To solve this problem, you can take advantage of Linux's built-in wildcard support. This support, also called "globbing" (for historical reasons), allows you to specify multiple files at once by using a wildcard pattern. Bash and other Linux commands will interpret this pattern by looking on disk and finding any files that match it. So, if you had files file1 through file8 in the current working directory, you could remove these files by typing:

$ rm file[1-8]

Or if you simply wanted to remove all files whose names begin with file, you could type:

$ rm file*
