"halcmd show" will show pin names as well. You can also use halcmd in interactive mode; type "halcmd -f" at the shell prompt, and halcmd will display a "halcmd: " prompt. You can then use commands like "show pin", complete with wildcards, tab completion, and all the goodies. For example: "show pin gla*" will show all pins whose names start with glade. Anything you can type in a hal file you can type at the halcmd prompt. Type "quit" at the halcmd prompt when you are done, and you will wind up back at the shell prompt.
