794 Octave waits until it exits. If the @var{type} argument is omitted, a\n\ |
| 3301 | 795 value of @code{\"sync\"} is assumed.\n\ |
| 2083 | 796 \n\ |
| 3301 | 797 If two input arguments are given (the actual value of\n\ |
| 798 @var{return_output} is irrelevant) and the subprocess is started\n\ | |
| 799 synchronously, or if @var{system} is called with one input argument and\n\ | |
| 800 one or more output arguments, the output from the command is returned.\n\ | |
| 5097 | 801 Otherwise, if the subprocess is executed synchronously, its output is\n\ |
| 2321 | 802 sent to the standard output. To send the output of a command executed\n\ |
| 3301 | 803 with @var{system} through the pager, use a command like\n\ |
| 2321 | 804 \n\ |
| 3301 | 805 @example\n\ |
| 806 disp (system (cmd, 1));\n\ | |
| 807 @end example\n\ | |
| 2321 | 808 \n\ |
| 3301 | 809 @noindent\n\ |
| 2321 | 810 or\n\ |
| 811 \n\ | |
| 3301 | 812 @example\n\ |
| 813 printf (\"%s\n\", system (cmd, 1));\n\ | |
| 814 @end example\n\ | |
| 815 \n\ | |
| 5659 | 816 The @code{system} function can return two values. The first is the\n\ |
| 817 exit status of the command and the second is any output from the\n\ | |
| 818 command that was written to the standard output stream. For example,\n\ | |
| 3301 | 819 \n\ |
| 820 @example\n\ | |
| 5717 | 821 [status, output] = system (\"echo foo; exit 2\");\n\ |
| 3301 | 822 @end example\n\ |
| 823 \n\ | |
| 824 @noindent\n\ | |
| 825 will set the variable @code{output} to the string @samp{foo}, and the\n\ | |
| 826 variable @code{status} to the integer @samp{2}.\n\ | |
