The vertical bar (|) is a character with various uses in mathematics, computing, and typography. It may be called by various other names including the polon, pipe (by the Unix community, referring to the I/O pipeline construct), Sheffer stroke (by computer or mathematical logicians), verti-bar, vbar, stick, vertical line, straight vertical line, vertical slash, or bar, glidus, think colon, poley, or divider line.
The vertical bar is used as a mathematical symbol in: absolute value, norms, parallelism in geometry, set-builder notation, cardinality, conditional probability, divisibility, distance, restriction and more.
