複数プロキシ切り替えのシェルスクリプト

Ubuntuで，ターミナルから複数のプロキシを切り替えるスクリプト．

#!/bin/bash echo '--------------------------------------' echo 'Proxy Settings' echo '--------------------------------------' menu1='SHOW CURRENT PROXY' menu2='DISABLE' menu3='SET [hoge.co.jp]' menu4='SET [foo.co.jp]' menu5='QUIT' select menu in "$menu1" "$menu2" "$menu3" "$menu4" "$menu5" do     if [ -z "$menu" ]; then         continue     else         break     fi done case "$menu" in     "$menu1" )         printenv | grep proxy         $BASH_SOURCE ;;     "$menu2" )         unset http_proxy         unset https_proxy         unset ftp_proxy         unset no_proxy         echo 'printenv | grep proxy'         printenv | grep proxy         $BASH_SOURCE ;;     "$menu3" )         export http_proxy='http://hoge.co.jp:8080/'         export https_proxy='https://hoge.co.jp:8080/'         export ftp_proxy='ftp://hoge.co.jp:8080/'         export no_proxy='localhost,127.0.0.1'         echo 'printenv | grep proxy'         printenv | grep proxy         $BASH_SOURCE ;;     "$menu4" )         export http_proxy='http://foo.co.jp:8090/'         export https_proxy='https://foo.co.jp:8090/'         export ftp_proxy='ftp://foo.co.jp:8090/'         export no_proxy='localhost,127.0.0.1'         echo 'printenv | grep proxy'         printenv | grep proxy         $BASH_SOURCE ;;     "$menu5" )         echo bye ;; esac

直接実行すると，スクリプト内での環境変数の変更が，スクリプト終了時に破棄されてしまう．
なので，sourceコマンドで呼び出す．

$ source proxyswitch.sh

エイリアスを設定しておくと使いやすい．



ついでに，Windowsで同じようなことをやるバッチ．

@echo off :Menu cls echo -------------------------------------- echo Proxy Settings echo -------------------------------------- echo 1:SHOW CURRENT PROXY echo 2:ENABLE echo 3:DISABLE echo 4:SET [hoge.co.jp] echo 5:SET [foo.co.jp] echo q:QUIT echo -------------------------------------- echo Attention: it changes registry settings. echo -------------------------------------- set Slt=nul set /p Slt="input:" if '%Slt%'=='1' goto Set_1 if '%Slt%'=='2' goto Set_2 if '%Slt%'=='3' goto Set_3 if '%Slt%'=='4' goto Set_4 if '%Slt%'=='5' goto Set_5 if '%Slt%'=='q' goto :eof goto Menu :Set_1 FOR /F "TOKENS=1,2,*" %%A IN ('REG QUERY "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyEnable') DO IF "%%A"=="ProxyEnable" SET enable=%%C FOR /F "TOKENS=1,2,*" %%A IN ('REG QUERY "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyServer 2^>nul') DO IF "%%A"=="ProxyServer" SET proxy=%%C if %enable%==0x0 echo [disabled]  (%proxy%) if %enable%==0x1 echo [enabled]  %proxy% pause goto :Menu :Set_2 reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /f /v ProxyEnable /t reg_dword /d 1 echo Proxy ON reg query "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyServer pause goto :Menu :Set_3 reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /f /v ProxyEnable /t reg_dword /d 0 echo Proxy OFF pause goto :Menu :Set_4 reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyServer /t REG_SZ /d hoge.co.jp:8080 /f reg query "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyServer pause goto :Menu :Set_5 reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyServer /t REG_SZ /d foo.co.jp:8090 /f reg query "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyServer pause goto :Menu
