// Credits to https://github.com/xxorax/node-shell-escape
// Uses easy safe set of characters which can be left unescaped to keep it readable.
// Every other character will be backslash-escaped
export default function shellEscape(value: string): string {
return `'${value.replace(/'/g, "'\\''")}'`
.replace(/^(?:'')+/g, '') // unduplicate single-quote at the beginning
.replace(/\\'''/g, "\\'") // remove non-escaped single-quote if there are enclosed between 2 escaped
return value.replace(/([^a-zA-Z0-9,._+:@%/-])/gm, '\\$1')
