Sense a theme in issue 2 of Penguin Shell? Maybe a shell? Console? Console shell commands? True, true and true. Consistent with those themes, Linuxcommand.org is “your one-stop command line shop.” This site is rich with detail regarding the shell and writing useful shell scripts. There’s a detailed view of the directory structure, permissions, navigating through the directories, and other invaluable information about Linux in general.
Warning: prodigious and habitual use of this site can increase the risk of perpetual geekdom.
