![更改多个文件中的文本](https://linux22.com/image/1122464/%E6%9B%B4%E6%94%B9%E5%A4%9A%E4%B8%AA%E6%96%87%E4%BB%B6%E4%B8%AD%E7%9A%84%E6%96%87%E6%9C%AC.png)
我有一个 C++ 项目,每个文件的开头都有几行许可证。现在,我的许可证已经更改,我需要在每个文件中更新它。我不想手动做这件事,因为这需要大量工作。有没有办法让它更自动化?我试过了http://regexxer.sourceforge.net/但它仅在处理短文本时有用(它并没有取代我的许可证)...

我只是想在这个代码中添加几行(用新版本替换)= 但是怎么做呢?
答案1
另一种解决方案是使用awk。
创建一个像这样的新脚本changeLicense.awk
:
{
if (match($1,"^/\*.")!=0) {
i = 0; flag = "false";
comment[i++] = $0;
while(getline > 0) {
if (match($0,"Copyright") != 0) flag = "true";
comment[i++] = $0;
if (match($0,"\*/$")!=0) {
if (flag == "false") {
for (J=0; J<i; J++) print comment[J];
}
else {
while ((getline line < newLicense) > 0)
print line;
close(newLicense);
}
next;
}
}
}
print;
}
该脚本查找内部的行块/*
,*/
如果注释行块包含“Copyright”字符串,则用 newLicense 文件内容替换块,否则保留注释。
为了更改项目所有文件中的许可证:
find /path/project -name "*.cpp" -exec bash -c 'awk -f /path/changeLicense.awk -v newLicense=/path/fileWithNewContent $1 > $1.new; mv $1.new $1' _ {} \;
该脚本changeLicense.awk
在每个.cpp
文件上运行/path/project
,将结果放入.new
文件中,然后替换原始文件.cpp
在 lubuntu 12.04 上测试

如果许可证文本在每个文件中总是出现在完全相同的位置,那么您可以简单地使用sed
在给定的行号后附加新文本,例如
sed '34a \
** YOUR ADDITIONAL LICENCE TERMS\
** ADDED HERE
' file1.c
例如,您可以将其与find
将其应用于每个文件相结合.c
find -name '*.c' -exec sed -i '34a \
** YOUR ADDITIONAL LICENCE TERMS\
** ADDED HERE
' {} \;
