| 5 | xversion \- determine which version of X is running |
|---|
| 6 | .SH SYNOPSIS |
|---|
| 7 | .B xversion |
|---|
| 8 | [ -r ] |
|---|
| 9 | .SH DESCRIPTION |
|---|
| 10 | .I Xversion |
|---|
| 11 | prints to standard output the major version number of the X server |
|---|
| 12 | running on screen 0 of the workstation. If the |
|---|
| 13 | .B -r |
|---|
| 14 | flag is specified, |
|---|
| 15 | .I xversion |
|---|
| 16 | will also print out the minor protocol revision number associated with |
|---|
| 17 | the X server. If |
|---|
| 18 | .I xversion |
|---|
| 19 | cannot make a connection to the server, it prints the text '?unknown'. |
|---|
| 20 | .PP |
|---|
| 21 | The format of the output string depends on whether the |
|---|
| 22 | .B -r |
|---|
| 23 | flag is specified. If it is not, the output string will just be a |
|---|
| 24 | number representing the major protocol revision. If the |
|---|
| 25 | .B -r |
|---|
| 26 | flag is specified, the output string is XnRn. For example, if the X |
|---|
| 27 | server that is currently running on display 0 is X11R3, the output |
|---|
| 28 | string will be "X11R3". |
|---|
| 29 | .PP |
|---|
| 30 | .I xversion |
|---|
| 31 | is intended principally as a tool to be used within shell scripts, |
|---|
| 32 | such as |
|---|
| 33 | .I xswitch. |
|---|
| 34 | .SH BUGS |
|---|
| 35 | The display name is hard-coded as 'unix:0'; i.e. the value of the |
|---|
| 36 | DISPLAY environment variable is ignored. |
|---|
| 37 | .PP |
|---|
| 38 | The output of the minor protocol revision number is only supported if |
|---|
| 39 | the current server is X11. If an X10 server is currently running, only |
|---|
| 40 | the major protocol revision number is printed. |
