Questions tagged [quoting]

The use of quotation marks (typically, `'` or `"`) to mark tokens as string literals or strings subject to interpolation, or to treat multiple whitespace-separated tokens as a single unit.

Use this tag for questions about the correct use of quotation marks in programming, with respect to:

  • how to use quotation marks to mark text as a literal not to be interpreted in any way.
  • how to use quotation marks to mark text as subject to string interpolation.
  • how to escape (encode) quotation marks inside text already enclosed in quotation marks.

Especially in shell programming, with respect to:

  • when what quotation marks are needed, and if quoting is needed at all, including quoting of individual characters with \.
  • how to use quoting to partition a list of tokens into distinct arguments that may have embedded whitespace.
  • when quotation marks are considered part of the input vs. recognized syntactically by the shell (quote removal).
