Project $2-9$

Wildcards are handy when you want to find or work on files that have a specific sequence of characters or when you are searching for a file and are not certain of the correct spelling of that file name. In this project, you will use the $*$ and $?$ wildcards with the ls command.

To work with wildcards:

$1.$ To practice using wildcards, you first must create a set of files with similar names. In Chapter $1,$ you used the cat command to create the notes file. Use the cat command now to create these five files:

first$\_$name$$A file containing your first name middle$\_$name$$A file containing your middle name last$\_$name$$A file containing your last name full$\_$name$1.$txt$$A file containing your full name full$\_$name$22.$txt$$Another file containing your full name

$2.$ For example, type cat $>$ first$\_$name, press Enter, type your first name, press Enter, and press Ctrl$+$d$.$

$3.$ Type ls $*$name and press Enter. You see first$\_$name, last$\_$name, and middle$\_$name listed.

$4.$ Type ls full$\_$name?.txt and press Enter. You see full$\_$name$1.$txt listed.

$5.$ Type ls $*.$txt and press Enter. Now, you see full$\_$name$1.$txt and full$\_$name$22.$txt

listed.
