Classes
| IOInstance | An instance of the IO class, for example in
|
| POpenCall | A system command executed via the IO.popen method. Signature: popen([env,] cmd, mode="r" [, opt]) -> io popen([env,] cmd, mode="r" [, opt]) {|io| block } -> obj IO.popen does different things based on the value of cmd: "-" : fork commandline : command line string which is passed to a shell [env, cmdname, arg1, ..., opts] : command name and zero or more arguments (no shell) [env, [cmdname, argv0], arg1, ..., opts] : command name, argv[0] and zero or more arguments (no shell) (env and opts are optional.) Examples: ruby IO.popen("cat foo.txt | tail") IO.popen({some_env_var: "123"}, "cat foo.txt | tail") IO.popen(["cat", "foo.txt"]) IO.popen([{some_env_var: "123"}, "cat", "foo.txt"]) IO.popen([["cat", "argv0"], "foo.txt"]) IO.popen([{some_env_var: "123"}, ["cat", "argv0"], "foo.txt"]) Ruby documentation: https://docs.ruby-lang.org/en/3.1/IO.html#method-c-popen
