A Comprehensive Overview of Common Go Tools and Commands

This article provides a concise introduction to various Go (Golang) command‑line tools, their usage scenarios, and common flags. It covers official Go commands such as go help , go get , go build , go install , go fmt / gofmt , go env , go test , and the extensive go tool suite (e.g., go tool pprof , go tool trace , go tool compile , go tool vet , go tool doc , etc.). It also lists useful third‑party utilities for debugging, testing, code quality, and performance analysis, including Delve, goconvey, goleak, go‑wr​k, go‑swagger, staticcheck, and many others.

Official Go Commands

go help <command> displays help for a specific subcommand. Example:

go help get

go get downloads or updates a module and its dependencies.

go get -u "github.com/VictoriaMetrics/fastcache"

go build compiles packages and their dependencies. Use -x to see the compilation steps.

go build -x > result 2>&1

go install builds and installs a package, similar to go build but also copies the binary to $GOPATH/bin .

go fmt / gofmt formats source files according to the official Go style.

gofmt -s -w *.go

go env prints Go environment variables; you can set them with go env -w .

go env -w GOPROXY="https://goproxy.com,direct"

go test runs tests for a package. Coverage can be generated with -coverprofile and visualized via go tool cover .

go test -coverprofile=cover.out
go tool cover -html=cover.out -o coverage.html

The go tool Suite

Various low‑level utilities are available under go tool :

go tool pprof – performance profiling.

go tool trace – execution tracing.

go tool compile – compile a Go file to assembly ( -S ).

go tool vet / go vet – static analysis for common mistakes.

go tool doc – display documentation for Go identifiers.

go tool addr2line – translate program addresses to source locations.

go tool cover – generate HTML coverage reports.

go tool dist – manage Go distribution builds.

go tool fix – automatically update code to newer language versions.

go tool link – link object files into an executable.

go tool nm – list symbols in a binary.

go tool objdump – disassemble binaries.

go tool pack – create static libraries.

go tool test2json – convert test output to JSON.

Third‑Party Tools

delve – interactive debugger for Go programs.

goconvey – BDD‑style testing framework with web UI.

goleak – detect goroutine leaks.

go‑wrk – HTTP load testing tool.

go‑swagger – generate and validate Swagger/OpenAPI specs.

staticcheck – advanced static analysis (linting, bug detection).

goconst – find repeated string literals to replace with constants.

gocyclo – measure cyclomatic complexity of functions.

deadcode – detect unused code.

misspell – spell‑checking for source files.

revive – fast, configurable linter (alternative to golint).

gocode – code completion for editors like Vim.

godoctor – code refactoring assistance.

gops – inspect Go processes (memory, stack, etc.).

gotype – semantic analysis of Go code.

go‑mod family – module management (init, tidy, vendor, graph, verify, why, download, etc.).
