The * Wildcard

The * wildcard means 'any characters, including no characters'. For example, suppose we have created the following files in our current working directory:

% ls
myfile myfile2 myfile3 test yourfile

To list only the file names beginning with 'myfile', we could type

% ls myfile*
myfile myfile2 myfile3
Even though test and yourfile exist, ls displayed only the file names that start with 'myfile'. If we wanted to list the file names containing 'file', we could type:
% ls *file*
myfile myfile2 myfile3 yourfile
