And, just for the record, should you want to find out more about commands on Linux without leaving your system (i.e. without any interaction with the Internet at all), the man command is available to present the manual pages (dates back to when there was an actual manual in early unix days) for individual commands, e.g.
man bash which will describe in quite some detail how to use the shell and man -k somekeyword will allow to search man pages. bash itself also has a help system: type "help" :-) -- Eric S Fraga via gnus (Emacs 31.0.50 2024-08-16) on Debian 12.6
