Shortcut Key
Now, we will introduce several shortcuts that are very useful and commonly used in terminal.
1. up and down arrow keys. History commands can be quickly brought back by using up and down arrow
keys, which are very useful when you need to reuse certain commands.
When you need to type command, pressing “↑” will bring back the previous command, and pressing “↓” will
bring back the latter command.
2. Tab key. The Tab key can automatically complete the command/path you want to type. When there are
multiple commands/paths conforming to the already typed letter, pressing Tab key once won’t have any result.
And pressing Tab key again will list all the eligible options. This command/path will be directly completed
when there is only one eligible option.
As shown below, under the'~'directory, enter the Documents directory with the “cd” command. After typing
“cd D”, press Tab key, then there is no response. Press Tab key again, then all the files/folders that begin with
“D” is listed. Continue to type the character "oc", then press the Tab key, and then “Documents” is completed
automatically.
