Describe the bug

Many commands require passing data of arbitrary size as program args:

• cast abi-encode
• cast access-list
• cast call
• cast calldata
• cast disassemble
• cast estimate
• cast pretty-calldata
• cast publish
• cast rpc
• cast send
• cast wallet sign
• forge create
• forge script

Usually these are Solidity function arguments, but sometimes these are raw transaction payloads or RPC JSONs. The problem is that Linux (other OS-es probably too) puts a hard limit on the size of the program args, throwing Argument list too long if violated. For regular kernel builds it's just 128KB per arg, which for hex-encoded data halves the limit to just 64KB, it's very easy to hit it and there's no workaround.

There are a few approaches for passing arbitrarily-sized args without limitations:

• Stdin. Convenient to use, has no size limitations, but it'd put a hard limit of a single arbitrarily-sized arg per command, e.g. it may be tricky to support the interactive wallet.
• Files. Not very convenient to use, has no size limitations, wouldn't collide with any parameters.
• Enviroment variables. Rather convenient to use, but does have some OS-dependent limitations, wouldn't collide with any parameters.

Any of these solutions would need to work along the regular passing by args to keep the backward compatibility.
