sh

A shell parser, formatter, and interpreter. Supports POSIX Shell, Bash, and mksh. Requires Go 1.16 or later. To parse shell scripts, inspect them, and print them out, see the syntax examples. For high-level operations like performing shell expansions on strings, see the shell examples. shfmt formats shell programs. See canonical.sh for a quick look at its default style. shfmt formats shell programs. If the only argument is a dash (-) or no arguments are given, standard input will be used. If a given path is a directory, all shell scripts found under that directory will be used. When indexing Bash associative arrays, always use quotes. The static parser will otherwise have to assume that the index is an arithmetic expression. Some builtins like export and let are parsed as keywords. A subset of the Go packages are available as an npm package called mvdan-sh.
