Press [↑] repeatedly until cd ~ appears.
2 Press [Enter] to execute the command and to switch to your home directory.
By default, your home directory contains two subdirectories starting with the
same letter, Documents and Desktop.
3
Enter cd D and press [→|].
Nothing happens since Bash cannot identify to which one of the subdirectories
you want to change.
4 Press [→|] again to see the list of possible choices:
tux@knox:~> cd D Desktop/ Documents/ tux@knox:~> cd D
5 The prompt still shows your initial input. Type the next character of the subdi-
rectory you want to go to and press [→|] again.
Bash now completes the path.
6 You can now execute the command with [Enter].
Procedure 7.7 Using Wildcards
Now suppose that your home directory contains a number of les with various le
extensions. It also holds several versions of one le which you saved under dierent
lenames myfile1.txt, myfile2.txt etc. You want to search for certain les accord-
ing to their properties.
1 First, create some test les in your home directory:
1a
Use the touch command to create several (empty) les with dierent
le extensions, for example .pdf, .xml and .jpg.
You can do this consecutively (do not forget to use the Bash history
function) or with only one touch command: simply add several le-
names separated by a space.
1b Create at least two les that have the same le extension, for exam-
ple .html.
1c To create several “versions” of one le, enter
touch myfile{1..5}.txt
This command creates ve consecutively numbered les:
myfile1.txt,…,myfile5.txt
