Didn’t know about auto populating search queries, abbreviations, string scripting, and using private mode.

    I wish that string command and also their math command were just general-purpose utilities pre-installed on all systems.

    Tried to script something with sed the other day and was so confused why my regexes weren’t matching, until we realized you need to pass --regexp-extended to get modern-day regex.

    And then I later tried to calculate an average, which bc decided to round down, because it was presumably doing integer math. I actually ended up running python -c "print($total / $count)", because I could not be arsed to work out, if there was some flag to make bc work properly.

    I’m fine with these tools continuing to exist for legacy purposes, but I would like a modern replacement just about now.

      string split/collect and similar can’t work unless its a builtin. The set foo ( ...... | string ... ) pattern couldn’t work if string was an external binary.

    Scrubbing through the video, this hurts my soul

    echo $(echo $STRING | sed 's/World/Bash/')

    For variables bash has PE forms:

    echo ${STRING/World/Bash}

    I miss these too much when I try Fish.

        Nothings bad about it. I don’t think it’s strictly better or worse. Just

        • I’m used to it
        • The comparison in the video was just disingenuous.

          I haven’t watched the video, but maybe it wasn’t in bad faith, but the author didn’t know better. bash can be arcane at times, like when I open my old scripts I often have no clue what exactly is going on without comments. Substring removal comes to mind.

    It’s perfect for daily interactive use, but terrible for scripting. I write almost all my scripts in bash, the only exceptions being convenience scripts for fish itself.

      Same, but I don’t think it was ever intended differently; I mean the word interactive is literally in the name. If you want portable scripts, use bash. For simple helpers, quickly define a function. If you feel your script becomes too long, use Python.

        Agree, although I’ve recently replaced the python usecase with Go. Almost as easy to write, but much faster and safer.

            Well, it’s statically typed, and it’s memory safe. (There can be some race conditions during concurrent execution, but that’s not relevant for simple scripts.)

          Oh yeah, I never used Python myself and did some very simple (but IMHO too much hassle in bash) Go stuff some time ago. It’s a really good language for that, and if you can’t build on the target, the binary is statically linked anyways.

    I had to switch from fish to bash because one command to install S.T.A.L.K.E.R. - G.A.M.M.A only works in bash. I have no further details on why 🤷
