Pipe stdin to, or stdout from, a UNIX shell command. Pipe treats the shell command as if it were a UnixFILE, and returns nil when done. See UnixFILE for details of the access methods. Pipe must be explicitly closed. Do not rely on the garbage collector to do this for you!
| commandLine |
A String representing a valid shell command. |
| mode |
A String representing the mode. Valid modes are "w" (pipe to stdin) and "r" (pipe from stdout). |
| args |
A SequenceableCollection containining strings where the first string is the path to the executable to be run and all other strings are passed as arguments to the executable. This method starts the process directly without using a shell. |
| mode |
A String representing the mode. Valid modes are "w" (pipe to stdin) and "r" (pipe from stdout). |
Open the file.
| commandLine |
A command line String passed to popen. |
| mode |
A String passed to popen, so should be one of: "r","w" |

Closes the pipe, waiting for the command to finish. You must do this explicitly before the Pipe object is garbage collected.
The exit status of the command (an Integer).
// this pipes in stdout from ls(var p, l;p = Pipe.new("ls -l", "r"); // list directory contents in long formatl = p.getLine; // get the first linewhile({l.notNil}, {l.postln; l = p.getLine; }); // post until l = nilp.close; // close the pipe to avoid that nasty buildup)without using a shell:
