Yes :)
If the answer is
> You cannot trigger cron jobs manually. You can only do that in systemd, this is one of the things systemd tried to "fix" vs. cron.
That is acceptable, I just don't know for sure if it is. (more) |

A: How do I migrate my main filesystem to a new drive? Gnome disks can create a disk image, and then restore it to the new one. The new drive has to be same size or larger, although this is obvious. If it is larger, the partition will still be small, but I find it easier to resize it after the fact. It's better if the sector size also matches: http... (more) |

Manually trigger cron jobs Do any of the cron implementations allow you to manually trigger cron jobs (stuff in your crontab) right now, in the exact same manner as they would have when triggered on their usual schedule, except for timing? (more) |

A: Why/how can distro support lifetimes exceed the lifetime of their dependencies (such as Python)? When PSF says Python 3.8 is not supported, they are simply saying they will no longer bother fixing bugs in or adding stuff to that version. It's not like Python 3.8 will start automatically exploding your computer the moment they drop support. They just don't want you to come complain to them if you... (more) |

A: What are non-POSIX shells and what's the point of them? From the average user's perspective: Back in the day when people were figuring out how to do shells, there were as many shell syntaxes as shells. Everyone made up their own little language to go with their shell. Most of them sucked big time. One sucked a bit less, that became bash. The others die... (more) |

How do you generate arbitrary random numbers from /dev/random? Suppose I want to get random numbers from `/dev/random` with basic CLI tools. Is there a way to do it, that's easier to type and read than `python -c 'import random; print(100 + 200random.random())'`? I know how to generate random strings and I could generate a string of digits. But that's not ver... (more) |

A: What is cat abuse/useless use of cat? UUOC is an ancient Unix yarn. I can't find the original essay (I believe from Usenet, where else...) but if memory serves it's either from early 90s or before. `cat` is actually a program for concatenating files. `cat file1 file2 ...` will give you `file1+file2+file3`. Together with `split`, this ... (more) |

A: How do you generate random strings from /dev/random? `/dev/random` is a stream of every possible value. You're supposed to filter it to take the ones you want. This is efficient, although if the values you want are such that only, say, 1% of what comes out of `/dev/random` is acceptable, then it will obviously take 100x longer to generate them. But luc...

How do you generate random strings from /dev/random? Of course every language has some kind of `random` library... But can you generate custom random strings with just basic CLI tools? For example, we have `/dev/random` which provides a stream of random values... But they're random bytes, so a lot of them are non-printable or special characters. If ... (more) |

A: Which Linux system to use? Most Linuxes are small, and I would consider them for experts by default. This is because you won't be able to just Google problems and copy the solution from some blog. You'll have to actually troubleshoot yourself, read manuals, understand the system and discover the fix yourself. Most Linux softwa... (more) |
