■slコマンド
先日、qpstudyという勉強会のUSTを見ていたらslコマンドというものがあることを知りました。
slコマンドを実行するとSLのアスキーアートが走り抜けていきます。
通常は入っていないので、インストールして実行してみました。
・事前準備
yumでEPEL(Extra Packages for Enterprize Linux)を使う設定を入れる
参考サイト
CentOSでEPELやATrpmsのパッケージをyumで利用できるようにする

Nothing to do
もうすでに入ってましたね。
EPELのリポジトリの追加です。

私が使っているOSはCentOS5.7ですが、こちらの最新版が
epel-release-5-4.noarch.rpmでしたので、最新版を適用しました。

yumのオプションに-yをつけるのを忘れました…
処理の途中でyを入力するのが面倒でした。
これでslコマンドが使えるようになりました。
キャプチャをとるのが面倒だったので、画像は以下のサイトをみてみてください。

あと、ついでにfortuneコマンドも入れてみました。
fortuneコマンドは、歴史上の偉人の名言や有名人の発言などを一部引用したメッセージを
無作為に表示するコマンドです。

実行してみました。

Don't smoke the next cigarette. Repeat.
[root@bobchan ~]# fortune
I went home with a waitress,
The way I always do.
How I was I to know?
She was with the Russians too.
I was gambling in Havana,
I took a little risk.
Send lawyers, guns, and money,
Dad, get me out of this.
-- Warren Zevon, "Lawyers, Guns and Money"
?? ちょっと意味がわからないですね。。。
Linuxには色々なコマンドがありますね。
