Question

I remember that sometimes ago I was able to understand for which architecture a library (e.g. a .so or .a file) was built.

It was a shell command but now I cannot remember it.

Does somemone know it?

Thanks!

Answer 1

Maybe there is a better way, but generally the file command gives this information:

$ file /lib/libuuid.so.1.3.0
/lib/libuuid.so.1.3.0: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, stripped

You may also try readelf:

readelf -h /lib/libuuid.so.1.3.0
