It happened to me that I got a season of a tv-show which had all files under the same folder like /home/blah/tv_show/season1/file{1,2,3,4,5,...}.avi

But I like to have them like this:

/home/blah/tv_show/season1/e{1,2,3,4,5,...}/file{1,2,3,4,5,...}.avi

So I can have both the srt and the avi on one folder without cluttering much. This command organizes everything assuming that the filename contains Exx where xx is the number of the episode.

You may need to set:

if your filenames have spaces.

exported files will get a .r23 extension (where 23 is the revision number)

change 20 by the number of sessions you want to know (20 it's fair enough)

when sometimes do a "w" or "who" command and see an orphan console session from time ago, you could kill with this command.

where ttyS0 its the console to kill.

change 24073 to your pid

Just find out the daemon with $ netstat -atulpe. Then type in his name and he gets the SIGTERM.

does the same, but shows network-prefix.

create an archive of files with access time older than 5 days, and remove original files.

Uses the pid to get the full path of the process. Useful when you do not which command got picked from the path

Works under bash on linux. just alter the '-e' option to its corresponding equivalence in your system to execute escape characters correctly.

Pitch-correct play speed with mplayer. You can also use [] and {} keys to change play speed on-the-fly.

rips the audio and video stream of a movie. The two streams are stored separately.

This assumes that there is a 10.2 sec delay between the video and the audio (delayed).

To extract the original video into a audio and video composites look at the command on extracting audio and video from a movie

Takes an mpeg video and coverts it to a youtube compatible flv file.

The -r 25 sets the frame rate for PAL, for NTSC use 29.97

-vn removes tha video content, the copy option tells ffmpeg to use the same codec for generating the output

The quality ranges between 0 to 9, with the smaller number indicates a higher quality file but bigger too.

Using mplayer to extract audio file from a CD

It can be hard to spot differences in reformatted files, because of all the diff noise created by word wrapped lines. This command removes all the noise and performs a word-by-word diff. To ignore empty lines, add -B to the diff command. Also, if this is something you do often, you might want to check out the wdiff(1) program.

This command will let you just type c-a b (which means press 'ctrl' then 'a' then 'b'), and screen will save your copy buffer to /tmp/screen-exchange, and then execute xsel to copy the contents of that file into the system's X clipboard.

1. Install Conrad Parker's xsel from http://www.vergenet.net/~conrad/software/xsel/

2. Add these lines to your .screenrc

# Add cool line to make copying to x clipboard possible.

# This binds C-a b to copy screen's copy buffer to the system clipboard.

bind b eval writebuf 'exec /bin/sh -c "xsel -i -b < /tmp/screen-exchange"' 'exec /bin/sh -c "killall xsel"'

3. Restart screen.

4. Test it by typing c-a [ to enter copy mode.

5. Select some text using vi movement keys (h, j, k, l, etc...) and starting your selection by hitting the space bar, moving with vi movement keys, and then ending your selection with the space bar.

6. Type C-a b, and screen will use xsel to copy your screen copy buffer to the system's X clipboard buffer.

7. Then you can paste the screen copy buffer into any X program.

Note: If you're using Mac OSX, you can use pbcopy instead of xsel.

Also Note: The second exec in the .screenrc file, which runs killall on xsel, is necessary, because even when you redirect a file to xsel, xsel waits for you to press ctrl-c to kill it, and have it stop waiting for more input. Since xsel forces screen to wait, and I don't want to press ctrl-c, I send the equivalent of ctrl-c with killall causing xsel to write /tmp/screen-exchange to the X clipboard, and then exit. It's a hack, but it works. If you know how to get this to work without a lame hack leave a comment explaining how.
