What happens when you type ls *.c
This is a wonderful example of how wildcards can be used to enhance the use of the ls command. Basically when ls*.c is entered in the command line it will print whatever files end with the .c file extension. The * in the command represents all file names however it can be used to find files named the matching string/character. Here is some syntax for the command ls using wildcards ( ls [h*.js] ) this command will display and files starting with an lowercase h and ending the the .js file extension.
Another example:
As you can see the regular ls command displays all the files in the directoy minus any hidden files. However when we used the ls 0* it only displayed any files starting with a zero.
Now you can use ls and wildcards to your advantage!
