Correct the asterisks can be any hex digit, The Blue must be exact. The red thats hard to say they also never change.

The Matching bits need to be at the beginning of the files.

Ah Yes there are several hundred occurrences and each needs to be in a separate file.
As for filename I would like it to include the original filename. Wait no the filename can be anything it don't even have to be in order thats a different project. LOL Sorry

Okay after the files are split I would use
Code:
for i in *; do mv "$i" "$( xxd -ps -l 55 "$i")"$i; done

to add the start hex code to the filename and then "better finder rename" to remove the parts of the hex that are unnecessary to sorting the files.

Original File name Movie.mpg
After that I would have 01c0-0e17-44E2DD28FC010189-Movie.mpg

Those first 8 digits help me sort the correct files into folder's.
Example there will turn out to be about 4 separate files sometime's more that was mixed into one video.
The remaining digits put the video file back in order.
After thats done each folder would contain all the correct pieces of each of the video file's in order.
I then CD to that folder and
Code:
(ls | xargs cat) >

into one video file.

set_color

set_color(1)							       fish							      set_color(1)

NAME

       set_color - set_color - set the terminal color

set_color - set the terminal color
   Synopsis
       set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR]

   Description
       Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple,
       cyan, white and normal.

       o -b, --background Set the background color

       o -c, --print-colors Prints a list of all valid color names

       o -h, --help Display help message and exit

       o -o, --bold Set bold or extra bright mode

       o -u, --underline Set underlined mode

       o -v, --version Display version and exit

       Calling set_color normal will set the terminal color to whatever is the default color of the terminal.

       Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey
       font color, while set_color --bold white will result in a white font color.

       Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator.

       set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and
       incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of
       ncurses and recompile fish against it in order to fix this issue.
