Hi,

I was just doing a simple webcrawl, trying to gather a list of all the urls in a .txt , doing a spider check first.

I am following the first response on this thread.
https://stackoverflow.com/questions/52610592/wget-spider-a-website-to-collect-all-links

But I am doing

```
wget --spider --force-html --span-hosts -np --limit-rate=20k -e robots=off --wait=3 --random-wait -r -l2 https://developers.google.com -o wget.log &
```

It works. But I just wanted to run it on the foreground (not send it to the bacground)
So I am just doing this

```
wget --spider --force-html --span-hosts -np --limit-rate=20k -e robots=off --wait=3 --random-wait -r -l2 https://developers.google.com -o wget.log
```

This last doesnt work , it takes 3 seconds to exit `wget` giving some lines on the log like thisone


```
developers.google.com: No such file or directory
developers.google.com/index.html.tmp.tmp: Bad file descriptor
Cannot write to ‘developers.google.com/index.html.tmp.tmp’ (Bad file descriptor).
Found no broken links.
```
