Locomotive 无法在 Debian 系统上运行: sl ls

Locomotive 无法在 Debian 系统上运行: sl ls

问题:

我安装了sl,但是当我sl在命令行上输入时,我得到:

bash: sl: command not found

(root@host)-(03:55:38)-(/home/user)
$apt install sl
Reading package lists... Done

sl is already the newest version (3.03-17+b2).

Sl 是一个可以显示动画的程序,旨在在您错误输入“sl”时纠正您。 SL 代表蒸汽机车。 Debian 软件包上的软件包


cyberciti.biz/ 上的安装说明

摘抄:

安装sl软件即可获得蒸汽机车(shell火车)

Debian在/Ubuntu Linux上键入以下 apt-get 命令/apt 命令:

$ sudo apt-get install sl

用法

好的,只是将 ls 命令误输入为 sl:

$ sl

问题:

这里发生了什么事,机车在哪里,我需要配置什么......?

答案1

如果你正在运行root(我猜你可能是因为你apt直接运行),PATH默认情况下将排除/usr/local/gamesand/usr/games由于条件/etc/profile

if [ "`id -u`" -eq 0 ]; then
  PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
else
  PATH="/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games"
fi
export PATH

sl恰好在/usr/games.
