797 Octave waits until it exits. If the @var{type} argument is omitted, a\n\ |
| 3301 | 798 value of @code{\"sync\"} is assumed.\n\ |
| 2083 | 799 \n\ |
| 3301 | 800 If two input arguments are given (the actual value of\n\ |
| 801 @var{return_output} is irrelevant) and the subprocess is started\n\ | |
| 802 synchronously, or if @var{system} is called with one input argument and\n\ | |
| 803 one or more output arguments, the output from the command is returned.\n\ | |
| 5097 | 804 Otherwise, if the subprocess is executed synchronously, its output is\n\ |
| 2321 | 805 sent to the standard output. To send the output of a command executed\n\ |
| 3301 | 806 with @var{system} through the pager, use a command like\n\ |
| 2321 | 807 \n\ |
| 3301 | 808 @example\n\ |
| 809 disp (system (cmd, 1));\n\ | |
| 810 @end example\n\ | |
| 2321 | 811 \n\ |
| 3301 | 812 @noindent\n\ |
| 2321 | 813 or\n\ |
| 814 \n\ | |
| 3301 | 815 @example\n\ |
| 816 printf (\"%s\n\", system (cmd, 1));\n\ | |
| 817 @end example\n\ | |
| 818 \n\ | |
| 5659 | 819 The @code{system} function can return two values. The first is the\n\ |
| 820 exit status of the command and the second is any output from the\n\ | |
| 821 command that was written to the standard output stream. For example,\n\ | |
| 3301 | 822 \n\ |
| 823 @example\n\ | |
| 5717 | 824 [status, output] = system (\"echo foo; exit 2\");\n\ |
| 3301 | 825 @end example\n\ |
| 826 \n\ | |
| 827 @noindent\n\ | |
