grep z

Linux provides a powerful toolkit for text processing, one of which is the grep command. This command is commonly used to search for patterns specified by a user. Today, we'll explore an interesting feature of grep - using the -z option to work with NUL-separated "lines." Answer: The grep -z command allows grep to treat input as a set of lines, each terminated by a zero byte (the ASCII NUL character) instead of a newline character. This is particularly useful in dealing with filenames, since filenames can contain newlines and other special characters which might be misinterpreted in standard text processing.
