EDIT:
This is a hexdump -C of the file...
Found the sections that newlines could be coded for...
The 4 examples are the length of each ASCII character block and 2 are ascii characters too!
I have not bothered to do the others but just look at the character before each __text__ block.
Thanks wisecracker, it's wonderful, magic, i would loop the file char by char, but i hadn't the trick for.
I add this to your fabulous code for separate and filter the text:
I thought of using od something like this and filtering out the correct numbers.
(This is a 512 byte test binary file of mine, OSX 10.7.5, default bash terminal.)
Hi wisecracker, i have seen the trick with od and his decimal output, but i prefer the command hexdump (no loop)
thanx for the trick with loop for understanding me the read byte by byte of a binary file.
I have a binary file with all content is text, i want convert this binary to a regular file because i want to parse it.
Thx.

Looks like that some of our log files are set as binary:

I am struck up with a problem and that is with output redirection.
I used all the ways for the redirection of the output of c binary to a file, still it is failing.
Here are the different ways which I have used:
./a.out | tee -a /root/tmp.txt 2>&1
./a.out | tee -a /root/tmp.txt 1>&1

I am using grep to match a pattern, but the output is strange.
$ grep -r -o "pattern" *
Gives me:
Binary file foo1 matches
Binary file foo2 matches
Binary file foo3 matches
To find the lines before/after, I then have to use the following on each file:
$ strings foo1 | grep -A1 -B1... (0 Replies)
