Instance Method Details

- (Object) alt_escape(cmdline)

Escape special characters used in most unix shells to use it, eg. with system().

This differs from Ruby's #escape in that it does not escape shell variables, e.g. $0.

def alt_escape(cmdline)
  cmdline.gsub(/([\\\t\| &`<>)('"])/) { |s| '\\' << s }
end

- (Object) dos_escape(cmdline)

Escape special character used in DOS-based shells.

TODO: How to integrate with rest of system?

  1. Use platform condition?

  2. Use separate dos_xxx methods?

  3. Put in separate PowerShellwords module?
