Hi utz and Brandon, > (capture ,(string-append "docker inspect " str))) doesn't work because of the same reason that you expressed. You would get "quasiquote not found" from the shell.
As a workaround, execute procedure might be used straightly. (define (inspect str) (execute (list (string-append "docker inspect " str)) 'verbose: #t )) Cheers, Am Fr., 10.
