. To enter several commands on the one command line, use a ; (semicolon) to seperate each one from the next. For example: cd ..; ls -l . This command line contains two commands. The first, cd .. changes the current directory to the parent directory. The second, ls -l produces a long listing of the contents of the curent directory. If necessary you can continue the commands onto another line.
