ls -a      ######## lists all files, including the ones whose filenames begin in a dot, which you do not always want to see.

more filename      ######## shows the first part of a file, just as much as will fit on one screen. Just hit the space bar to see more or q to quit. You can use /pattern to search for a pattern.
