I want to read help for clisp function from REPL or just from shell. I found (symbol-plist) function for this which give this:

(symbol-plist 'bit)
(SYSTEM::TYPE-SYMBOL #<COMPILED-FUNCTION SYSTEM::TYPE-SYMBOL-BIT>
 SYSTEM::SETF-EXPANDER SYSTEM::STORE SYSTEM::DOC
 (CLHS "Body/any_bit.html" SYSTEM::FILE
  ((DEFSETF #P"/build/buildd/clisp-2.49/debian/build/places.fas" 941 941))))

but it's not so useful info in order to understand how does (bit) works?

So are there any manuals and documentation for clisp function something like man in shell?

Here, this may be of interest. Below is a short extract:

[Function] bit bit-array &rest subscripts sbit simple-bit-array &rest subscripts

bit is exactly like aref but requires an array of bits, that is, one of type (array bit). The result will always be 0 or 1. sbit is like bit but additionally requires that the first argument be a simple array (see section 2.5). Note that bit and sbit, unlike char and schar, allow the first argument to be an array of any rank.

Bit Function clisp

Also, this is a huge index of links to appropriate section(s) of the clisp manual.
