[OCLUG-Tech] 64 bit executable check

["Prof. John C Nash" <nashjc [ at ] uottawa [ dot ] ca>]

With a colleague I've been building some statistical tools for Lin and Win. We want 64 
bit. Does anyone know of a quick check to see if a binary is 64 bit. I think there should 
be something like

    checkbin myfile

that will return the type e.g., ELF 32, ELF 64 etc.

Of course, we'd like to find Win equivalent too. But for starters a Linux tool would be 
helpful.

I've found it difficult to come up with search terms that don't find all sorts of 
extraneous material and nothing of interest.

Cheers, JN
