Function escape_for_double_quotes 

pub fn escape_for_double_quotes(value: &str) -> String

Escape a value so it can sit inside "..." as literal text.

Backslash, dollar, backtick and double quote are the only characters the shell still interprets inside double quotes, so escaping them makes the value literal - the inner program (e.g. bash -c) sees the original text.

Examples

use command_stream::quote::escape_for_double_quotes;

assert_eq!(escape_for_double_quotes("plain text"), "plain text");
assert_eq!(escape_for_double_quotes("$HOME"), "\\$HOME");
