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 caution to anyone adapting this for their own use: don't forget t... (more) |

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. Apparently in response to the question about your /.bashrc, you showed that you run this from a freshly started shell (`bash --norc`)... (more) |

That's not what it does to me; with less 551, I get the expected semi-binary view rather than a hexdump-style view.
A few things of note:
That new `bash` session might not itself read the shell initialization files, but it's going to inherit the environment from the spawning shell. That could i... (more) |

| Question | — |
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) |

More generally, point 2 is about the shell, not about sed, so any other tool that takes a similar expression as a command line argument would require similar quoting (or other handling) of that expression. It seems to me that this question simply seeks a way to split a sed expression onto multiple li... (more) |

As an alternative approach, if the system running the flasher program has network access, you can mount a file system over the network and just access the data that way, removing altogether the need to store the file on the flasher system. (Though consider how the flashing process will deal with, for... (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...

@#53919 The `mpv` man page has several more options one can try; those are just the ones that happened to do the trick for me. Look at the "low latency playback" section. In particular, the man page notes that `--untimed` can break streams that have audio. (Which, aside from the fact that I'm not rea... (more) |

I ended up having to add `--profile=low-latency --untimed` to avoid a few-seconds latency in playback due apparently to buffering, but this works nicely after I added my user account to the `video` group which owns the /dev/video\* device nodes. (more) |

@#36356 Right now I don't have any specific software in mind other than Microsoft Teams running inside a Windows VM which I'm stuck with for work. It may well turn out to be various web applications running inside a browser instance, for one thing. Also, I would rather have *one* solution which works... (more) |

With a V4L2-compatible webcam, how to see its video feed for the purpose of adjusting aiming? I have ordered (but am still waiting for it to arrive) a USB-connected webcam that is supposed to be V4L2 compatible. Once it arrives, I'm obviously going to want to mount it such that it provides a reasonable picture with minimal ongoing adjustments. I imagine that the easiest way to do so is to ... (more) |

A: How to detect if a Linux Docker host has had unwelcome guests? You can't expect an attacker to abide by any particular rulebook. In fact, if they did, then the defenders' job would be so much easier. That's why attackers don't do it. Remember the adage: a defender has to defend against every possible attack everywhere, but an attacker only has to find one ... (more) |

This answer would be much more useful if, instead of just stating the package name needed for one particular printer, it were to describe how you arrived at the conclusion that this was the correct course of action.

A: How to give password in shell script? > That's my bash script. Actually, no, it isn't. Assuming for a second that the shebang line is `#!/bin/sh` (not `#!bin/sh` as you have it in the question), it's a sh shell script, not a bash shell script.

I don't think this is on topic for Linux Systems Codidact, as there is nothing in it that is clearly specific to any kind of Unix; it's a question about LibreOffice, which runs on many platforms, not all of them Unix-like. It would probably be a better fit on Power Users. See https://linux.codidact.c... (more) |

The MySQL `root` user has nothing to do with the system `root` user; the two user namespaces are separate. Also, best practice is to avoid running processes, especially complicated programs, as uid root if possible. Is there any particular reason why you suggest using `sudo` when invoking `mysql`?

@#54146 See my edit.

@#53922 If you don't even have `modprobe` installed, then your system is bare enough that there's probably a good number of other things missing which will cause headaches down the road; `modprobe` is provided by `kmod` which has priority `important`, same as `apt` which provides `apt-get`.
