Specify the Directory of a Shell Command

Clojure gives us access to Java's shell capabilities through clojure.java.shell. For instance, if you want to list the contents of your project's directory, you can issue an ls command:

> (clojure.java.shell/sh "ls")
; {:exit 0,
;  :out "LICENSE\nREADME.md\ndoc\nproject.clj\nresources\nsrc\ntarget\ntest\n",
;  :err ""}

The default will always be to execute the command in the directory of the containing project. It is likely that you'd like to specify a different directory though. There is a function for that:

(clojure.java.shell/with-sh-dir "some/dir" (clojure.java.shell/sh "ls"))

Or more concisely, you can specify the directory as part of the sh function:

(clojure.java.shell/sh "ls" :dir "some/dir")
