In the first example, is there any need for the first three lines where the 'tty' command is demonstrated? It seems to have no relation to the article and I would suggest it be removed. Thecoshman (talk) 09:49, 17 September 2012 (UTC)

Is there a relation between Unix's wall, and the "wall" on Facebook and some other social networking sites (such as fruhead.com) - a forum for public messages?

- "mshenrick: is it just me, or does the #facebook write on wall anything to do with the unix / linux commands write and wall?"
- the developers may have used unix/linux and put in a subtle nod to it writing on a wall!
