in reply to Can't print data from the input file in Command Line processing.

Also note that you could make your main loop much simpler using the <> operator.

#!/usr/bin/perl -w use strict; use Getopt::Std; my $prog = $0; $prog =~ s|.*/||; my %opts; getopts('o:', \%opts); my $cmd = $opts{o} || 1; my %wordDb = (); # Works exactly like your posted code is supposed to while(<>) { print "$ARGV ==> $_"; }

[Corion]: Meh. I have a very simple mechanism to scrape+track prices, and even to send me mail if something changes (via cron), but SQLite doesn't support window functions, so my simple SQL to determine a price change won't work :-( Maybe I should store the DB ...
[Corion]: ... in Pg, but that would mean that I'd have to deal with credentials and stuff :)
[Corion]: In fact, the whole thing is just four simple programs, one App::scrape, another being DBIx::RunSQL, and one some glue to convert a JSON object into an SQL INSERT statement (+DBI connect/execute), so it would be an incredibly simple solution...
[Corion]: ... but that simplicity falls down due to SQLite letting me down and me being too lazy to move to a real DB. Maybe DBD::CSV can handle window functions...
[hippo]: Pg has the "trust" mechanism if you don't fancy using credentials for a trivial db.
[Corion]: hippo: Oooh, that sounds quite nice - let me read the documentation on that :)
[hippo]: https://www. postgresql.org/ docs/current/ static/auth- methods.html#AUTH- TRUST
[erix]: or compile & run an instance as yourself (not user 'postgres')
