how to search strings in multiple files recursively

[Wang,MinJie]

Hi all
I'm not good at shell programming
I know that if you want to search one string within a directory ,you can run "grep *" to complete.
But if there is a sub directory and you also want to search,how can you do this job recursively.
What if there is another sub directory in that sub directory?
Tks in advance

Many ways to achieve this.

One is mentioned in the find man page:

Search the two directories /example and /new/example for files containing the string Where are you and print the names of the files:

find /example /new/example -exec grep -l 'Where are you' {} \;

For performance a "+" should be used instead:
find /example -exec grep -l 'Where are you' {} +
