The Linux system uses the "tab" key to make up the filename

After starting Linux, enter the character interface input command, sometimes input a lot of characters, if often such step-by-step input, will be more trouble.

Assuming that the character you enter determines the next unique file for the directory, you can automatically make the remainder of the file name available by using the Keyboard's TAB key. For example, to unpack the file "ddddddd-1.2.3.tar.gz" under the Directory "/CCC" and enter "Tar xvfz/ccc/d" in the command, if the file is the only file in this directory that starts with D, you can press the "tab" key directly, The command is automatically padded: "Tar xvfz/ccc/ddddddd-.1.2.3.tar.gz", which increases the efficiency of the input.
