What word or phrase does your mother always say?
The character "|", ASCII code 124.
Common names: bar; or; or-bar; v-bar; pipe; vertical bar. Rare: ITU-T: vertical line; gozinta; thru; pipesinta; INTERCAL: spike.
"Pipe", "gozinta", "thru" and "pipesinta" refer to the use of "|" in Unix shells to create a pipe.
Some keyboards show both a solid vertical bar (code 124) and a broken vertical bar (code 166).
[Does anyone call either kind of vertical bar "pling"? Other codes?]
