Locomotive 無法在 Debian 系統上運作: sl ls

Locomotive 無法在 Debian 系統上運作: sl ls

問題:

我安裝了sl,但是當我sl在命令列上輸入時,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).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

Sl 是一個可以顯示動畫的程序,旨在在您錯誤輸入“sl”時糾正您。 SL 代表蒸汽機車。 Debian 軟體包上的軟體包


cyberciti.biz/ 上的安裝說明

摘抄:

安裝sl軟體即可取得蒸氣機車(shell火車)

Debian在/Ubuntu Linux上鍵入以下 apt-get 指令/apt 指令:

$ sudo apt-get install sl

用法

好的,只是將 ls 指令誤輸入為 sl:

$ sl

問題:

這裡發生了什麼事,機車在哪裡,我需要配置什麼......?

答案1

如果你正在運行root(我猜你可能是因為你apt直接運行),PATH預設將排除/usr/local/gamesand/usr/games由於條件/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.
