@#56802 It works because `ls` defaults to `-1` behavior when the output is not a terminal. You can pass `-1` explicitly if you like; it won't hurt.
This is also typical behavior of many \*nix commands that produce column-oriented output when run from a terminal: if run in a context where standard ... (more) |

A: How to get number of files in directory There are several ways that I can think of, depending on how correct you need the answer to be, particularly in exotic situations, and exactly what you want to count. If you know that you don't have any exotic file names in the directory, then a relatively trivial `ls -A | wc -l` will probably do ... (more) |

This might sound like nitpicking, but it's actually not. *Which "system clipboard" are you referring to?* For example, on Linux there's X11's two separate copy buffers and on the console something like GPM's copy functionality; Wayland probably offers something similar; and other \*nixes may do thing...

It's not a daemon, but I suspect most Linux wireless network UIs these days are simply front-ends to Network Manager, in which case perhaps something like `nmcli device wifi list --rescan` and `nmcli device wifi connect ...` might prove useful. See nmcli(1). (more) |

The domain name `mydomain.com` actually belongs to someone, so it's a poor choice for anonymization. RFC 2606 specifically reserves some easily-recognizable domain names, including `example.com`, for use for examples and documentation; those should be preferred. (There's also, for example, `home.arpa... (more) |

VPN tunnel for outgoing connections but still allowing incoming bidirectional connections, using Wireguard or OpenVPN on Linux For a particular use case, I need to be able to set up a Linux host (specifically Debian) to use a VPN tunnel for routing outgoing connections, but still allow incoming connections outside of that VPN tunnel and for the traffic relating to those to be routed outside of the VPN. More concretely, it... (more) |

A: Why is libvkd3d1 not upgrading on my system? (lubuntu 20.04 LTS) In Debian derivatives (of which Ubuntu is one), and more generally those distributions that use the Debian `apt` package manager tool suite, for packages to be "kept back" during an upgrade means that upgrading those packages would require some change that the requested type of upgrade is prevented f...

A: A shell script that can run under different shells I'm not familiar with zsh, but it seems to me that your problem here is that the syntax for `for` loops is different in bash and zsh, which throws bash off as it tries to interpret your script, finds a keyword it knows but the rest of the statement doesn't match what it expects. The solution would... (more) |

A: Should we merge with Power Users? I'm posting the same answer on both sites, because the questions are basically the same.

I don't have any OS X system to check on, but it [looks like](https://docs.brew.sh/Manpage) `brew leaves` will "List installed formulae that are not dependencies of another installed formula" whereas `brew list` will "List all installed formulae and casks". I'm not sure if the exclusion of casks (app... (more) |

@#8046 I wouldn't rule it out without at least checking. The fact that you're getting compilation errors that point toward files from `readline` at the very least strongly suggests that there's an issue there; it doesn't guarantee that that's the problem (some types of errors in the source code can m...

I get the feeling that this relates to readline, perhaps GNU readline, more so than Ruby, really. I suggest to check the installation documentation for mentions of readline version requirements, then look in your /usr/local/opt/readline to see if you can determine what version is actually on your sys...

I don't think that applies, at least not directly. This looks to me to be related to readline; that Github issue is for building with an OpenSSL version that hasn't been updated since 2019 (so almost two years now). (more) |

@#53919 `showkey` on Debian Bullseye (showing its version as `(console-tools) 0.2.3`) has three modes; `--scancodes`, `--keycodes` (default) and `--keymap`. I'm not sure what you're running, but judging by the man page, it's been like that for a long time. (more) |

At least when I try (using `showkey`), it seems that the key down and key release events are very much distinct. I haven't tried using it as a modifier key, though; I already use that key for other purposes which would be incompatible with such use. (more) |

A: How can you create a separate home partition using LVM? I don't use Fedora myself, but from the documentation, it looks like it doesn't use LVM unless you explicitly set that up during installation, but rather Btrfs by default. How your system is actually set up could however very well depend on what the defaults were for the distribution version you init... (more) |

This works fine. I inverted the logic, though, to avoid having to put pretty much the entire main body of the loop inside an `if` statement, adding `test -z "${processed[$1]}" || { shift; continue; }` right near the top of the loop.

A: Make Less use a normal view instead of hexdump view As I noted in a comment thread, I don't get the same behavior as you do (nor do I recall ever seeing it on any system), which points toward something about your setup.

That's not what it does to me; with less 551, I get the expected semi-binary view rather than a hexdump-style view.

In a bash shell script, how to filter the command line argument list to unique entries only, for processing each? I have a handful of shell scripts that accept any number of command line arguments, then do some relatively expensive processing based on each command line argument in turn. The general format for these goes along the lines of #!/bin/bash # preliminary set-up goes here # main loo... (more) |

What other OSes sometimes call a "RAM disk" or a "RAM drive" is called a ramfs or RAM file system in Linux. Assuming that support is available in the running kernel, `sudo mount -t ramfs none /some/mountpoint` gives you one. (The `none` is just an artefact of how ramfs in particular works. The `mount...
