TypeError: accounts is not iterable, how to iterate over shell output?

[kaihendry]

Assuming there are many several directories in stacks, how do I iterate over the ls output, like you would do in a while loop in bash?

#!/usr/bin/env zx

const accounts = await $`ls -d stacks/*`;

console.log(accounts);

for (const acc of accounts) {
  console.log(acc);
}

Use

await glob(…)

Doesn't work...

await glob($`find . -name "README.md"`)
Uncaught TypeError: Patterns must be a string or an array of strings

Please read the manual.

First, it seems you're missing an await inside glob(), but I get the same result even without the internal await.

Then, it seems that

> await glob('README.md', './*/README.md')

is the way, because:

• in

  await glob(await $`find . -name "README.md"`)

the find command gives the results to stdout, not into a variable, which you could then pass to glob.

• in

 var a = await $`find . -name "README.md"`
 console.log(a)

shows that a is undefined, thus bad result.
