Answer A: How to open documentation in qch format in Debian based systems?
A web search turned up the Qt online documentation, which suggests using Qt Assistant to organize and read help files packaged as \.qch files. That looks to be packaged by Debian as assistant-qt6. Alternatively, cppreference-doc-en-qch depends on qttools5-dev-tools which in turn pulls in qt5-assis...

Answer A: Adding mount points to an existing partition that already has one
Yes, bind mounts or possibly rbind mounts is most likely what you want here. You need a rbind mount if you want the contents of file systems mounted below the specified mount point to be accessible in the new location as well; you need a bind mount if you don't want or need that. Given the situati...

Answer A: Do domain-specific how-to's fit well within Q&A?
My immediate reaction would be that yes, it can definitely fit in the general Q&A category. And there is no rule against self-answers to questions. However, please do take a bit of care with how the respective posts are written. Mainly, the question needs to be self-contained, and it should allow ...

Comment Post #291145 You can also put the input file direction first, if that makes the overall command easier for you to parse. So you can write </dev/random fooprog instead of fooprog </dev/random if you want. The observable effect is the same: `fooprog` will execute with its standard input set up t...

Answer A: Find out which process is using a port
Use `netstat -lp`. Typically in such a scenario you will likely be mostly interested in IP sockets, in which case you can also add `-A inet,inet6`. To get numerical port numbers, add `-n` as well. (See the man page for details.) Look at the "local address" field to find the port binding in ques...

Answer A: Can rsync handle moves and renames?
I'm quite certain that rsync is not able to deduce that /path/to/src/foldera/filew on one side of the transfer is identical to /path/to/src/folderc/filew on the other side of the transfer. Therefore, rsync won't be able to handle such a move efficiently. To stock rsync, it will appear as one file ...

Comment Post #290588 This isn't an answer specific to pacman, but if you're using bash, you can use command repetition with a prefix (or suffix). For example: $ ls /root ls: cannot open directory '/root': Permission denied $ sudo !! sudo ls /root [sudo] password for <user>: <list of fi...

Answer A: How to change resolution of virtual terminal?
I think that you have two options. The literal answer would be to pass `video=` to the kernel. For example, you could pass `video=720x400` to run the framebuffer at a 720x400 resolution, assuming that the specified resolution is supported by your hardware. See modedb default video mode support and...

Answer A: Rename multiple files which have a variable suffix
You can use rename for this. Many distributions package it; for example, it's apt-get install rename in Debian. In normal usage, it is used to apply an arbitrary regular expression substitution expression to the name of each file named on the command line, allowing you to do complex renamings rela...

Answer A: How to bypass SSH destination host key fingerprint check?
I'm going to assume that you're using OpenSSH, since that is probably the most common SSH implementation on present-day \nix systems. The easiest is probably to use `ssh-keygen -R` to delete all known host keys for a given host name. So if you have just reprovisioned `vps1.example.com` and it ther...

Comment Post #289799 When all else fails, there's always the brute force way. I don't have abook installed, but based on the man page you linked it doesn't look like it supports an output format that will natively do what you want. However, based *only* on your one example, might this do the trick? `$ abook --mutt-...

Answer A: How to see all header fields of an email in mutt?
When viewing a message, press `h`. To return to the normal view, press `h` again. With typical viewer key bindings, `h` is bound to the `display-toggle-weed` function, which controls whether all headers are displayed or whether headers are "weeded". (Under the hood, it toggles the `$weed` boolean ...

Answer A: Run a command *later*

Comment Post #289442 There might be some edge case where you need to use `sudo` for `ip addr show`, but generally, that's an unprivileged command. So there should be no need for `sudo` in this case.

Answer A: How do I set up my own DNS on my LAN, with delegation of public domains?
What you describe is a typical mixed authoritative/recursive resolver setup. Such a DNS server setup will respond from its own data about zones for which it has explicit configuration, and will perform recursive resolution for any other names on behalf of clients. Exactly how to set it up depends ...

Comment Post #288929 I'm not up to writing an actual answer, and if someone wants to take this and turn it into an answer before I have a chance to then that's fine by me; but actually using the MAC address directly to generate an IPv6 address, as that page seems to do, has been broadly discouraged for a good while.

There are two possible issues that I can see. First, as already brought up in a comment thread, it appears that the `export` command you added in your `.bashrc` is missing a final `"`. This should cause an error message to be printed when starting a shell, making it an easy error to spot. Secon...
