A solidus, oblique or slash, /, is a punctuation mark. It is also called a diagonal, separatrix, shilling mark, stroke, virgule, or slant.
The most common use is to replace the hyphen to make clear a strong joint between words or phrases, such as "the Ernest Hemingway/William Faulkner generation".
For a specialized use of the slash in the titles of fan fiction stories, see slash fiction.
A virgule is used to separate the numerator and denominator in a vulgar fraction, or as a division operator in general.
Note that the special character Fraction slash U+2044, character ⁄ (the solidus or shilling mark proper), can be used instead of a virgule, and is preferred whenever possible. It is also found in many legacy Apple Macintosh character sets. Systems capable of fine typography should display the result as a true fraction with smaller numbers. Unicode also distinguishes the Division Slash U+2215 (∕) which may be more oblique than the normal solidus character.
The slash is used to separate directory or names in Unix file paths and in URLs.
It is sometimes called a "forward slash" to contrast with the backslash \ which is the path delimiter on MS-DOS and Microsoft Windows systems. Windows uses the backslash rather than the slash because in the early days of DOS — before directories were supported — the slash was chosen as the command-line option indicator:
In computer programming, the solidus corresponds to Unicode and ASCII character 47, or 0x002F.
The slash is also used in BambooWeb for sub-pages. For example: BambooWeb:Requested_articles/science or September 16, 2003.
Before decimalisation in the UK, / was used to separate pounds, shillings, and pence values.
In the UK, the usual term for the mark is an oblique, although slash is gaining currency with increasing use of computers.
