<!--{ "Title": "Command Documentation", "Path": "/doc/cmd" }--> <p> There is a suite of programs to build and process Go source code. Instead of being run directly, programs in the suite are usually invoked by the <a href="/cmd/go/">go</a> program. </p> <p> The most common way to run these programs is as a subcommand of the go program, for instance as <code>go fmt</code>. Run like this, the command operates on complete packages of Go source code, with the go program invoking the underlying binary with arguments appropriate to package-level processing. </p> <p> The programs can also be run as stand-alone binaries, with unmodified arguments, using the go <code>tool</code> subcommand, such as <code>go tool vet</code>. This style of invocation allows, for instance, checking a single source file rather than an entire package: <code>go tool vet myprogram.go</code> as compared to <code>go vet mypackage</code>. Some of the commands, such as <code>yacc</code>, are accessible only through the go <code>tool</code> subcommand. </p> <p> Finally the <code>fmt</code> and <code>godoc</code> commands are installed as regular binaries called <code>gofmt</code> and <code>godoc</code> because they are so often referenced. </p> <p> Click on the links for more documentation, invocation methods, and usage details. </p> <table class="dir"> <tr> <th>Name</th> <th> </th> <th>Synopsis</th> </tr> <tr> <td><a href="/cmd/go/">go</a></td> <td> </td> <td> The <code>go</code> program manages Go source code and runs the other commands listed here.
