Portable anything is difficult, the question is how difficult.

If you give me the option of porting a shell script and a Perl script to a win32 environment, I'll take Perl. It's still not a fun job, but at least it isn't a painful job.

[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
[Cosmic37]: you are right $mydt did not contain what I expected... :-D I will now think :-D
[Cosmic37]: crunch...grind... whirr...gnashing metal crunching cogs...
