in thread Run sequential processes (Matlab, SAS, etc.) from Perl

You are correct on both counts. The matlab (or sas) process runs in the background and I am immediately given access to the command line.. I think fg and/or wait will do what I want. I'll give it a try. Thanks!

[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
