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, <br \>
|
|
your distro's logo or any ascii art of your choice!

## Features
|
|
|
|
- Supports **Linux**, **Mac OS X**, **BSD (FreeBSD, OpenBSD & NetBSD)** and **Windows** (Cygwin)
|
|
- Display a **full color image**, a file containing **ascii art** or your **distro's logo** in ascii next to the info.
|
|
- The script is **fast**. We use bash builtins wherever possible and only spawn external processes when necessary.
|
|
- Take a screenshot of your desktop on script finish.
|
|
- Customize **which** info is displayed, **where** it's displayed and **when** it's displayed.
|
|
- See this **[wiki page](https://github.com/dylanaraps/fetch/wiki/Customizing-Info)**

|
|
|
- `wmctrl` \[3\]

## Post Install
|
|
|
|
|
|
#### Using the config file
|
|
|
|
Fetch will by default create a config file at `$HOME/.config/fetch/config` and this file<br \>
|
|
contains all of the script's options/settings. The config file allows you to keep your<br \>
|
|
customizations between script versions and allows you to easily share your customizations<br \>
|
|
with other people.
|
|
|
|
You can launch the script without a config file by using the flag `--config none` and you can<br \>
|
|
specify a custom config location using `--config path/to/config`.
|
|
|
|
|
|
#### Sizing the image correctly
|
|
|
|
**NOTE:** For the images to be sized correctly you need to set the `$font_width` variable.<br \>
|
|
If you don't know your font width in pixels keep trying values until the image is half the<br \>
|
|
terminal width.
|
|
|
|
Once `font_width` is set the image will by default take up half the terminal width. You can<br \>
|
|
use the launch flag `--size px` or change the config option `$image_size` to set it to a custom<br \>
|
|
size in pixels.
|
|
|
|
You can also use the launch flag `--font_width` to set it on the fly.
|
|
|
|
|
|
#### Setting the prompt height
|
|
|
|
If your shell prompt's height is greater than 1 line high, you'll need to change a config<br \>
|
|
option to avoid issues with the top lines in the script output getting cut off. Set the variable<br \>
|
|
`$prompt_height` to your shell prompt's height in lines or use the launch flag `--prompt_height`.
|
|
|
|
|
|
#### Customizing what info gets displayed
|
|
|
|
In the config file there's a function that allows you to customize all of the info that<br \>
|
|
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 use the config file 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 {{{ -->

## Frequently Asked Questions
|
|
|
|
|
|
#### How do I enable screenfetch mode?
|
|
|
|
Launching the script with `--ascii distro` or setting `ascii="distro"` and `image="ascii"` <br \>
|
|
inside the config file will launch the script in "screenfetch mode". The script will<br \>
|
|
display your distro's ascii next to the info, exactly like screenfetch.
|
|
|
|
**NOTE:** If you don't have `w3m-img` or `imagemagick` installed screenfetch mode will be<br \>
|
|
used automatically
|
|
|
|
|
|
|
|
|
|
#### Why doesn't fetch support my wallpaper setter?
|
|
|
|
It's hard to add support for other wallpaper setters as they don't provide a way of <br \>
|
|
getting the current wallpaper from the cli.
|
|
|
|
If your wallpaper setter **does** provide a way of getting the current wallpaper or you<br \>
|
|
know where it's stored then adding support won't be a problem!<br \>

|
## Issues and Workarounds
|
|
|
|
|
|
#### The text is too long for my terminal window and wraps to the next line
|
|
|
|
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
|
|
# Config options
|
|
uptime_shorthand="on"
|
|
gtk_shorthand="on"
|
|
gpu_shorthand="on"
|
|
birthday_shorthand="on"
|
|
|
|
# Launch flags
|
|
--uptime_shorthand on
|
|
--gtk_shorthand on
|
|
--gpu_shorthand on
|
|
--birthday_shorthand on
|
|
|
|
```
|
|
|
|
* Edit the config 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
|
|
```
