Shellwords
shellescape(str)private
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.
