# fetch This is the home of my fetch script! This script gathers info
about your system and prints it to the terminal next to an image of your choice! **NOTE: See this wiki page for info on the new info function and it's usage** https://github.com/dylanaraps/fetch/wiki/Customizing-Info ![1](http://i.imgur.com/oTxq5fA.png) ## Table of Contents - [Features](#features) - [Dependencies](#dependencies) - [Installation](#installation) - [Post Install](#post-install) - [Usage](#usage) - [Frequently Asked Questions](#frequently-asked-questions) - [Issues and Workarounds](#issues-and-workarounds) - [Todo](#todo) - [Thanks](#thanks) ## Features - **Supports Linux, Mac OS X, BSD and Windows (Cygwin)!** - If the script doesn't work on your system, open an issue. - **It's Fast** - The script makes heavy use of bash builtins and
string manipulation. - **Display an image next to the info. (or don't!)** - Use your current wallpaper, shuffle through a directory or just
display an image of your choice. - Supports using w3m or iTerm2 to display the images. - **Highly Customizable** - You can customize almost everything. - See Usage below or lines 23-233 in script - **Take a screenshot at the end.** - It's disabled by default and you can specify the cmd
to use with `--scrotcmd cmd` at launch or by
changing the value of `$scrotcmd` in the script. - **Smart crop (or Waifu crop)** - See https://github.com/dylanaraps/fetch/wiki/What-is-Smart-Crop%3F ## Dependencies ### Required dependencies: **All OS:** - `Bash 4.0+` - Text formatting, dynamic image size and padding: `tput` **Linux / BSD / Windows:** - Uptime detection: `procps` or `procps-ng` ### Optional dependencies: **All OS:** - Displaying Images: `w3m` - You may also need `w3m-img` - **Note:** The script can now also use iTerm2's builtin image rendering instead of w3m! - Enable it by changing `image_backend` to `iterm2` or by using the launch flag `--image_backend`. - Image Cropping, Resizing etc: `ImageMagick` - Window manager detection: `wmctrl` - This is used as a fallback to parsing `.xinitrc` and `$XDG_CURRENT_DESKTOP`. **Linux / BSD:** - Display Wallpaper: `feh` or `nitrogen` - Current Song: `mpc` or `cmus` - Resolution Detection: `xorg-xdpyinfo` - Take a screenshot on script finish: `scrot` - You can change this to another program with a `--scrotcmd` and an in script option. ## Installation ### Arch 1. Install **[fetch-git](https://aur.archlinux.org/packages/fetch-git/)** from the aur. ### Others 1. Download the latest source at https://github.com/dylanaraps/fetch 2. Make the file executable using chmod. `chmod +x /path/to/fetch` 3. Move the script to somewhere in your $PATH or just run it from where it is. ## Post Install #### Sizing the image correctly **NOTE:** For the images to be sized correctly you need to set the `$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 \ " ``` ## Usage usage: ${0##*/} [--colors 1 2 3 4 5] [--kernel "\$\(uname -rs\)"] Info: --speed_type Change the type of cpu speed to display. Possible values: current, min, max, bios, scaling_current, scaling_min, scaling_max NOTE: This only support Linux with cpufreq. --uptime_shorthand Shorten the output of uptime --gpu_shorthand on/off Shorten the output of GPU --gtk_shorthand on/off Shorten output of gtk theme/icons --gtk2 on/off Enable/Disable gtk2 theme/icons output --gtk3 on/off Enable/Disable gtk3 theme/icons output Text Colors: --colors 1 2 3 4 5 Change the color of text (title, subtitle, colon, underline, info) --title_color num Change the color of the title --subtitle_color num Change the color of the subtitle --colon_color num Change the color of the colons --underline_color num Change the color of the underlines --info_color num Change the color of the info Text Formatting: --underline on/off Enable/Disable title underline --underline_char char Character to use when underlineing title --line_wrap on/off Enable/Disable line wrapping --bold on/off Enable/Disable bold text --prompt_height num Set this to your prompt height to fix issues with the text going off screen at the top Color Blocks: --color_blocks on/off Enable/Disable the color blocks --block_width num Width of color blocks --block_range start end --v Range of colors to print as blocks Image: --image Image source. Where and what image we display. Possible values: wall, shuffle, /path/to/img, off --shuffledir Which directory to shuffle for an image. --font_width px Used to automatically size the image --image_position Where to display the image: (Left/Right) --split_size num Width of img/text splits A value of 2 makes each split half the terminal width and etc --crop_mode Which crop mode to use Takes the values: normal, fit, fill --crop_offset value Change the crop offset for normal mode. Possible values: northwest, north, northeast, west, center, east, southwest, south, southeast --xoffset px How close the image will be to the left edge of the window --yoffset px How close the image will be to the top edge of the window --gap num Gap between image and text right side to the top edge of the window NOTE: --gap can take a negative value which will move the text closer to the left side. --clean Remove all cropped images Screenshot: --scrot /path/to/img Take a screenshot, if path is left empty the screenshot function will use \$scrot_dir and \$scrot_name. --scrot_cmd Screenshot program to launch Other: --help Print this text and exit ## Frequently Asked Questions #### 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 getting the current wallpaper from the cli. If your wallpaper setter **does** provide a way of getting the current wallpaper
or you know where it's stored then adding support won't be a problem!
## Issues and Workarounds #### 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 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 `$line_wrap off` in the script or with the launch flag `--line_wrap off` * The uptime and gtk info lines each have a shorthand option that makes their output smaller. You can
enable them by changing these variables or using these flags. ```sh # In script options uptime_shorthand="on" gtk_shorthand="on" gpu_shorthand="on" # Launch flags --uptime_shorthand on --gtk_shorthand on --gpu_shorthand on ``` * Edit the info array to make the subtitles shorter * Resizing the terminal so that the lines don't wrap. #### The text is pushed over too far to the right The easiest way to fix this is to change the value of `--gap` or `$gap`
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
by running this command as root. ``` sudo update-pciids ``` ## Todo Here's what's on my todo list - More info outputs. Now that it's easy to customize what's printed and
everything is a function we can add optional support for pretty much anything. - Resolution (Just missing Windows support) - ~~GTK themes~~ - Terminal Font - This will be difficult to add as there's no standard way of getting this info. We can't check
for terminal config files because the user may have multiple terminals installed.
Using `$PPID` isn't an option because it won't work in tmux/screen, subshells or neovim terminal splits. - GPU (In master but experimental) See **[issue #21](https://github.com/dylanaraps/fetch/issues/21)**. ## Thanks Thanks to: - metakirby5: Providing great feedback as well as ideas for the script. - Screenfetch: I've used some snippets as a base for a few functions in this script. - @jrgz: Helping me test the Mac OS X version. - @xDemonessx: Helping me test the Windows version.
