The output file list includes plain text, scripts, formatted text, and source code files. Here we are going to use grep and find Linux commands to do the search. The grep command needs to be modified accordingly, putting the other character used as a separator in place of “:”. In the rare case in which some of the files contain the character “:” as part of their name, we can use the -F argument of the file command to use some character other than the “:” character as the separator. In other words, the expression means “search for a : in the file command output followed by any number of characters “.*” and then the sub-string ” text”. The expression “.*” ensures that the sub-string ” text” is only searched in the file type description, not in the filename. The subsequent grep command filters all files with “ASCII text” or “UTF-8 Unicode text” as part of the file type description.

grep -r 'computerhope' /www/ In the above example, grep searches the /www/ directory and all subdirectories for the. In the following command, grep will use all the available text files in the current directory for searching the pattern. To do this, you'd type a command similar to the following example.

The file * command prints a list of filenames followed by the file type description of all files in the current directory. The above example would only search the current directory.
