| | 11 | The |
| | 12 | .B xscsize |
| | 13 | program interrogates an X display and writes the size of the root |
| | 14 | window to standard output in the form of a shell variable assignment |
| | 15 | statement. The dimensions are returned in the |
| | 16 | .B XWIDTH |
| | 17 | and |
| | 18 | .B XHEIGHT |
| | 19 | variables. |
| | 20 | .PP |
| | 21 | Command line options can be used to force output in either Bourne or C |
| | 22 | shell syntax. In the absence of any explicit instructions, |
| | 23 | .B xscsize |
| | 24 | looks at the |
| | 25 | .B SHELL |
| | 26 | environment variable to help make its mind up. |

| | 29 | .RS 5 |
