This is for shell programming experts...
The code below works fine but...
It is UGLY, (just like me ;o)...
I need generate random length binary files on the fly, so to test I used a simple for loop to generate all of the _bytes_ from 0 to 255.
As you can see from the simple code I am doing it in three steps.
I have searched the WWW on how to generate random length binary files on the fly but nothing came useful at all...
So I am asking for help, here is the code and a copy of the results from the shell as comments in the code...
Can it be simplified? If so, point me in the right direction...
TIA, Bazza...
| Code: |
# !/bin/sh
for char in {0..255}
do
printf '\\\\x'"%02x" $char >> BinaryFile.txt
done
read somefile < BinaryFile.txt
printf "$somefile" > BinaryFile.dat
ls -al BinaryFile.*
hexdump -C BinaryFile.txt
hexdump -C BinaryFile.dat

You can read from /dev/urandom to get random bytes. For example, to create a file called "yourfile" in the current directory with 256 random bytes do:
| Code: | | head -c 256 </dev/urandom >yourfile |

Hi xenopeek...
I already know that as I use it for generating white noise sometimes using /dev/dsp but...
I need a random LENGTH of a binary file not a file of randomly generated bytes of any length...
I WILL know what is in the binary file but I will not know its length at run time.
For example the binary file may be 8192 bytes in length...
I may want to extract say 64 bytes from any section of it or 128 bytes from equispaced jumps inside this binary file... This is not my problem it is generating this known binary file from a text mode format... I want to be able to save my KNOWN binary file straight into binary and NOT have the text mode version of it generated too...
Does this make more sense...

Is this what you're looking for?
| Code: |
martyn@inspiron:~$ cat test.sh
#!/bin/sh
# zero the binary file
>Binaryfile.dat
# get random size, up to 100 chars
numchars=$[( $RANDOM % 100 )]
echo "Producing a file of $numchars chars"
for ((r=1;r<${numchars};r++))
do
char=`printf '\\\\x'"%02x" $r`
printf "$char" >> Binaryfile.dat
done
martyn@inspiron:~$ sh test.sh
Producing a file of 40 chars
martyn@inspiron:~$ hexdump -C Binaryfile.dat

Hi MBF...
Cool, the backticks, I forgot entirely about those and as soon as I saw them I immediately thought of AMIGA CLI...
This is more or less exactly what I want...
You are a star...
I have not tested it yet but from what I see it will do what I want...
Many thanks chap...
EDIT:-
Hi MBF
Those backticks did the trick. I am now scanning through any binary file and creating a new one in the modes described above selecting offset, jump and size...
Great stuff, many thanks matey...

Use $(command) instead of `command` - you'll find it much easier to understand when you look at your script in six months.
Also, the $(...) method can be nested which can be done with backticks but only with the application of seriously ugly amounts of leaning toothpicks. If you want your code to look that bad, you may as well start using Perl

Hi nelz...
> "...seriously ugly amounts of leaning toothpicks."
LOL!
I haven't done shell scripting for a long while and it amazes me how much I have forgotten...
I shall be calling on you guys again soon no doubt...
As for the backticks it all came flooding back from the AMIGA OS days and within an hour or so I am manipulating binary files for a project that will be released on here in the not too distant future...
;o)

So combining the $RANDOM bit, you can collapse the script to one command that does the same
| Code: | | head -c $[( $RANDOM % 100 )] </dev/urandom >Binaryfile.dat |
That line generates a file called Binaryfile.dat of random length, between 0 and 99 characters, and fills it with random bytes. |

Hi MBF...
Well here it is the DEMO using your backticks technique...
A known binary file and my wanted binary file.
Believe it or not my wanted file WILL become the _timebase_ of a shell AudioScope that I have already started...
I mentioned you in the comments... ;o)
Thanks a lot...
Watch out for wordwrapping, etc...
| Code: |
# !/bin/sh
#
# BFM.sh
# A very simple DEMO Binary File Manipulation shell code issued entirely as Public Domain.
#
# Apologies for any typos...
#
# This is a DEMO to show how to generate binaryfiles in the shell.
# I need this facility for a kids project I am doing. It will be posted onto here in
# the not too distant future...
#
# To run, ensure the script is executable and from a terminal type:-
#
# *****$ /absolute/path/to/BFM.sh<CR>
#
# And away you go...
#
# Many thanks to MartyBartFast of the Linux Format forums for reminding me of the backticks... ;o)
#
# Written so that kids and newbies can understand what is going on...
#
# $VER: BFM.sh_Version_0.00.10_Public_Domain_2013_B.walker_G0LCU.
#
# Enjoy finding simple solutions to often very difficult problems...
# These two files WILL be generated inside YOUR default /directory/drawer/folder/...
# Zero them as a starter JUST for this DEMO...
> SomeBinaryFile.dat
> MyBinaryFile.dat
# This loop is to give a usable 256 byte binary file only from 0x00 to 0xFF continuous...
clear
for character in {0..255}
do
# Note:- The backticks and the four escape characters are required...
char=`printf '\\\\x'"%02x" $character`
printf "$char" >> SomeBinaryfile.dat
done
# Do a hexadecimal dump to prove the file is binary and 256 bytes in size...
printf "\nOffset. Hexadecimal Dump. ASCII Dump.\n"
hexdump -C SomeBinaryFile.dat
# Now this EXAMPLE loop is the working loop. The three variables set the "start", (_offset_), of where you want
# your file to start, the "jump" between each _sample_ and the last_byte_limit to where you want to finish...
# IMPORTANT!!! There is NO error detection or correction in the code as it is a DEMO so don't come back and
# say that you can crash it, e.g. setting the "last_byte_limit" to -1 for example...
# Also although I am using a "for" loop for this DEMO you could select a single byte manually and code accordingly...
#
# The _variables_ for this DEMO. The jump is set to every seventh byte for this DEMO.
start_offset=4
jump=7
last_byte_limit=200
# _hexdump_ is used to select the byte(s) according to this DEMO "for" loop...
for subscript in $( seq $start_offset $jump $last_byte_limit )
do
number=`hexdump -n1 -s$subscript -v -e '1/1 "%u"' SomeBinaryFile.dat`
char=`printf '\\\\x'"%02x" $number`
printf "$char" >> MyBinaryFile.dat
done
# Now display it...
printf "\nOffset. Hexadecimal Dump. ASCII Dump.\n"
hexdump -C MyBinaryFile.dat
# A terminal window dump of what should occur...
#
# Offset. Hexadecimal Dump. ASCII Dump.
