Is there anything like file in shell for lisp to determine file type? If not, how do you determine file tpye?
In most case pathname-type is good enough, but sometimes you may run into some files doesn't have been correct named.

The functionality of file is available in libmagic:
As of version 4.00 of the Ian Darwin/Christos Zoulas version of file, the functionality of file is incorporated into a libmagic library that is accessible via C (and C-compatible) linking;[7][8] file is implemented using that library.
And there is a binding for Common Lisp.
I had to install libmagic-dev on my system, and then:
CL-USER> (ql:quickload :magicffi)
...
(:MAGICFFI)
CL-USER> (magicffi:pathname-mime #P"/bin/ls")
"application/x-sharedlib; charset=binary"
See MAGICFFI.
