所需的工作是找到一个字符串，然后替换为另一个字符串（所有情况），并重写/更新文件。
文件就是pbxproj文件。我链接了该文件的示例
文件样本（请注意，此文件太大，无法在此处共享非工作示例。您可以之前检查链接）：

# or tried with awk too
# awk '{gsub("MARKETING_VERSION = 1.1.1","MARKETING_VERSION = 1.1.2"); print}' xcodePath
完成后我检查了文件，没有任何变化。没有错误，没有警告！有什么办法可以修复吗？
答案1
您的脚本无法使用“$”扩展变量 xcodepath。喜欢：
sed -i -e 's/MARKETING_VERSION = 1.1.1/MARKETING_VERSION = 1.1.2/g' "$xcodePath"
答案2
要在 shell 中获取变量的值，您需要在其前面加上前缀$（并引用它，除非您有非常具体的需要不引用它），所以xcodePath需要是"$xcodePath"。
您还需要转义.元字符并锚定正则表达式，否则您可能会意外地将MARKETING_VERSION = 1.1.10or更改MARKETING_VERSION = 12151为MARKETING_VERSION = 1.1.2。您也不需要重复字符串MARKETING_VERSION = 1.1.只是为了将最后一位数字从 1 更改为 2，只需使用捕获组即可。
sed -Ei 's/(\<MARKETING_VERSION = 1\.1\.)1;/\12;/' "$xcodePath"
您已经使用了 GNU sed，-i所以我添加了-E这样的内容，这样我们就不需要转义捕获组中的括号。
