Full namespace name: clojure.java.shell

Overview

Conveniently launch a sub-process providing its stdin and
collecting its stdout

Public Variables and Functions

shfunction

Usage: (sh & args)

Passes the given strings to Runtime.exec() to launch a sub-process.

Options are

:in      may be given followed by any legal input source for
         clojure.java.io/copy, e.g. InputStream, Reader, File, byte[],
         or String, to be fed to the sub-process's stdin.
:in-enc  option may be given followed by a String, used as a character
         encoding name (for example "UTF-8" or "ISO-8859-1") to
         convert the input string specified by the :in option to the
         sub-process's stdin.  Defaults to UTF-8.
         If the :in option provides a byte array, then the bytes are passed
         unencoded, and this option is ignored.
:out-enc option may be given followed by :bytes or a String. If a
         String is given, it will be used as a character encoding
         name (for example "UTF-8" or "ISO-8859-1") to convert
         the sub-process's stdout to a String which is returned.
         If :bytes is given, the sub-process's stdout will be stored
         in a byte array and returned.  Defaults to UTF-8.
:env     override the process env with a map (or the underlying Java
         String[] if you are a masochist).
:dir     override the process dir with a String or java.io.File.

You can bind :env or :dir for multiple operations using with-sh-env
and with-sh-dir.

sh returns a map of
  :exit => sub-process's exit code
  :out  => sub-process's stdout (as byte[] or String)
  :err  => sub-process's stderr (String via platform default encoding)
