| + | You can copy this file to your bin directory and use it on the command line with: | ||
| - | in bash that first uploads the file, then posts it to the room. I've named it matrix_cp as it basically lets you copy a image to the room: | + | <code bash> |
| - | <code bash matrix_cp.sh> | + | matrix_cp /tmp/example.jpg glasgow "This is an example image" |
| - | #!/bin/bash | + | |

| - | # ./matrix_cp filename room_id alt_text | + | |
