file/path', '/tmp/output'); $pssh->push($special_host, command => 'prumprum', '/tmp/output'); $pssh->push('*', scp_get => '/tmp/output', 'logs/%HOST%/output'); $pssh->run;

[Cosmic37]: now I have tried another blunder - can anyone explain why I am such a dunderhead?
[Cosmic37]: if ( $line =~ /$mydt/ ) { print $line; }
[Cosmic37]: I try to match successive date times stored in variable $mydt
[Cosmic37]: I guess it is searching for the string "$mydt"
[Corion]: Indeed cool, erix ;)
[Cosmic37]: rather than the value of $mydt which is a date time strong such as 2016-01-01 12:30:56
[Corion]: Cosmic37: No, but maybe $mydt doesn't contain what you think it does, or it contains characters that are special in a regular expression? Try if( $line =~ /\Q$mydt\E/) { ... for a literal match
[Cosmic37]: I mean string grrr
[Corion]: Maybe add an else branch in which you print what the values of $line and $mydt are?
[Cosmic37]: ah thank you I will try
