Tab completion, part II
Posted on September 9th, 1997 by shacker
This is an add-on to the Tab Completion tip.
If you’re trying to remember the name of a particular command, and can only think of the first one or two letters, just type those letters and hit Tab twice. All available commands starting with that letter or letters will appear in a list.
The same trick works when constructing a command looking for the names of files to operate on — typing a letter and hitting Tab twice will show a list of all allowable filenames.
