ANSI C quoting

ANSI-C quoting allows for backslash-escaped characters to be interpreted according to the ANSI C standard, enabling special characters like newlines and tabs to be represented within strings. This is done using the syntax $‘string’, where escape sequences are processed accordingly.

$'string'

How It Works

When using ANSI-C quoting, the following escape sequences are processed:

• Newline: `\
• Tab: \t
• Backslash: \
• Octal values: \nnn (where nnn is one to three octal digits)
• Hexadecimal values: \xnn (where nn is one to three hexadecimal digits)

Examples

Here’s a table illustrating how ANSI-C quoting works:

Command Result

echo $‘Hello\nWorld’ Prints: Hello (new line) World echo $‘Tab:\tIndented’ Prints: Tab: (tab space) Indented echo $‘Quote: ’ Prints: Quote: ’ `
