你也可以在Ruby的subversion存储库(这是GPLv2)的主干中从shellwords.rb复制你想要的东西:
def shellescape(str)
# An empty argument will be skipped, so return empty quotes.
return "''" if str.empty?
str = str.dup
# Process as a single byte sequence because not all shell
# implementations are multibyte aware.
str.gsub!(/([^A-Za-z0-9_\-.,:\/@\n])/n, "\\\\\\1")
# A LF cannot be escaped with a backslash because a backslash + LF
# combo is regarded as line continuation and simply ignored.
str.gsub!(/\n/, "'\n'")
return str
end
