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，

オプション結構多いです． とりあえず素で実行．
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．
