Linux 命令:如何仅“查找"文本文件?

问题描述

After a few searches from Google, what I come up with is:

find my_folder -type f -exec grep -l "needle text" {} ; -exec file {} ; | grep text

which is very unhandy and outputs unneeded texts such as mime type information. Any better solutions? I have lots of images and other binary files in the same folder with a lot of text files that I need to search through.

解决方案

I know this is an old thread, but I stumbled across it and thought I'd share my method which I have found to be a very fast way to use find to find only non-binary files:

find . -type f -exec grep -Iq . {} ; -print

The -I option to grep tells it to immediately ignore binary files and the . option along with the -q will make it immediately match text files so it goes very fast. You can change the -print to a -print0 for piping into an xargs -0 or something if you are concerned about spaces (thanks for the tip, @lucas.werkmeister!)

Also the first dot is only necessary for certain BSD versions of find such as on OS X, but it doesn't hurt anything just having it there all the time if you want to put this in an alias or something.

EDIT: As @ruslan correctly pointed out, the -and can be omitted since it is implied.
