=head1 NAME
|
|
|
|
vid - Play videos matching strings in descending order of size
|
|
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<vid> [[grep options][string]]...
|
|
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
B<vid> recursively searches for videos and sort them by size. It then
|
|
filters out the names matching all the B<grep> expressions.
|
|
|
|
There can be multiple B<grep> expressions.
|
|
|
|
The searching is cached in B<.vidlist> in a parent dir or in the
|
|
current dir if no parents contain B<.vidlist>.
|
|
|
|
|
|
=head1 EXAMPLE
|
|
|
|
Play videos matching B<Documentary> but not B<BBC>:
|
|
|
|
vid Documentary -v BBC
