Bash Grep Subdirectories (Recursively)

To grep for a pattern in subdirectories (recursively) in a Bash shell, you can use the grep command with the -r or --recursive option.

For example, to search for the string "test" in all files in the current directory and its subdirectories, you can use the following command:

grep -r "test" .

This will search for the string "test" in all files in the current directory and its subdirectories, and it will print the matching lines to the console.

You can customize the grep command to fit your specific needs by using various options. For example, you can use the -i option to ignore case, the -l option to print only the names of files that contain the pattern, or the -n option to print the line numbers of the matching lines.

For example, to search for the string "test" in all files in the current directory and its subdirectories and print only the names of the files that contain the pattern, you can use the following command:

grep -ril "test" .

This will search for the string "test" in all files in the current directory and its subdirectories, and it will print only the names of the files that contain the pattern.

Keep in mind that the grep command is a powerful tool that can be used to search for patterns in text files on a Linux or Unix system. You can use the various options available with the grep command to fine-tune your search and customize its behavior.
