Start mplayer in the framebuffer

It's made for a script use, where you have 3 parameters:

1. parameter is the filename

2. (optional) the encoding for subtitles

3. (optional) the scaling of the video, since fullscreen doesn't mean that the video will be scaled.

List OSX applications and versions.

Uses find, plutil and xpath.

Note: Some applications don't have proper information. system_profiler might be better to use.

It's a bit slow query.

Due to command length limit, I removed -name "*.app" and CFBundleName.

Compare a remote file with a local file

Or, if you have restricted access for sftp only, I think you can still do this:

diff /path/to/localfile <(scp [email protected]:/path/to/remotefile >(cat))

while series of video and subtitles have unmatched file names, rename subtitles the same as video files.

Subtitles' file names contain S04E01, S04E02, ... S04E12 and end with ".smi".

Videos' file names contain S04E01, S04E02, ... S04E12 and end with ".avi".

You can change the patterns by changing `ls *S04E$jj*.smi` and `ls *S04E$jj*.avi` parts.

You can change the number of starting and ending file by changing `seq -f "%02.0f" 1 12` part.
