UNIX Wildcards

There are several special characters that can be used to match multiple files at the same time:

   ?   Matches any one character in a filename.

   *   Matches any character or characters in a filename.

   [ ]  Matches one of the characters included inside
       the [ ] symbols.

For example, suppose that the current directory contains the files

    date out1 out2 out3 prog.f prog.o

Some examples of file names and files that would be matched are:

   Filename      Files matched

    out?          out1 out2 out3
    prog.[fo]     prog.f prog.o
    *             date out1 out2 out3 prog.f prog.o
    *.f           prog.f
    out*          out1 out2 out3
