| 9 | .SH DESCRIPTION |
| 10 | The |
| 11 | .B xscsize |
| 12 | program interrogates an X display and writes the size of the root |
| 13 | window to standard output in the form of a shell variable assignment |
| 14 | statement. The dimensions are returned in the |
| 15 | .B XWIDTH |
| 16 | and |
| 17 | .B XHEIGHT |
| 18 | variables. |
| 19 | .PP |
| 20 | Command line options can be used to force output in either Bourne or C |
| 21 | shell syntax. In the absence of any explicit instructions, |
| 22 | .B xscsize |
| 23 | looks at the |
| 24 | .B SHELL |
| 25 | environment variable to help make its mind up. |
| 26 | .PP |
| 27 | Typical use would be something like |
| 28 | .RS 5 |
| 29 | .ft B |
| 30 | .nf |
| 31 | eval `xscsize` |
| 32 | .ft R |
| 33 | .fi |

| 39 | .TP 5 |
| 40 | .B \-c |

| 43 | .TP 5 |
