Use the command
grep -inr <string> /path/to/directory
The -inr option has three parts:
ito ignore case sensitivity,nto display the line numbers in for each matched result, andrto recursively read all files under each directory.

/path/to/directory would actually be path to the file if you are looking in this directory itself with no recursion required. remove -r also. If name of the file is not know then *.*
parsecer
how to make it
not display the substring in result output? eg only output = filenames, nothing elseJacques
@parsecer You can use the lower L tag
grep -l (files-with-matches) for that. This also skips the rest of the file on the first match so that could be a performance improvement.Let say your string is in the environment variable STR and you search in directory dir/. You can do:
find dir/ -type f -name "*${STR}*"
If you search a file containing the string:
find dir/ -type f -exec grep -l $STR {} \;
But this is explained here

You could do
grep -nr <string> <path to the directory>
This will print the name of the files with the line number containing the string
If you want to list file name(s) with a particular string then do
find <path to the directory> -iname <string_pattern> -type f

This command will find files with matching string. However, I added little more extra, exec will list the files.
command
find <your/dir/> -name "string_to_search*" -type f -exec ls -l {} \;
or this command will list all the c files in your directory.
find <your/dir/> -name "*.c" -type f -exec ls -l {} \;
Using find command to find the matching string inside the file.
find -type f | xargs grep 'text-to-find-here'
Here / means search in all dirs
find / -type f | xargs grep 'text-to-find-here'
or
grep -r "string to be searched" /path/to/dir
