Questions[hidden-files](ubuntu)

Something I feel I ought to know for sure: if I ls <something>, will rm <something> remove exactly the same files that ls displayed? Are there any circumstances where rm could remove files that ls did not show? (This is in the 18.04 bash)

Edit: thank you to everyone who answered. I think the full answer is a combination of all the answers, so I have accepted the most up-voted answer as "the answer".

Unexpected things I have learned along the way:

• ls is not as straightforward as you might think in its handling of its arguments
• In a simple un-fiddled-with installation of Ubuntu, .bashrc aliases ls
• Don't name your files beginning with a dash as they can look like command arguments, and naming one -r is asking for it!

I have a folder where I transfer home videos from a camcorder to. I find two files in this folder that are not videos...

1. .fuse_hidden0000002c00000001
2. .fuse_hidden0000002600000002

What are these files, and can they be safely deleted?

I feel stupid asking, but I can't seem to find the answer to this anywhere. I'm trying to follow these instructions to edit my bash prompt, but there is no .bashrc in either my user directory (~/.bashrc), or in my home directory, or in the main file system directory.

There is no .bashrc in /etc/ (there is a bash.bashrc, however).

Do I create a .bashrc file in my user or home directory? Is there a better, more recent set of instructions for modifying the bash prompt?

My open file dialog is defaulting to showing hidden files, I have to press Ctrl-H to get to the files I want, but this is not saved across instances of the dialog.

I can't find a settings panel to change this behaviour, including Nautilus preferences, nor a key in the configuration editor. Is there a way to have the open file dialog default to not show hidden files?

The OCD in me wants directories I do not like the name of to be hidden since I do not interact with them directly.

How can I hide directories without using the dot notation?
