What is the Linux command to search for text in files?

The Linux command to search for text in files is find. The syntax for find is:find [options] fileName. The options are -name pattern and -type type. The pattern can be a filename or a regular expression. The type can be either "string" or "directory". If the type is not specified, then it defaults to "string".

If the pattern does not match any files in the directory, then find returns an empty list of results. If the pattern matches one or more files, then find prints out all of the matching lines from those files.

To exclude certain types of files from being searched, use the -exclude option. For example, you can search only for text files by using the -name 'text' option and specifying no type parameter:find .
