A: How to overwrite each line of STDOUT with the next one? Instead of having new stdout lines overwrite the previous one, it seems better to specify that old stdout lines should be overwritten by anything that comes after them. This has the benefit that stdout cannot overwrite stderr (or anything else that goes in the tty). ```sh #!/bin/sh setterm ... (more) |

Thanks Kamil! Makes sense.
@quasimodo, no, that would have the same problems as my suggestion. (more) |

Why do you need the `echo x` trick? What happens without it?
I think this would be simpler:
```sh
...
lines="$(tee /dev/tty | tail -n "$n")"
leave
printf '%s\n' "$lines"
```
Am I missing anything?

What's the reason for redirecting the whole `enter()` and `leave()` functions to /dev/tty?
Do both setterm(1) and tput(1) need to be redirected? Or is it only necessary to redirect one of them? (more) |

Thanks!
Just a minor nitpick: `$COLUMNS` is not available (unless I export it manually). I replaced it with `tput cols`:
```sh
$ cat /usr/local/bin/ovr
#!/bin/sh
sed "s/^\(.\{,$(tput cols)\}\).*$/\1/;2,\$s/^/\x1B[1A\x1B[K/";
```

A: Ergonomic way to search man pages Unix filters are quite handy. First of all, you can get an index of any manual page with a simple grep(1): ```sh $ man pacman | grep '^[^ ]' PACMAN(8) Pacman Manual PACMAN(8) NAME SYNOPSIS DESCRIPTION OPERATIONS OPTIONS TRANSACTION OP... (more) |

How to overwrite each line of STDOUT with the next one? I wrote a filter program to overwrite each line with the next one. ```sh $ cat /usr/local/bin/ovr #!/bin/sh sed '2,$s/^/\x1B[1A\x1B[K/'; ``` Here's the behavior: ```sh $ echo | ovr $ echo 'foo' | ovr foo $ echo -e 'foo\nbar' | ovr bar $ echo -e 'foo\nbar\nbaz' | ovr baz $ ech...

Yep. I hoped there was a way that I didn't find, but it seems the way is brute force. (more) |

How to see all header fields of an email in mutt? Neomutt (and probably Mutt too, but I didn't try) seems to be hiding header fields from email, such as the Message-ID field, and fields that are added by SMTP servers when they receive the message. How can one ask it to show the entire mail source, as if one was reading the file itself? In othe... (more) |

Who creates subdirs under `/run`? A system daemon needs to create several files under `/run/program-name/` (and possibly other subdirs of that). They are the PID file, and at least one Unix socket file (but maybe more). The FHS specifies that those files go there, under a `/run` subdir: . (In some Unix systems, it would still be `... (more) |
