sh 腳本中的 sed 和 awk 不替換文本

查找字元串並替換為另一個（所有發生）以及重寫/更新文件的所需工作。

該文件是一個pbxproj文件。我連結了這個文件的一個樣本

文件範例*（請注意此文件太大，無法在此處共享非工作範例。您可以查看之前的連結）*：

#!/bin/sh

cpath=$(cd -P -- "$(dirname -- "$0")" && printf '%s\n' "$(pwd -P)/")
xcodePath="${cpath}ios/Runner.xcodeproj/project.pbxproj"

sed -i -e 's/MARKETING_VERSION = 1.1.1/MARKETING_VERSION = 1.1.2/g' xcodePath

# or tried with awk too

# awk '{gsub("MARKETING_VERSION = 1.1.1","MARKETING_VERSION = 1.1.2"); print}' xcodePath

完成後，我檢查了文件，沒有任何改變。沒有錯誤，沒有警告！有什麼辦法可以解決嗎？

您的腳本無法使用“$”擴展變數 xcodepath。喜歡：

sed -i -e 's/MARKETING_VERSION = 1.1.1/MARKETING_VERSION = 1.1.2/g' "$xcodePath"

要在 shell 中獲取變數的值，您需要在它前面加上$（並引用它，除非您有非常特殊的需要不引用它）所以xcodePath需要"$xcodePath".

您還需要轉義.元字元並錨定正則表達式，否則您會不希望地更改MARKETING_VERSION = 1.1.10或MARKETING_VERSION = 12151，例如，更改為MARKETING_VERSION = 1.1.2. 您也不需要重複字元串MARKETING_VERSION = 1.1.來將最後一位數字從 1 更改為 2，只需使用擷取組即可。

sed -Ei 's/(\<MARKETING_VERSION = 1\.1\.)1;/\12;/' "$xcodePath"

您已經在使用 GNU sed 了，-i所以我添加了-E只是這樣我們就不需要轉義擷取組中的括號。
