# sh/$ can't expand "~" so you must build it:

# (def key "D8E4DB18BF87FLEW7402BBE3AA91B16F4A65C4C9") # use your gpg key ID
(defn copy-and-encrypt-password-store [key-id]
    (with [out (file/open "pass-backup.tar.gz.gpg" :w)]
        (sh/$ tar -czf  $-$  ,(string (os/getenv "HOME") "/.password-store") | gpg --encrypt --recipient ,key-id  $>$  ,out)))

# tar -cz ~/.password-store/ | gpg --encrypt --recipient YOUR_KEY_ID > pass-backup.tar.gz.gpg

# sh/$'s contents are quasiquoted, allowing direct or string arguments
# so you need to unquote , variables:

(def out (file/open "trust-db.txt" :w))
(sh/$ "gpg" "--export-ownertrust"  $>$  ,out) # > requires an opened file object
(file/close out)

# note how > requires an opened file object
(with [out (file/open "trust-db.txt" :w)]
  (sh/$ gpg --export-ownertrust  $>$  ,out))
