使用python生成shell腳本

Question

嗨，我目前正在開發一個 python 腳本，該腳本生成 shell 腳本以在 linux 服務器上安裝代理。 python 腳本輸出的 .sh 文件一直以“語法錯誤：文件意外結束”結尾，但是當我在 vi 中手動輸入確切的輸出時，似乎沒有問題。 我在 python 中編寫它的方式有什么問題，或者通過 python 編寫它是否可行？

main()

上面腳本的輸出

agent="/opt/test/ragent/bin/racli"
installer="/opt/test/installer/bin/racli"
if [ ! -e "$agent" ]; then
./agent1.bsx -n -d /opt/test
else
echo "Agent is already installed"
fi
if [ ! -e "$installer" ]; then
./installer1.bsx -n -d /opt/test
else
echo "Manager is already installed"
fi
/opt/test/ragent/bin/cli registration advanced-register registration-type=Primary ragent-name=agent1 gw-ip=10.255.0.80 gw-port=443 manual-settings-activation=Automatic monitor-networkchannels=Both password=$1
/opt/test/ragent/bin/cli registration advanced-register registration-type=Secondary ragent-name=agent1 gw-ip=10.255.0.81 gw-port=443 manual-settings-activation=Automatic monitor-networkchannels=Both password=$1

/opt/test/installer/bin/cliinstaller registration register-use-existing package-folder-path="." package-folder-size=1024
/opt/test/installer/bin/rainstallerinit start

它從中讀取的 csv 文件

Agent Name,Agent File,Installer File,Primary IP,Secondary IP,Type
agent1,agent1.bsx,installer1.bsx,10.255.0.80,10.255.0.81,Linux
agent2,agent2.bsx,installer2.bsx,10.255.0.81,,Linux

Windows 上的換行約定是\\r\\n 。 Bash 將換行符解釋為...換行符，而\\r是bash的普通字符。

使固定：

sf = open(agentname+ "_install.sh", "w", newline='\n')
