This is the home of my fetch script! This script gathers info <br />
|
|
about your system and prints it to the terminal next to an image of your choice!

|
#### Sizing the image correctly
|
|
|
|
**NOTE:** For the images to be sized correctly you need to set the `$font_width` variable.
|
|
If you don't know your font width in pixels keep trying values until the image is sized correctly.
|
|
|
|
You can also use the launch flag `--font_width` to set it on the fly.
|
|
|
|
|
|
#### Customizing what info gets displayed
|
|
|
|
At the top of the script there's a function that allows you to customize all of the info that gets displayed.
|
|
|
|
Here's what you can do:
|
|
|
|
- Add new info lines
|
|
- Change the ordering of the info
|
|
- Remove unwanted info lines
|
|
- Use bash syntax to control when info gets displayed
|
|
|
|
See this wiki page that goes more in-depth about it:
|
|
|
|
https://github.com/dylanaraps/fetch/wiki/Customizing-Info
|
|
|
|
|
|
#### Customizing the script using a custom alias
|
|
|
|
If you don't want to edit the script you can customize almost everything using launch flags!
|
|
|
|
Here's what my fetch alias looks like:
|
|
|
|
```sh
|
|
alias fetch2="fetch \
|
|
--block_range 1 8 \
|
|
--line_wrap off \
|
|
--bold off \
|
|
--uptime_shorthand on \
|
|
--gtk_shorthand on \
|
|
--colors 4 1 8 8 8 7 \
|
|
"

## Frequently Asked Questions
|
|
|
|
|
|
#### Why doesn't fetch support my wallpaper setter?
|
|
|
|
It's hard to add support for other wallpaper setters as<br \>
|
|
they don't provide a way of getting the current wallpaper from the cli.
|
|
|
|
If your wallpaper setter **does** provide a way of getting the current wallpaper<br \>
|
|
or you know where it's stored then adding support won't be a problem!<br \>

## Issues and Workarounds
|
|
|
|
|
|
#### fetch: line 1655: /usr/lib/w3m/w3mimgdisplay: No such file or directory
|
|
|
|
|
|
You're getting this error because the script can't find w3mimgdisplay in it's<br \>
|
|
default location. You can fix this by setting the config option `$w3m_img_path`<br \>
|
|
to the correct location of w3mimgdisplay.
|
|
|
|
Other places that `w3mimgdisplay` could located be are:
|
|
|
|
/usr/lib/w3m/w3mimgdisplay
|
|
/usr/libexec/w3m/w3mimgdisplay
|
|
/usr/lib64/w3m/w3mimgdisplay
|
|
/usr/libexec64/w3m/w3mimgdisplay
|
|
|
|
|
|
#### The image is blank and won't show up.
|
|
|
|
|
|
If the images display in `ranger` and `w3m` then it's an issue with my script and not<br \>
|
|
your terminal emulator.
|
|
|
|
Some terminal emulators don't support viewing images with w3m. You can either disable<br \>
|
|
images with `--image off` at launch or `image=off` inside the script.
|
|
|
|
|
|
#### The image is rendering with black lines in Urxvt while using an xft font.
|
|
|
|
This is an issue with w3mimgdisplay and not the script. You can find a possible workaround here:
|
|
|
|
https://github.com/hut/ranger/issues/86#issuecomment-17346249
|
|
|
|
|
|
#### The text is too long for my terminal window and wraps to the next line causing the image to not render correctly.
|
|
|
|
There are a few ways to fix this.
|
|
|
|
* Disable line wrapping with `line_wrap=off` in the script or with the launch flag `--line_wrap off`
|
|
|
|
* The uptime and gtk info lines each have a shorthand option that makes their output smaller. You can <br \>
|
|
enable them by changing these variables or using these flags.
|
|
|
|
```sh
|
|
# In script options
|
|
uptime_shorthand="on"
|
|
gtk_shorthand="on"
|
|
gpu_shorthand="on"
|
|
|
|
# Launch flags
|
|
--uptime_shorthand on
|
|
--gtk_shorthand on
|
|
--gpu_shorthand on
|
|
```
|
|
|
|
* Edit the info array to make the subtitles shorter
|
|
|
|
* Resizing the terminal so that the lines don't wrap.
|
|
|
|
|
|
#### The text is pushed over too far to the right
|
|
|
|
The easiest way to fix this is to change the value of `--gap` or `$gap`<br \>
|
|
to a negative value. For example `--gap -10` will move the text 10 spaces to the left.
|
|
|
|
|
|
#### getgpu doesn't show my exact video card name
|
|
|
|
If your `lspci | grep "VGA"` output looks like this:
|
|
|
|
```
|
|
01:00.0 VGA compatible controller: NVIDIA Corporation Device 1401 (rev a1)
|
|
```
|
|
|
|
Instead of this:
|
|
|
|
```
|
|
01:00.0 VGA compatible controller: NVIDIA Corporation GM206 [GeForce GTX 960] (rev a1)
|
|
```
|
|
|
|
Then you're affected by the issue.
|
|
|
|
This is caused by your `/usr/share/misc/pci.ids\*` files being outdated and you can fix it<br \>
|
|
by running this command as root.
|
|
|
|
```
|
|
sudo update-pciids
|
|
```
