That wasn't a pipe character, it was a lowercase 'L'. What '!!' does is pipe the current line into the command specified. I was using that to load the result of an 'ls' into the buffer. This command replaces what is on the current line with the result of the command. Then the command :%!wc means the following : - enter ex command mode % - on the entire buffer ! - pipe through command wc - the command to use (wc in this case) You can replace the '%' with any vim motion in order to pipe only certain lines through a command. You can even select an area in visual mode, type '!' and then enter your command, and it will filter that area through the command. Note that this always replaces what was there with the output of the command, though. Type :help filter in command mode for more information.
