Usage:

English

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.

Arithmetic

A solidus is used in to separate numerator and denominator in a vulgar fraction or as a division operator in general.

3/8 – three eighths

x = a / bx equals a divided by b

Computing

Usually called a slash or sometimes, unnecessarily, a forward slash, / is used to separate directory or names in Unix file paths and in URLs.

This is in contrast to the backslash \ which is path delimiter on Microsoft Windows systems. Windows uses the backslash rather than the slash because in the early days of MS-DOS -- before directories were supported! -- the slash was chosen as the command-line option indicator:

dir /w /ogn c:\windows\

Other

Before decimalisation[?] in the UK, / was used to separate pounds, shillings, and pence values.

2/6 – two shillings and six pence
10/- – ten shillings
1/19/11 – one pound, nineteen shillings, and eleven pence

In computer programming, the solidus corresponds to Unicode and ASCII character 47, or 0x002F.
