Explanation

lspci lists all PCI devices connected to the system, including HBA (Host Bus Adapter) cards used for fiber channel SAN connectivity. Piping to egrep (extended grep) allows alternation with the | operator to match either 'hba' or 'fibr' in the output. zgrep is used for searching compressed files. pgrep searches for running processes by name, not hardware listings. The fourth option (piping directly to the pattern without a grep command) is syntactically invalid.
