# xinfo
A command line tool with no external dependencies to print information about an
X server instance.
## Building and running
To build the code in this repository, run
```console
$ make
```
The latter command produces the `xinfo` executable, which can be run to get
information about the X server running for the current session.
```console
$ ./xinfo
```
A different X display can be selected by setting the `DISPLAY` environment
variable such that
```console
$ DISPLAY=hostname:D.S ./xinfo
```
returns information about display `D` and screen `S` on host `hostname`.
## Sample output
Here is an example of the output produced by `xinfo`.
