Using double dash to specify pesky command line parameters

Many Linux commands accept command-line options and positional parameters. The grep command searches for a pattern in a given file. Its 2 positional parameters are the pattern and the filename. It accepts options such as -i which specifies that the search is case insensitive. An interesting scenario is when a positional parameter has a value starting with a dash ('-'). This makes the parameter indistinguishable from an option. For example, you try to grep the string -tea in a given file.

But, to people like myself who still operate machines equipped with only a single 19-inch monitor, using workspaces effectively is still a big productivity booster. Below are some tips for using GNOME Classic workspaces. Tip 1: Change # of default workspaces By default, the GNOME desktop has 4 workspaces available. The default number can be changed.
