I think the issue is that Runtime.exec doesn't start a shell, just a
subprocess, so things that are normally handled by the shell (like
redirection and pipes) doesn't work.
On
(execute "env | grep PATH")
I get "env: |: no such file or directory" - pipes and redirections are
passed as arguments to the first command rather than being handled by
the shell.

:in is the "standard in" for a command, but you haven't specified
which command.
If you use "sh" as the command you get a shell and can use normal
shell syntax for the :in parameter.
So this works:
user=> (sh "sh" :in "env | grep PATH")
"PATH=/usr/bin:/bin:/usr/sbin:/sbin\n"
user=> (sh "sh" :in "env > tmp.txt")
""

As far as I can tell it does - it executes both commands, but returns
only the result of the last one.
If you want both, wrap them in a list or vector:
(defn test-execute [ls-arg1 ls-arg2]
(list
(execute (str "ls -" ls-arg1))
(execute (str "ls -" ls-arg2))))
