shellescape

Importance_2
shellescape(str) public

Escapes a string so that it can be safely used in a Bourne shell command line.

Note that a resulted string should be used unquoted and is not intended for use in double quotes nor in single quotes.

open("| grep #{Shellwords.escape(pattern)} file") { |pipe|
  # ...
}

String#shellescape is a shorthand for this function.

open("| grep #{pattern.shellescape} file") { |pipe|
  # ...
}

It is caller’s responsibility to encode the string in the right encoding for the shell environment where this string is used. Multibyte characters are treated as multibyte characters, not bytes.
