grep only text files
提问by stefcud
find . -type f | xargs file | grep text | cut -d':' -f1 | xargs grep -l "TEXTSEARCH" {}
it's a good solution? for find TEXTSEARCH recursively in only textual files
这是一个很好的解决方案吗？仅在文本文件中递归查找 TEXTSEARCH

You can use the -r(recursive) and -I(ignore binary) options in grep:
您可以在以下位置使用-r(recursive) 和-I(ignore binary) 选项grep：
$ grep -rI "TEXTSEARCH" .
-IProcess a binary file as if it did not contain matching data; this is equivalent to the--binary-files=without-matchoption.-rRead all files under each directory, recursively; this is equivalent to the-d recurseoption.
-I处理一个二进制文件，就好像它不包含匹配的数据一样；这相当于--binary-files=without-match选项。-r递归读取每个目录下的所有文件；这相当于-d recurse选项。

Another, less elegant solution than kevs, is, to chain -exec commands in find together, without xargs and cut:
另一个不如 kevs 优雅的解决方案是，将 find 中的 -exec 命令链接在一起，而无需 xargs 和 cut：
find . -type f -exec bash -c "file -bi {} | grep -q text" \; -exec grep TEXTSEARCH {} ";"

If you know what the file extension is that you want to search, then a very simple way to search all *.txt files from the current dir, recursively through all subdirs, case insensitive:
如果您知道要搜索的文件扩展名是什么，那么可以通过一种非常简单的方法从当前目录中搜索所有 *.txt 文件，递归遍历所有子目录，不区分大小写：
grep -ri --include=*.txt "sometext" *
grep -ri --include=*.txt "sometext" *
