    Here is the program. It assumes that that the MS tookit tail has been installed on the computer.

    #! /usr/bin/perl my $cmdtorun = "tail -f D:/prjct/logger/2013-06-05.dlg |"; open(TL, $cmdtorun) || die "Failed: $!\n"; while ( <TL> ) { print "Got: $_\n"; }

[james28909]: it is not an absolute date like "27" or "31". sometimes it is like wednesday or friday
[james28909]: and i need to format those special instances into an absolute date instead of "yesterday"
[stevieb]: ask a question on SoPW, and include at least a half-dozen examples of the input, and at least one example of expected output
[davido]: Exactly: SoPW. This isn't going to be solved easily in the CB.
[james28909]: in need "yesterday" and so on, to be absolute like "1" or "31"
[stevieb]: ...and throw some of your existing code into the equation as well, just so readers know you've given a try at it ;)
[james28909]: ok
[stevieb]: davido thanks for the link ;) I was being the typical lazy
[davido]: date parsing is hard. The more examples you can provide of the input (within reason) and expected output, the better.
[stevieb]: agreed. That's why I said at least a half-dozen. If enough of the different formats are present, the date/time folk may not have to request more. If they do, then at least there was a decent base to start with
