## Config File
|
||||
|
||||
If you don't have a `~/.config/lf/lfrc` file, you can probably find an example in `/usr/share/examples/lf`.
|
||||
|
||||
```bash
|
||||
cp -r /usr/share/examples/lf ~/.config/
|
||||
```
|
||||
|
||||
Go straight to root with two keys.
|
||||
|
||||
```bash
|
||||
map g/ cd /
|
||||
```
|
||||
|
||||
Have lf open a file with the default program when you press 'o', using the program `mimeo`.
|
||||
|
||||
```bash
|
||||
map o &mimeo $f
|
||||
```
|
||||
|
||||
Change that default text editor to look at the extension first.
|
||||
|
||||
```bash
|
||||
cmd open ${{
|
||||
case $(file --mime-type $f -b) in
|
||||
application/x-sc) sc-im $fx;;
|
||||
text/html) w3m $fx;;
|
||||
text/*) $EDITOR $fx;;
|
||||
video/*) nohup mpv $fx --really-quiet >/dev/null &;;
|
||||
*) nohup $OPENER $fx >/dev/null &;;
|
||||
esac
|
||||
}}
|
||||
```
|
||||
|
||||
The idea here is to use the default `$OPENER` for lf, but first check extensions.
|
||||
Note the extra `mpv` commands to leave the video to play, without blocking the terminal.
|
||||
|
||||
### Interesting Options
|
||||
|
||||
You can set the screen ratio with
|
||||
`set ratios 1:2:3`
|
||||
|
||||
That leaves it as a small initial pane, a medium pane, and a large pane for file previews.
|
||||
|
||||
### Rename
|
||||
|
||||
The standard renaming is bad, because you have to re-type the file extension.
|
||||
Use this instead:
|
||||
|
||||
```bash
|
||||
# rename current file without overwrite
|
||||
cmd rename %echo 'name: ' ; read name ; extension="${f##*.}" && newname="$name.$extension"; [ "$f" = "$extension" ] && newname="$name"; [ ! -e "$newname" ] && mv "$f" "$newname" || echo file exists
|
||||
map r push :rename<enter>
|
||||
```
|
||||
|
||||
If you try to rename `image_1.png` with this command, you can type in `cats`, and the result will be `cats.png`.
|
||||
|
||||
## Image Previews
|
||||
|
||||
First, install `ueberzug` (to show images).
|
||||
Then clone the lfrun repo.
|
||||
|
||||
```bash
|
||||
git clone https://github.com/cirala/lfimg.git
|
||||
|
||||
cd lfimg
|
||||
|
||||
sudo make install
|
||||
```

# On server
|
||||
|
||||
Enable remote desktop access.
|
||||
|
||||
```bash
|
||||
sudo apt install vnc4server xfce4 xfce4-goodies
|
||||
```
|
||||
|
||||
Disable the vncserver desktop:
|
||||
|
||||
```bash
|
||||
vncserver -kill :1
|
||||
```
|
||||
|
||||
Replace the config in ~/.vnc/xstartup with:
|
||||
|
||||
`#!/bin/bash`
|
||||
|
||||
`startxfce4 &`
|
||||
|
||||
# Arch
|
||||
|
||||
Install tigervnc, then run it to set a password:
|
||||
|
||||
```bash
|
||||
vncserver
|
||||
```
|
||||
|
||||
You'll get a session number.
|
||||
|
||||
Shut it down with the 'kill' command and the session's number:
|
||||
|
||||
```bash
|
||||
vncserver -kill :1
|
||||
```
|
||||
|
||||
This will forward over port 5900+x where x is the session number. For the first server, that's port 5901.
|
||||
|
||||
# Create a systemd service
|
||||
|
||||
```bash
|
||||
sudo vim /etc/systemd/system/vncserver@:1.service
|
||||
```
|
||||
|
||||
Then enter:
|
||||

||||

|
||||
> Description=Remote desktop service (VNC)
|

|
||||
|
||||
Then enable that service:
|
||||
|
||||
```bash
|
||||
sudo systemctl start vncserver@:1.service
|
||||
```
|
||||
