使用 find + cat 获取我“grep”的文件

Question

I am trying to get the file name where the grepped text belongs.

I use this:

find . -type f -name "*py" -exec cat -n {} \; | grep -H login.html

and I obtain this:

(standard input):    11     url(r'^login$', LoginView.as_view(template_name='dojo/login.html', authentication_form=AuthenticationForm), name='login'),

Usually I use the option -a with cat also, when I get "standard input" log, but here, since I "cat" every file, I am not sure how to proceed.

Regards.

Answer 1

You can do this entirely with Grep

grep -R -H --include="*.py" login.html

-R = Rescursion

-H = Add filenames

--include= Glob for file (similar to your -name of find)

Answer 2

I suggest using xargs: find. -type f -name "*py" | xargs grep -H login.html find. -type f -name "*py" | xargs grep -H login.html find. -type f -name "*py" | xargs grep -H login.html . You might need to use -print0 option in find and -0 in xargs if your file names contain spaces. What xargs does is to pass output of the previous command (basically its own stdin) as command arguments to its argument
