(Of course, it occurs to me that even if setting up a full `chroot` environment weren't necessary, I would *at least* have to mount the new root partition in the live system so as to have access to *its* `/etc/fstab` (rather than that of the live boot)...) (more) |

I'm pretty sure the system is using UEFI and GPT, and the bootloader should be GRUB2. I had hoped that I would *only* need to edit `/etc/fstab` or similar files, but it's good to see that there is at least a viable approach to this.
To be clear: I infer that the point of mounting a temporary setup... (more) |

Thanks for the comprehensive overview. It makes perfect sense to me.
I went in to this thinking that I wouldn't want to upgrade the entire OS more than every 4 or 5 years anyway, but it feels like I pay a heavy price in terms of software versions being much further out of date than I expected, and... (more) |

| Question | — |
Why/how can distro support lifetimes exceed the lifetime of their dependencies (such as Python)? Motivating example: my Mint 20.3 distribution offers long-term support until April 2025, which matches the "standard support" offered for the upstream Ubuntu (20.04 "Jammy Jellyfish"). However, the system-provided Python version is 3.8, which reaches the end of security support this October, half a y... (more) |

A: What is cat abuse/useless use of cat? Overview A "useless use" or "abuse" of `cat` occurs when a Unix pipeline (sequence of commands that feed into each other, using the shell `|` or "pipe" operator) includes a call to `cat` that is unnecessary for solving the problem. Such pipelines are naturally less efficient (since the OS has t... (more) |

Group and users seem to disagree about whether the users are in the group On my current setup (running Linux Mint 20.3 Cinnamon), I have an administrative user and several ordinary users. I intend for all of these users to be in the same group, which happens to have the same name as the admin user name. (After doing the basic guided setup and looking up some tutorials, I u... (more) |

A: Is there a way to automatically normalize paths when extracting RARs? If all else fails, you could create a wrapper shell function to check the output of `unrar l` (probably by piping to `wc -l`) and proceed accordingly. (more) |

My actual use case involves mostly large binary files. I have a vague recollection of using Unison on Windows many years ago; I think I must have assumed that it only existed to replace `rsync`. But now I've seen that Unison is used on Linux for good reason, and also that `rsync` builds exist for Win... (more) |

This makes it feel like my original question is "a typo" by the reasoning I would normally apply - but I sense that there's the working of a more general principle here that could be written up in a better designed Q&A.
I also notice, for example, that `sudo whoami && whoami` gives my own username... (more) |

How does the root user locate executables? A little while ago I was helping someone with running Python in a virtual environment, as root, for some specific purpose. I determined easily enough that this requires explicitly specifying the path to the virtual environment's Python executable (which to some extent defeats the purpose of the "virt... (more) |

I realize now that I had originally been thinking in terms of `xargs` because of a previous wrapper I made, to identify files to tally with `wc` (which needs a single invocation with all the arguments, in order to get the sum, of course). I went back and fixed that to use `-print0` / `-0` at least. (more) |
— | 8 months ago |
| Comment | Post #289794 |
This is brilliant; I had a feeling (after realizing the issue in my first attempt at the question) that `xargs` was complicating things given that `find` has a `-exec` argument. This really allowed me to get my head around the needed quoting schemes, too, and explains general best practices (I am not... (more) |

Higher-order functions in Bash? Say I have some Bash function `my-func`, that expects a filename and does some processing on the corresponding file.

(It looks like you've already considered this, but.)

How can I get a Flatpak dependency graph? `flatpak uninstall --unused` currently tells me that there is `Nothing unused to uninstall`.

Is there any way I can get Flatpak to show me a gr... (more) |

Based on the answer that "worked for" you, it seems that I did have the right "bookmarks" in mind. You can create these in other ways, for example by using ctrl-D in Nemo while a window is focused. (There is an [outstanding bug report](https://github.com/linuxmint/nemo/issues/2921) for Nemo, whereby ... (more) |

... Because they persist between uses of the dialog? And because, at least in Nemo, I can see bookmarks in the left-hand panel of the file browser windows? If you had a different kind of bookmark in mind, then I don't understand what it is and the question would probably be better of with an explicit... (more) |

It's not clear to me how GtkFileChooserDialog relates to the question, since "bookmarked folders" would seem to be an OS-level (or at least window-manager-level) feature, not something specific to an API call for a GUI library. Do you mean that you used a program that generates a file-save or file-lo... (more) |

It's mainly an aesthetic preference. The desktop is the main place I *put things* for ready access, and I want to be able to *see* whatever ends up there and deal with it according to my preference, without having to hop over to a terminal.
