for details.

Usage: solc [options] [input_file...]
Compiles the given Solidity input files (or the standard input if none given or
"-" is used as a file name) and outputs the components specified in the options
at standard output or in files in the output directory, if specified.
Imports are automatically read from the filesystem, but it is also possible to
remap paths using the context:prefix=path syntax.
Example:
solc --bin -o /tmp/solcoutput dapp-bin=/usr/local/lib/dapp-bin contract.sol

General Information:
  --help               Show help message and exit.
  --version            Show version and exit.
  --license            Show licensing information and exit.
  --input-file arg     input file

Input Options:
  --base-path path     Use the given path as the root of the source tree
                       instead of the root of the filesystem.
  --include-path path  Make an additional source directory available to the
                       default import callback. Use this option if you want to
                       import contracts whose location is not fixed in relation
                       to your main source tree, e.g. third-party libraries
                       installed using a package manager. Can be used multiple
                       times. Can only be used if base path has a non-empty
                       value.
  --allow-paths path(s)
                       Allow a given path for imports. A list of paths can be
                       supplied by separating them with a comma.
  --ignore-missing     Ignore missing files.
  --error-recovery     Enables additional parser error recovery.

Output Options:
  -o [ --output-dir ] path
                       If given, creates one file per output component and
                       contract/file at the specified directory.
  --overwrite          Overwrite existing files (used together with -o).
  --evm-version version (=paris)
                       Select desired EVM version. Either homestead,
                       tangerineWhistle, spuriousDragon, byzantium,
                       constantinople, petersburg, istanbul, berlin, london or
                       paris.
  --experimental-via-ir
                       Deprecated synonym of --via-ir.
  --via-ir             Turn on compilation mode via the IR.
  --revert-strings debug,default,strip,verboseDebug
                       Strip revert (and require) reason strings or add
                       additional debugging information.
  --debug-info arg (=ast-id,location,snippet)
                       Debug info components to be included in the produced EVM
                       assembly and Yul code. Value can be all, none or a
                       comma-separated list containing one or more of the
                       following components: ast-id, location, snippet.
  --stop-after stage   Stop execution after the given compiler stage. Valid
                       options: "parsing".

Alternative Input Modes:
  --standard-json      Switch to Standard JSON input / output mode, ignoring
                       all options. It reads from standard input, if no input
                       file was given, otherwise it reads from the provided
                       input file. The result will be written to standard
                       output.
  --link               Switch to linker mode, ignoring all options apart from
                       --libraries and modify binaries in place.
  --assemble           Switch to assembly mode, ignoring all options except
                       --machine, --yul-dialect, --optimize and
                       --yul-optimizations and assumes input is assembly.
  --yul                Switch to Yul mode, ignoring all options except
                       --machine, --yul-dialect, --optimize and
                       --yul-optimizations and assumes input is Yul.
  --strict-assembly    Switch to strict assembly mode, ignoring all options
                       except --machine, --yul-dialect, --optimize and
                       --yul-optimizations and assumes input is strict
                       assembly.
  --import-ast         Import ASTs to be compiled, assumes input holds the AST
                       in compact JSON format. Supported Inputs is the output
                       of the --standard-json or the one produced by
                       --combined-json ast
  --lsp                Switch to language server mode ("LSP"). Allows the
                       compiler to be used as an analysis backend for your
                       favourite IDE.

Assembly Mode Options:
  --machine evm,ewasm  Target machine in assembly or Yul mode.
  --yul-dialect evm,ewasm
                       Input dialect to use in assembly or yul mode.

Linker Mode Options:
  --libraries libs     Direct string or file containing library addresses.
                       Syntax: <libraryName>=<address> [, or whitespace] ...
                       Address is interpreted as a hex string prefixed by 0x.

Output Formatting:
  --pretty-json        Output JSON in pretty format.
  --json-indent N (=2) Indent pretty-printed JSON with N spaces. Enables
                       '--pretty-json' automatically.
  --color              Force colored output.
  --no-color           Explicitly disable colored output, disabling terminal
                       auto-detection.
  --error-codes        Output error codes.

                       output.

Optimizer Options:
  --optimize           Enable bytecode optimizer.

                       The number of runs specifies roughly how often each
                       opcode of the deployed code will be executed across the
                       lifetime of the contract. Lower values will optimize

                       optimize more for high-frequency usage.

                       Forces yul optimizer to use the specified sequence of

Model Checker Options:
  --model-checker-contracts default,<source>:<contract> (=default)
                       Select which contracts should be analyzed using the form
                       <source>:<contract>.Multiple pairs <source>:<contract>
                       can be selected at the same time, separated by a comma
                       and no spaces.
  --model-checker-div-mod-no-slacks
                       Encode division and modulo operations with their precise
                       operators instead of multiplication with slack
                       variables.
  --model-checker-engine all,bmc,chc,none (=none)
                       Select model checker engine.
  --model-checker-ext-calls untrusted,trusted (=untrusted)
                       Select whether to assume (trusted) that external calls
                       always invoke the code given by the type of the
                       contract, if that code is available.
  --model-checker-invariants default,all,contract,reentrancy (=default)
                       Select whether to report inferred contract inductive
                       invariants. Multiple types of invariants can be selected
                       at the same time, separated by a comma and no spaces. By
                       default no invariants are reported.
  --model-checker-show-unproved
                       Show all unproved targets separately.
  --model-checker-solvers cvc4,eld,z3,smtlib2 (=z3)
                       Select model checker solvers.
  --model-checker-targets default,all,constantCondition,underflow,overflow,divByZero,balance,assert,popEmptyArray,outOfBounds (=default)
                       Select model checker verification targets. Multiple
                       targets can be selected at the same time, separated by a
                       comma and no spaces. By default all targets except
                       underflow and overflow are selected.
  --model-checker-timeout ms
                       Set model checker timeout per query in milliseconds. The
                       default is a deterministic resource limit. A timeout of
                       0 means no resource/time restrictions for any query.
