環境変数初期値確認とスクリプトによる設定

環境

SUSE Linux Enterprise Server 15（WSL）
Kernel

~/work # cat /proc/version
Linux version 4.4.0-18362-Microsoft (Microsoft@Microsoft.com) (gcc version 5.4.0 (GCC) ) #1049-Microsoft Thu Aug 14 12:01:00 PST 2020

~/work # cat /etc/os-release
NAME="SLES"
VERSION="15"
VERSION_ID="15"
PRETTY_NAME="SUSE Linux Enterprise Server 15"
ID="sles"
ID_LIKE="suse"
ANSI_COLOR="0;32"
CPE_NAME="cpe:/o:suse:sles:15"

.bashrc
- プロンプトを見やすい用に設定中（Bashプロンプトのホスト名を非表示にする）

~ # cat /root/.bashrc
export PS1="\[\]\w #\[\] "

環境変数について

【参考】環境変数 - ArchWiki
- 環境変数とは1つ、または複数のアプリケーションによって使用されるデータを含んだ名前付きオブジェクト
- 複数のアプリケーションと Linux のプロセスの設定を共有するシンプルな方法
  - 適当な環境変数設定ファイル (/etc/profile あるいは /etc/bash.bashrc) に記述することで、特定のユーザの変数PATHに○○を追加等が可能

初期状態

①起動時（＝output_env_0）

②ログイン：# su root（output_env_1）
- 注意点
  - # su [ユーザ名]では環境変数も元のユーザーのものが引き継がれる
    =事故が起きやすい
  - # su - [ユーザ名]では環境変数は変更したユーザーの初期値に設定される

①と②の違い
- 追加
  - OLDPWD=/root
- 変更
  - SHLVL=1
    - →SHLVL=2＝シェルの深さが一つ増えた
  - PATH=/sbin:/usr/sbin:/usr/local/sbin:/root/bin:/usr/local/bin:/usr/bin:/bin
    - →PATH=/sbin:/bin:/usr/sbin:/usr/bin＝
      ※消えた/usr/local/sbin, /root/bin, /usr/local/binディレクトリには現在ファイル無し

スクリプトで環境変数をカレントシェルに読み込ませる際の注意点

bashrc_test.sh
- TEST_ENVという環境変数を設定したいとする

~/work # cat bashrc_test.sh
#!/bin/bash

export TEST_ENV=test

bashコマンド（または、shコマンド）
- 子プロセスを作成しての実行のため、カレントシェルに読み込まれない

~/work # bash bashrc_test.sh
~/work # echo $TEST_ENV

~/work #

.での実行（または、sourceコマンド）
- カレントシェルでの実行（読み込み）のため、反映される

~/work # . bashrc_test.sh
~/work # echo $TEST_ENV
test
