I've just started my Linux journey earlier this year. As a goal to learn how to self-host applications and services that will allow me to take back some control of my data. Immich instead of Google Photos, for example.
I have a local server running Unraid and 22 docker containers now. And then a VPS (Ubuntu 20.04 LTS) running two apps. I've learned a ton but one thing I can't seem to wrap my brain around is navigation through the file structure using only terminal. My crutch has been to open a SFTP session in Cyberduck to the same device I'm SSH'd to and try to figure things out that way. I know enough to change directories, make directories, using Tree to show the file structure at different levels of depth. But I feel like I'm missing some efficient way to find my way to files and folders I need to get to. Or are y'all just memorizing it and know where everything is by now?
I come from a Windows background and even then I sometimes catch myself checking via explorer where a directory is instead of using CMD or PowerShell to find it.
I'd love to hear any tips or tricks!
EDIT: I've been using Termius because they have a great Android client, but I wasn't about to pay $5/mo for sync. Especially to sync to someone else's cloud. Which led me to Tabby, which I understand has quite a large footprint resource-wise. But I guess I either don't know enough yet to be mad about it or it hasn't impacted any of my systems negatively yet. No Android client though, but you can bring your own sync solution and it has a handy little shortcut to SFTP to the current directory you're in. Between that and stuff like ranger, it's made it so much easier to learn my way around!
Something I haven't seen mentioned here is Ctrl + R on the command line to quick-search history. You start typing/backspacing and it shows the most recent matching history entry. Press Ctrl + R or Ctrl + Shift + R to navigate up and down through matching entries. Press Enter to pick an entry, Ctrl + C to cancel.
Also, if OP is new, they may not yet be aware of aliases and functions. Generally you'd out those in a ~/.bashrc file that gets automatically executed when a terminal starts. They'll allow you to save a more complex command as a really simple one. And particularly can be useful when things you want to run are in unusual directories. Eg, maybe you have a git repo somewhere that contains some project you spend most of your time on, so you could have an alias that just cd's you to it's directory. Git also has its own way of doing aliases and that's really nifty for the more complicated git commands (or the more commonly used, like st for status).
I saw that mentioned in another comment and I've been testing it out while I try to get Cryptpad installed on my VPS and its very nice!
You can also make this the default behaviour as you start typing a command.
Create ~/.inputrc and add these lines:
