How to check spam headers of EML file from command line? If I have an email in EML format, how can I determine its spam status from the terminal? My mail provider appears to insert a `X-Acme-Spam-Status` header. It looks like ``` X-Acme-Spam-Status: v=1; e=base64; a=aes-256-gcm; d=...` ``` The part in `d` is a 400 char string that looks like base... (more) |

Albert with compositor surrounded by ghost of other windows On Arch Linux, I installed albert (from AUR) and picom as the compositor. I am using i3 as the window manager. When I bring up the albert window, it is surrounded by the ghost of a window in the background. So for example if I open a browser and terminal in the tabbed layout, with the browser focu... (more) |

A: How to RTFM well to get a CLI command The existing answer is good, but I'll add a short version. 1. `man FOO` is the most reliable way. A large majority of programs have a man page, and a large majority of man pages cover all aspects of the program (assuming you have the patience to read it). By default, most Linuxes will open t...

A: Looking for a way to sync dotfile content between different machines without introducing security issues Git is a very good way to sync dotfiles. There are other sync methods, but git also gives you version control, which is the other crucial part of the dotfile approach. Dealing with secrets in git is not unique to dotfiles. All sorts of projects encounter this issue. For example, a webapp may need ... (more) |

Is it safe to completely take over ~/.config/systemd/user? `/.config/systemd/user` intended purely for units created and managed by the user manually, or are there any automated processes that expect to control it? For example, do packages or programs ever create or manage their own files in this path, without the user explicitly requesting it? Is it s... (more) |

A: Modern and practical way to schedule tasks on a Linux machine that is not always on Historically, cron was the main way to schedule tasks on Linux. Briefly, there will be some file like `/etc/crontab` which will contain one line for each task. The line starts with a schedule string and a shell style command. The schedule string specifies on which minutes, hours, days and months ... (more) |

A: Modern and practical way to schedule tasks on a Linux machine that is not always on The standard way to schedule tasks in most Linux systems nowadays is to use systemd timers. This requires writing a systemd timer config file, which has syntax similar to INI. This is summarized in https://wiki.archlinux.org/title/Systemd/Timers and covered in detail in systemd docs. The timers... (more) |

In i3wm when moving windows, how do I also switch to the workspace if it's active? Let's say I have workspaces 1, 2, 3 on screen A and 4, 5 on screen B. Currently workspaces 1 and 4 are active. With my current config, moving a window to another workspace never activates it. How can I make it activate the workspace if it's active (from 1 to 4) but not otherwise (from 1 to 5)? (more) |

Name or path? Kind of a big difference in this context :)
For names I don't think it really matters, but also I don't see much reason for a de jure limit (as opposed de facto limits imposed by implementation, which come and go without impacting the official standard).
For paths, it can be very ... (more) |

Actually, I think a corollary of my question is if you restrict filenames, then what happens when some program you install does try to create one? (granted, in Linux most packages do not have junk in filenames - I doubt if any do)
So you would want to leave a backdoor so that the *system* can crea... (more) |

I also had a question about this. I think the argument is
> You can't just read the source code of all your programs and figure out which ones will create files.
Which is theoretically true. In practice, the vast majority probably use a handful of system API calls for file creation.
However,... (more) |

@#8049 Closing the question for this feels unfriendly to me.

A: shell and shell-scripting tags: duplicates? My assumption has been that `shell-scripting` is for scripts only, not interactive usage. Whereas `shell` is everything else, like interactive usage.
