I watch a lot of dvds and I almost always like to open the IMDb page for the movie I'm watching to find out more about the actors, the director, filming locations, etc.

The following script will launch an IMDb search for any dvds that are inserted in my drives (/dev/sr0 and /dev/sr1). It depends upon the title of the movie showing up as the disk label for the removable media device it is in. Most dvds and blurays do this correctly but there is a significant fraction that do not. Still, this is so easy to use (I've got it connected to a button on my desktop) that I find it extremely convenient even though it sometimes fails. I even use it to see if I've still got a dvd or bluray inside one of the drives. YMMVG.

imdb-disc:
Code:
#!/usr/bin/perl

my $dir = "/dev/disk/by-label";
my @labels = glob("$dir/*");
for my $label (@labels) {
    -l $label or next;
    my $dest = readlink($label);
    $dest =~ m{/sr\d+$} or next;
    $label =~ s{.*/}{};
    $label =~ s/_/ /g;
    exec("imdb", $label);
    print "$label\n";
}

It relies on the following two helper scripts.

imdb:
Code:
#!/bin/bash
url="http://www.imdb.com/find?s=all&q="
args=$(url-encode "$@")
firefox "$url$args" &> /dev/null
disown &> /dev/null
exit 0


url-encode:
Code:
#!/usr/bin/perl
#
# URL encodes all input args, with a few tricks
#
# Usage inside a bash script (the quotes around $@ are required):
#   
#    args=$(url-encode "$@")
#
#    args=$(url-encode `xclip -o`)


for (@ARGV) {
    s/^\s+|\s+$//;              # remove leading/trailing whitespace (ws)
    m/\s/ and $_ = qq{"$_"};    # interior ws => quote the string

    # Escape wacky characters
    s{([^-.~\w\s'/i$!*()])}{sprintf("%%%02X", ord($1))}seg;

    # Convert whitespace to plus signs
    s/\s+/+/g;
}
# "Return" (via print) one big string
print join "+",  @ARGV;
