The command "bzfgrep --only-matching "${search_string}" ${filename}" is used to search for a specific pattern or string within a compressed file (.bz2) and display only the matching portions.

Here is a breakdown of the command:

• "bzfgrep" is a command used to search for patterns within a bzipped file.
• "--only-matching" is an option with the command that mandates the output to show only the matched parts of each line instead of the entire line.
• "${search_string}" refers to the variable that contains the pattern/text you want to search for. You should replace it with the actual pattern you are searching for.
• "${filename}" refers to the variable that contains the name of the file (.bz2 format) you want to search in. You should replace it with the actual file name.

To use this command, replace "${search_string}" and "${filename}" with the desired pattern and file name, respectively. The command will then display only the matching portions of the lines that contain the given pattern in the specified file.
