I've never been a huge fan of the plethora of graphical file managers available for Linux. I agree with a friend that "none of them get it right." So I've tried many file managers over the years, but I mostly manage my files from the command line.
So your tip for today is to install vifm (it's available in the regular repos for Fedora, Ubuntu, and Debian). It's a file manager I've looked in on about once a year for the past five or six years, and I think it's finally got to the point where I'm going to start using it. I love the dual pane layout, and of course the Vim integration. I'd suggest you fire it up, notice that
<Tab> gets you between the panes,
/searchterm finds file names,
k move you up and down ...
Now quit (I know you're having fun playing, but do this first). Use your favourite editor to edit ~/.config/vifm/vifmrc (that's where it was on my system: it may be ~/.vifmrc on yours - if neither, I'm afraid you'll have to look at the docs). There's only one reason we're editing this file: the very first uncommented line in the file says:
This is clearly wrong. Change it:
(Obviously you shouldn't do this if you're not using NeoVim ... you should be.) Now you can play. Try renaming a file by typing
:rename when the file is under the cursor. Move to another directory in one of the panes. Use
dd on a file, hit
p to paste the deleted file. You can of course also do
yy to yank a file and paste a copy into the other directory.
Special bonus extra (I haven't tried this, but I'm glad it's available): if you really like vifm, you can use it as the file picker inside NeoVim to replace netrw and/or Nerdtree. ( https://github.com/vifm/neovim-vifm )
