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... (more) |

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... (more) |

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 ... (more) |

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... (more) |

@#53054 Done. However, please keep in mind that if an edit would invalidate existing answers, it is generally better to post a new question incorporating what you have learned and highlighting how the new is different, than to edit an original question in such a way that existing answers no longer ap...

A: How to extract string from file, run filter, and replace in file with new value? > - iterate through all `chapter-.xhtml` files in a directory Assuming bash, and assuming that at least one such file exists in the current directory (otherwise adjust the path and/or `shopt -s nullglob`), you can use a simple `for` loop to do this. for filename in chapter-.xhtml; do ...

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... (more) |

@#61308 I would honestly not consider it a "small detail" whether you are interested in answers for, say, FreeBSD, Windows Subsystem for Linux, Mac OS X, Linux, or Illumos, to name just a few possibilities; especially for a question where answers are likely to touch on deep aspects of the workings of...

@#65946 That's odd; I tried my example in a Trixie VM and got the same results that I showed in my answer. Well, whatever works for you. Hopefully this will be useful for someone else. (more) |

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... (more) |

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... (more) |

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?

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 ... (more) |

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. (more) |

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 ... (more) |

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.

I believe it can have, at least in some circumstances. With the GNU coreutils 8.32 `ls` and GNU findutils 4.8.0 `find` on Debian 11/Bullseye, observe:
$ cd $(mktemp -d)
$ touch abc$'\n'def
$ /bin/ls -N
abc?def
$ /bin/ls
'abc'$'\n''def'

A: Adding Python 3.11 to `$PATH` 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... (more) |
