Find all files matching 'name' on linux system, and search with them for 'text'
提问by siliconpi
I need to find all instances of 'filename.ext' on a linux system and see which ones contain the text 'lookingfor'.
我需要在 Linux 系统上找到“filename.ext”的所有实例，并查看哪些包含文本“lookingfor”。
Is there a set of linux command line operations that would work?
是否有一组可行的 linux 命令行操作？

find / -type f -name filename.ext -exec grep -l 'lookingfor' {} +
Using a +to terminate the command is more efficient than \;because findsends a whole batch of files to grepinstead of sending them one by one. This avoids a fork/exec for each single file which is found.
使用+终止命令比更有效\;，因为find将整批文件，以grep代替送他们一个接一个。这避免了找到的每个单个文件的 fork/exec。
A while ago I did some testing to compare the performance of xargsvs {} +vs {} \;and I found that {} +was faster. Here are some of my results:
不久前我做了一些测试来比较xargsvs {} +vs的性能，{} \;我发现它{} +更快。以下是我的一些结果：
time find . -name "*20090430*" -exec touch {} +
real 0m31.98s
user 0m0.06s
sys 0m0.49s
time find . -name "*20090430*" | xargs touch
real 1m8.81s
user 0m0.13s
sys 0m1.07s
time find . -name "*20090430*" -exec touch {} \;
real 1m42.53s
user 0m0.17s
sys 0m2.42s

Try:
尝试：
find / -type f -name filename.ext -exec grep -H -n 'lookingfor' {} \;
findsearches recursively starting from the root /for files named filename.extand for every found occurrence it runs grep on the file name searching for lookingforand if found prints the line number (-n) and the file name (-H).
find从根开始递归搜索/命名的文件filename.ext，对于每个找到的出现，它在搜索的文件名上运行 grep lookingfor，如果找到，则打印行号 ( -n) 和文件名 ( -H)。

A more simple one would be,
一个更简单的方法是，
find / -type f -name filename.ext -print0 | xargs -0 grep 'lookingfor'
-print0 to find & 0 to xargs would mitigate the issue of large number of files in a single directory.
-print0 to find & 0 to xargs 将缓解单个目录中大量文件的问题。

Go to respective directory and type the following command.
转到相应的目录并键入以下命令。
find . -name "*.ext" | xargs grep 'lookingfor'
找 。-name "*.ext" | xargs grep '寻找'

I find the following command the simplest way:
我发现以下命令是最简单的方法：
grep -R --include="filename.ext" lookingfor
or add -ito search case insensitive:
或添加-i到不区分大小写的搜索：
grep -i -R --include="filename.ext" lookingfor
