Having been in this situation (the only binary I could use was
bash, althoughcdwas a bash builtin for me),echo *is your friend. Even better is something like this:get_path_type() { local item item="$1" [[ -z "$item" ]] && { echo 'wrong arg count passed to get_path_type'; return 1; } if [[ -d "$item" ]]; then echo 'dir' elif [[ -f "$item" ]]; then echo 'file' elif [[ -h "$item" ]]; then echo 'link' # not accurate, but symlink is too long else echo '????' fi } print_path_listing() { local path path_type path="$1" [[ -z "$path" ]] && { echo 'wrong arg count passed to print_path_listing'; return 1; } path_type="$(get_path_type "$path")" printf '%s\t%s\n' "$path_type" "$path" } ls() { local path paths item symlink_regex paths=("$@") if ((${#paths[@]} == 0)); then paths=("$(pwd)") fi shopt -s dotglob for path in "${paths[@]}"; do if [[ -d "$path" ]]; then printf '%s\n' "$path" for item in "$path"/*; do print_path_listing "$item" done elif [[ -e "$path" ]]; then print_path_listing "$path" printf '\n' fi done }This is recreated from memory and will likely have several nasty bugs. I also wrote it and quickly tested it entirely on my phone which was a bit painful. It should be pure bash, so it’ll work in this type of situation.
EDIT: I’m bored and sleep deprived and wanted to do something, hence this nonsense. I’ve taken the joke entirely too seriously.
was a bit painful
Well that’s an understatement
My pain tolerance for shitty input methods has been permanently warped after experiencing psychic damage from using Teamviewer to connect to a system over a very flaky HughesNet satellite link. I was working for a vendor that supplied a hardware networking box to a stupid retail company that sells food and shit. I just wanted to ssh to our boxen on a specific network so I could troubleshoot something, but the only way I could get to it was via putty installed on an ancient Windows XP desktop on the same network as our box that could only be accessed with Teamviewer. My favorite part of that was that the locale or something was fucked up, so my qwerty keyboard inputs were, like, fucking transformed into azerty somehow?? The Windows desktop was locked down and monitored to a tremendous degree, so I couldn’t change anything. The resolution was terrible, the latency was over a second, and half of my keyboard inputs turned into gibberish on the other side.
Oh, and I was onsite at that same company’s HQ doing a sales engineering call while I was trying to figure out what was wrong. I spent 5 days sitting in spare offices with shitty chairs, away from my family, living that fucking nightmare before I finally figured out what was wrong. God damn, what a fucking mess that was. For anyone reading this, NEVER WORK FOR GROCERY/DRUG STORE IT. They are worse than fucking banks in some ways. Fuck.
EDIT: also, I asked ‘why Teamviewer’ and the answer was always shrugs. This was before the big TeamViewer security incidents, so maybe they thought it was more secure? Like, at least they didn’t expose RDP on the internet…
Yeah, suddenly coding on a phone doesn’t seem so bad
It very definitely was 😅 The way that company used the satellite network was cool, don’t get me wrong. They would use it to push content out to all their stores with multicast which was really efficient with bandwidth. I loved it for that, but I hated interacting with it over unicast in any way, shape, or form. Horses for courses, as they say.
… but
cdis a built-in-1 accuracy point ( ◞ ﹏ ◟)
linux 4.5-rc5 had efivarfs fixed to prevent “rm -rf /” bricking uefi motherboards – so maybe someone can try it out? :]
It would be pretty useless if cd was a child process that changed its own directory, only to return to bash and be back where you started.
Reminds me this great story from a different era:
THANKS!!! I have it bookmarked forever now!
I lost access to it. Thank you for bringing it back to me! Yay!..
I got reminded of it last week after years. What are the chances it came up again. 😁
Hmmm command not found, let me just try the same command a couple more times, this time it will work right?
In IT teaching users to actually read and understand errors is always an uphill battle.
Tbh I’d try it multiple times too, just because the concept of cd not being there is horrifying and cannot possibly be the case
Very true, I would do the same and feel my stomach drop farther each time.
Never dealt with an intermittent failure or race condition, eh?
Where is the Windows ‘help’ button, did you try that?
No problem, just tab complete your way around the filesystem.

I am immune to /dev/sda for I only have nvme
I love the nvme partition naming. Looking at you nvme1n1p3
deleted by creator
Eh? Idk if I agree. My original comment was entirely a joke based on the fact that the literal argument of=/dev/sda has no affect on my system but to address your actual point. I personally don’t find nvme naming any more confusing than SCSI. /dev/nvme0n1 is only one char away from /dev/nvme1n1 just like sda vs sdb. Additionally if you understand how the kernel comes up with those names they make a lot of sense. The first number is the controller, the second is the namespace or drive attached to that controller, the 3rd if present is the partition on the given drive. It is entirely possible to have a controller with more than one namespace. That aside aside…I think there is a genuine benefit to be argued for having USB drives, which are SCSI and fall into sdX naming separate from system drives as I dd far more USB media than system media.
I realized I was long overdue for a hardware refresh when I learned that nvme drives are /dev/nvme and not /dev/sd[x] and I realized every single computer I interacted with was pre-nvme
An unintended benefit of using Qubes is that everything is a virtual machine and physical disks have to be manually attached to a vm before doing operations like
dd. I haven’t had to worry about accidentally nuking my main partition for a while.Huh, yeah I suppose that’s true. Qubes is an interesting project but I’m not sure it’s for me. I selectively isolate apps I worry about using containers, I actually should give flatpak a try as it basically does that for me but I haven’t seriously tried it yet.
I see girls last tour, I upvote.
echo $PATHAnd
aliasto be sure.bash: echo: command not foundbash: alias: command not foundechoandaliasare both shell commands. If the shell is running (which it obviously still is), those commands should still work, as it does not involve reading data from disk, but from memory.Edit: I just noticed the picture said
cdwas not found, which is also a shell built-in. So, I don’t know.Just tested it in a container. The original screenshot is wrong:
Why would somebody lie on the internet?

Switch your calculator with a computer. Try again.
Empty
$PATH.This isn’t programming, just someone who sucks at bash.
How else are you going to open your files in nano to do the programming on the prod server?
what’s a nano?
A metric prefix that represents 10e-9 of a unit.
The beginner (and better) version of vim?
sudo dd if=. /rpi3-aarch64-archlinux.img status=progress of=/dev/sd[tab] [tab] [enter]
I remember being so scared the first time I screwed up my
$PATHguix rollback
