On my Linux command line, when I type a letter, or a group of letters (such as 'fr','nan', or 'ca'), pressing the tab key twice lists the following (using the above examples):
free freetype-config from
cabal calendar callgrind_control case catchsegv
cake caller capsh caspol catman
cal callgrind_annotate captoinfo cat cautious-launcher
- Am I correct to assume that this is a shortcut to view all available commands beginning with the typed words (fr*, nan*, or ca*) (where, in this example, '*' is used as a wildcard)?
- Does this work on all command lines, or is this Linux specific?
- What is this feature called, and are there other similar command line shortcuts?
- Where can I find documentation on this shortcut?
