Hi all,
Does anybody know or guide me on how to remove the first N bytes and the last N bytes from a binary file? Is there any AWK or SED or any command that I can use to achieve this?
Your help is greatly appreciated!!

Hello,
I have come across the necessity for me to deal with binary sequences and I had a few questions.
1- Does any UNIX scripting language provide any tool or command for converting text data to binary sequences? Example of binary sequence: "0x97 0x93 0x85 0x40 0xd5 0xd6 0xd7"
2- If I want... (2 Replies)

first block: ASDFGHJKL
1nd block: SDFGHJKLQ
What I have so far only gives me the first block, can anyone please explain why?

This is part of a large text file I need to separate out.
I'd like some help to build a shell script that will extract the text between sets of dashed lines, write that to a new file using the whole or part of the first text string as the new file name, then move on to the next one and... (7 Replies)
The title is clear: why does ext3 allocate 8 blocks for files that are few bytes long?
If I create a file named "test", put a few chars in it, and then I run:
stat test
I get that "Blocks: 8"
I searched in the web and found that ext does that, it allocates 8 blocks even if It doesn't need... (4 Replies)

vcatbands
vcatbands(1Vi)vcatbands(1Vi)NAME
vcatbands - concatenate image bands into a single image
SYNOPSIS
vcatbands [-option ...] [infile ...] [> outfile]
DESCRIPTION
vcatbands concatenates one or more images to produce a single, multi-band image. All images read from all input files are combined to pro-
duce a single image, which is written to the output file.
The input images must all have the same number of rows, number of columns, and pixel representation.
COMMAND LINE OPTIONS
vcatbands accepts the following options:
-help Print a message describing options.
-in infile ... Specifies one or more Vista data files containing images.
-out outfile Specifies where to write the output as a Vista data file.
-name name Specifies the name to be given the created image. Default: ``image''.
-frame_interp none
-viewpoint_interp none | stereo_pair
-color_interp none | rgb
-component_interp none | complex | gradient | intensity | orientation
Specify values for band interpretation attributes given to the new image. All default to none.
-nframes nframes
-nviewpoints nviewpoints
-ncolors ncolors
-ncomponents ncomponents
Specify the number of frames, viewpoints, colors, and components represented by bands of the new image. If not specified
nframes is deduced from the number of bands in the image; the others have defaults based on what the various -..._interp
options have specified.
Input files can be specified on the command line or allowed to default to the standard input stream. The output file can be specified by
the -out option or allowed to default to the standard output stream.
SEE ALSO vcat(1Vi), VImage(3Vi), Vista(7Vi)NOTES
All input files are read before the output file is opened and written.
