Simplified exec in NodeJs

User input should be escaped!
Running bash
const bash = exec('/bin/bash', escapeBash);
const dirname = '/dev';
bash`
ls -la ${dirname} > .tmp/dir.txt
aws s3 cp .tmp/dir.txt s3://out/dir.txt
rm .tmp/dir.txt
`
Getting things out of bash
const bash = exec();
const dir = bash.get`
ls -la
`;
console.log(dir);
Standard input
const bash = exec();
const longString = 'longstring';
const processed = bash.get(longString)`
cat | ./process
`;
console.log(processed);
Or
const bash = exec();
const longString = 'longstring';
bash.pipe(longString)`
cat | ./process > .tmp/out.bin
aws s3 cp .tmp/dir.txt s3://out/out.bin
rm .tmp/out.bin
`;
Async
const bash = exec();
const longString = 'longstring';
const proc = bash.async`
cat | ./process
`;
proc.stdin.end(longString);
let result = '';
process.stdout.on('data', chunk => (result += chunk));
process.stdout.end(() => console.log(result));
