GQuark shellErrorQuark()
bool shellParseArgv(string commandLine, string[] argvp)

Parses a command line into an argument vector, in much the same way the shell would, but without many of the expansions the shell would perform (variable expansion, globs, operators, filename expansion, etc. are not supported). The results are defined to be the same as those you would get from a UNIX98 /bin/sh, as long as the input contains none of the unsupported shell expansions. If the input does contain such expansions, they are passed through literally. Possible errors are those from the G_SHELL_ERROR domain. Free the returned vector with g_strfreev().

string shellQuote(string unquotedString)

Quotes a string so that the shell (/bin/sh) will interpret the quoted string to mean unquoted_string. If you pass a filename to the shell, for example, you should first quote it with this function. The return value must be freed with g_free(). The quoting style used is undefined (single or double quotes may be used).

string shellUnquote(string quotedString)

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 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.
