If you have the program in C to process data, going to bash is like swapping a large truck for a turtle. Bash will be orders of magnitude slower, and you will have to take a lot of care to pipe data all over awk, sed, tr and the like. Bash is a terrible choice, python (or perl, or PHP) would be faster. Way faster.

How about ihex or srec?

Hello All, I am writing a bourne shell script, to read a binary file as input and take action depending on the contents of the file.
The file is a mixture of ASCII and binary codes (such as ASCII filed lengths and flags).
I have the processing already done in C. I would like to convert it to a bourne shell.
Does anyone have any suggestions on what combination of tools I may be able to use?
If you're only trying to look at the ASCII data (and trying to process binary data in Bash seems like a poor idea), then you may want to look at the "strings" command:
$ strings $(which ls)
"strings" is part of the binutils package on Debian.
