    press Control-V Tab instead; Tab is bound to file/command completion by default.

When you press Enter after entering an incomplete command, the bash shell will show a continuation prompt (the secondary prompt, $PS2) and allow you to complete the entered command. The command line editing facilities of the shell at that point is the same as at the original prompt (the primary prompt, $PS1), which means that the Tab key would do command and filename completion as usual.



To insert a tab character, use Ctrl+V Tab, or use spaces for indentation. Tab characters (or any other literal character) can always be inserted if prefixed by Ctrl+V.



Alternatively, if in Emacs command line editing mode (which I believe is the default in bash), use Ctrl+X Ctrl+E to bring up an editor to enter your command into. The editor used will be the one specified by the EDITOR shell/environment variable, or emacs if this variable is unset.



In Vi command line editing mode, press Escape v to do the same thing.



The command will be executed after saving and exiting the editor.

  • Could I ask What's vi command line, I am aware the Vim is a editor which should be opened in advance, go inside, and edit, rather than directly type into command and run.

Confectionery

Prepared foods made with a lot of sugar or other cabohydrates "Sweetmeat" redirects here. For the racehorse, see Sweetmeat (horse). Not to be confused with Sweetbread. This Kransekake is a traditional Scandinavian baker's confection. Confectionery is the art of making confections , which are food items that are rich in sugar and carbohydrates. Exact definitions are difficult. [1] In general, though, confectionery is divided into two broad and somewhat overlapping categories, bakers' confections and sugar confections. [2] Bakers' confectionery, also called flour confections , includes principally sweet pastries, cakes, and similar baked goods. Sugar confectionery includes candies ( sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar. In some cases, chocolate confections (confections made of chocolate) are treated as a separate category, as are sugar-free versions of ...
