A: Why is Pause/Break key is immediately released? Can that be fixed? From Wikipedia: Break key: > The Pause key is different from all other keys in that it sends no scancodes at all on release in PS/2 modes 1 or 2, so it is impossible to determine whether this key is being held down with older devices. In PS/2 mode 3 or USB HID mode, there is a release scancode, so... (more) |

@#8049 Since `showkey` only prints scan codes, it shouldn't matter if the key is made a modifier or not. It's interesting that you cannot reproduce it. I tried it on a spare old computer and it was the same behavior. (more) |

Why is Pause/Break key is immediately released? Can that be fixed? Since the Pause key is useless, I tried to map it to a modifier key. What is straightforward for other keys turned out not to work fine for Pause. By inspecting the output of `xev -event keyboard | grep -E '^Key|state'` for holding Pause and then pressing s, ``` KeyPress event, serial 28, synt... (more) |

@#8049 Thanks, indeed the problem was a different environment variable: `LESSOPEN=|lesspipe %s`. So either deleting that variable or using `-L` solves the problem. Would you like to write an answer? (more) |

A: In a bash shell script, how to filter the command line argument list to unique entries only, for processing each? Bash Here Bash's associative arrays come handy. The idea is to put every argument as a key in a separate array, and then only process arguments that are not keys to that array. ```bash #!/bin/bash declare -A processed #Declare that "processed" is an associative array for e in "$@"; do #...

Point 2 is moot: You can put the Sed script in a file and then the shell doesn't get in your way, all quotes are literal. Can you clarify point 1? Sed does allow multi-line scripts and can even do multi-line operations. (more) |

I routinely use MPV for that. mpv --profile=low-latency --untimed av://v4l2:/dev/video0 You may need to try other devices, as listed by `ls /dev/video`.

How would unatended-upgrades package figure out that you, as a person, has access to root account?

What does `emerge --update --newuse --deep @world` have to do with package removal? In Debian-based distributions, one can update the system with `apt upgrade` and cleanup unused dependencies with `apt autoremove`. Period. On Gentoo that is apparently not as straightforward.

The question describes that the GTK theme changes. This may be caused by the GNOME desktop environment. If you switch to a non-GNOME environment (no need to uninstall it, rather just don't start it), you might narrow down whether GNOME is to blame by looking at programs that use GTK, such as Firefox....

Great answer. I'm just wondering about the necessity of editing the modules files (see, for example, [Modules – Debian Wiki](https://wiki.debian.org/Modules#Automatic_loading_of_modules)).

If it contains a non-line, it is not a text file.

I don't really ask for a Platonic category of file, but for the POSIX category. Most text-processing utilities (sed, grep, awk, ...) assume text files in the POSIX specification. To keep my applications portable, I try to conform to POSIX. But then there are many users/editors that, for example, don'... (more) |

Indeed, I had only read `man 1p file`. To be honest I don't see how the information you bring explains the matter. Note that none of the files are reported as UTF-8, but instead the first three as "ASCII", the next two as "non-ISO extended-ASCII" and the last as simply "data". An important question: ... (more) |

@celtschk Well, `file` is [POSIX specified](https://pubs.opengroup.org/onlinepubs/9699919799/utilities/file.html), so I would suppose it conformed to POSIX idea of what a text-file is. (more) |

@Moshi But then any kind of file would be a text-file, since you could say it contained zero lines. Even a file with a NUL would be a text-file. Instead, I interpret that if the file contains non-lines, then it is not a text-file. In that sense, an empty text file would be the only case for which "ze... (more) |

@Moshi True, I said 0x80 was straightforwardly invalid but it is not. Still, it cannot be the first byte of a valid character. It forcefully follows that neither file 4 nor file 5 are newline terminated or that they have an invalid character. File 3 is also not newline terminated (even in ASCII encod... (more) |
