how to search text contained in files in a directory recursively using command

To search for text contained in files in a directory recursively using a command, you can use the grep command in combination with the find command.

Here is the syntax to achieve this:

find <directory> -type f -exec grep -H <search_term> {} +

Let's break down the components of this command:

• <directory>: Replace this with the path to the directory in which you want to search for files.
• -type f: This option ensures that only regular files are processed (excluding directories and other types of files).
• -exec: This option allows us to execute the grep command on each file found by find.
• grep -H <search_term> {} +: This is the grep command that searches for the specified <search_term> in the files found by find. The -H option is used to print the file name along with the matching line.

For example, if you want to search for the text "example" in all files within the "/home/user/documents" directory, you would use the following command:

find /home/user/documents -type f -exec grep -H "example" {} +

This command will recursively search for "example" in all files within the specified directory and print the file name along with the matching line(s) where the text is found
