可愛いシステム情報表示ツールのpfetch

screenfetchやneofetchと同じようなものですが,shell script 1本で動いてロゴが可愛いです.

現在のバージョンではロゴはこれだけあるよう.

環境変数 PF_INFOPF_ASCII で指定したものを表示できるようです.そこでこういうscriptで表示して,

#!/usr/bin/perl
use strict;
use warnings;
use Time::HiRes 'sleep';

my @LIST=('alpine','android','arch','arco','artix','centos','debian','dragonfly','elementary','fedora','freebsd','gentoo','guixsd','haiku','hyperbola','lite','linux','macos','mageia','manjaro','mint','minix','mx','netbsd','nixos','openbsd','suse','parabola','pop!_os','pureos','slackware','sunos','ubuntu','void');

foreach my $dist ( sort @LIST ){
  my $pfetch = `clear`;
  $pfetch .= "$dist\n";
  $pfetch .= `PF_INFO=ascii PF_ASCII=$dist pfetch`;
  print $pfetch;
  sleep(0.5);
}
`PF_INFO=ascii pfetch > /dev/null`;
print "done\n";

asciinemaへのアップロード……に失敗したのでttyrecして,ttygifしてみました.

pfetch logos
$ ttyrec pfetch.tty # 録画開始
$ perl pfetch-logo.pl # logo表示
$ exit  # 録画終了
$ vi pfetch.tty # テキストエディタで頭と最後のゴミ削除
$ resize -s 11 25 # terminalを小さくしておく
$ ttygif -in pfetch.tty # gifに書き出し
$ WINDOWID=`xdotool getactivewindow` ttygif -in pfetch.tty # `cannot get screenshot` と言われる場合

元のロゴはこの ufetch の一部が使われているよう.こちらにはRaspbianもありますね.

Screenfetch的な情報表示コマンドのNeofetch

Screenfetch的な情報表示コマンドのNeofetch

よくデスクトップのキャプチャを取得するときに表示されているScreenfetchコマンドというものがあります.システムの情報とアスキーアートを素敵に表示してくれます. これににたものでNetfetchというものを見かけたので試してみました.こちらは画像も扱えるようです.

導入

以下のページに各種環境への導入方法が書かれています.

Debian sid/stretchにはパッケージがあるようなことが書かれていますが,

Neofetch is in Debian Unstable/Stretch's official repositories.

今はsidのみのようです.

ということでひとまずstretchではこんな感じで導入しました.

$ #-- /etc/apt/sources.list.d/neofetch を作る
$ sudo apt edit-sources neofetch
$ cat /etc/apt/sources.list.d/neofetch.list
deb http://dl.bintray.com/dawidd6/neofetch jessie main
$ #-- 鍵のインポート
$ wget "https://bintray.com/user/downloadSubjectPublicKey?username=bintray" -O Release-neofetch.key
$ gpg Release-neofetch.key

$ sudo apt-key add Release-neofetch.key
$ rm Release-neofetch.key
$ #-- pkg情報更新&pkg導入
$ sudo apt update
$ sudo apt install neofetch

情報もScreenfetchより増えています.

次は画像を指定してみます.画像サイズが大きかったので25%に縮小もしています. 楽しい :)

画像の表示については環境によってうまく行く行かないがあるようです.うまく表示されない場合は以下のWikiを参照すると良さそうです.
