shellUnquote

Unquotes a string as the shell (/bin/sh) would.

This function 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 g_shell_quote(). If it fails, it returns null and sets the error.

The @quoted_string need not actually contain quoted or escaped text; g_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.
