Function glib::shell_unquote

pub fn shell_unquote<P: AsRef<OsStr>>(
    quoted_string: P
) -> Result<OsString, Error>

Unquotes a string as the shell (/bin/sh) would. Only handles quotes; if a string contains file globs, arithmetic operators, variables, backticks, redirections, or other special-to-the-shell features, the result will be different from the result a real shell would produce (the variables, backticks, etc. will be passed through literally instead of being expanded). This function is guaranteed to succeed if applied to the result of shell_quote(). If it fails, it returns None and sets the error. The quoted_string need not actually contain quoted or escaped text; shell_unquote() simply goes through the string and unquotes/unescapes anything that the shell would. Both single and double quotes are handled, as are escapes including escaped newlines. The return value must be freed with g_free(). Possible errors are in the G_SHELL_ERROR domain.

Shell quoting rules are a bit strange. Single quotes preserve the literal string exactly. escape sequences are not allowed; not even ' - if you want a ’ in the quoted text, you have to do something like ‘foo’'‘bar’. Double quotes allow $, `, “, , and newline to be escaped with backslash. Otherwise double quotes preserve things literally.
