Welcome to the wiki!

  • 遠端連線

ssh [email protected] -p 22163

密碼：liK7wroV

  • 建立 Linux 使用著

帳號： sudo useradd -m -s /bin/sh rbean

密碼： sudo passwd rbean

修改帳號： sudo nano /etc/passwd

更改使用著集群組： sudo chown zbean:zbean /home/zbean

刪除帳號： sudo userdel -r zbean

  • 建立 協同作業 目錄

輸入：nano kong.conf

export PROJECT_NAME="Kong"
export PROJECT_USER_NAME="k101 k102 k103"
export PROJECT_DIR="/kong"

輸入：echo ‘export PROJECT_NAME="Kong"

export PROJECT_USER_NAME="k101 k102 k103"
export PROJECT_DIR="/kong"’ > kong.conf
  • 建立專案

輸入：nano my0413.1.sh

#!/bin/bash
[ "$USER" != "root" ] && echo "need root to run" && exit 1

source kong.conf

echo $PROJECT_DIR
  • 給予執行權限

輸入：sudo chmod +x my0413.1.sh

輸入：./my0413.1.sh
need root to run

輸入：sudo ./my0413.1.sh
/kong

  • 練習：請修改 my0413.1.sh, 顯示 Kong 專案名稱及成員名字

echo "Project Name : " $PROJECT_NAME
echo "Project User : " $PROJECT_USER_NAME

  • 程式範例 - my0413.2.sh

    #!/bin/bash

    source kong.conf

    for un in $PROJECT_USER_NAME do cat /etc/passwd | grep $un &>/dev/null [ $? != 0 ] && useradd -m -s /bin/bash $un done

    exit 0

  • in $PROJECT_USER_NAME : 執行 PROJECT_USER_NAME

  • un, $un : 建立的使用著。

  • &>/dev/null : 將程式結果不顯示於畫面。

  • ([ $? != 0 ] && useradd -m -s /bin/bash $un && "$un created") || echo "$un existed"

  • nano teatarg.sh

#!/bin/bash

echo $@ echo $# echo $1 echo $2

  • sudo chmod +x teatarg.sh

  • ./teatarg.sh a b c

a b c 3 a b
