Hello, I yet again come, hat in hand, for assistance from those wiser in the ways of the Linux. I’m having a bit of an issue downloading Jellyfin on my ElementaryOS laptop. I’ve tried all the guide on the first few pages of ddg only to receive errors after entering the comman “ sudo apt-get update “. I get ERR:3 https//repo.jellyfin.org/debian circle Release 404 Not found.

If someone can point me the way I’d be most appreciative

    You can do some wild shit with pipes:

    • head -10 /var/log/syslog - Look at the first ten lines of one of your log files, with timestamps on the front
    • cat /var/log/syslog | cut -d' ' -f1 - Splits the lines by a space delimiter (the -d' ' part), and grabs the first “field” (the one with the timestamp, using -f1)
    • cat /var/log/syslog | cut -d' ' -f1 | cut -dT -f1 - Splits the timestamp at the “T”, and leaves only the date
    • cat /var/log/syslog | cut -d' ' -f1 | cut -dT -f1 | sort | uniq -c - Gives you a count of each date
    • grep systemd /var/log/syslog | cut -d' ' -f1 | cut -dT -f1 | sort | uniq -c - For only the lines with ‘systemd’ on it, gives you a count of each date

    The standard GNU toolkit has a ton of utilities like that for doing stuff with text files.

      I find it unbelievably cool that the guys who came up with this got it so right the first time, that its still incredibly powerful today.

      At work whenever we need to build little command line tools, my team is always vexxed by my guideline to have the meat+potatoes in a script that reads well-formatted data off stdin , and outputs well formatted-data to stout. They always wanna have some stupid interactive prompts and saving to files baked right in.

      This is exactly why. You wanna save to a file?? > file

      You want to read from a file? cat |

      You want to save to a file but swap commas for colons? Sed.

      You get so much FOR FREE w/ the GNU toolkit, even for what you build yourself, by thinking in streams.
