Find if a binary is 32/64 bit

[Anil C. Sedha]

I have tried what, chatr, strings, file commands to find the bit version of a binary file, but have not been able to.

Is there something else to help me out.

Regards,
Anil

What is this binary file?
And what it returns for command file "your_binary_file"

It is an internal application binary. I need to know what bit version has it got compiled in. what library version is it running.

You should be able to figure this out based on the output of the 'file' command.

If file output is "PA RISC 1.1......" then it is definitely 32 bit.

If file output is "PA RISC 2.0......" then I believe it is still a 32-bit executable.

If file output is "ELF-64 executable object file....." then it is definitely a 64-bit executable file.

Since od does noet show both hex and ascii, what is the output of

# perl -0 -le'@x=split//,substr(<>,0,128);while(@y=map{ord}splice@x,0,16){$y=join"",map{$_<32||$_>0x7f?sprintf"{%x}",$_:chr$_}@y;print +(map{sprintf"%02x ",$_}@y),$y;print"\n"}' your_file

?

Besides file, I think you can find this out with chatr.
