One-line tip: ? and * - China DOS Union Forum - China DOS Union

? and * are both filename wildcards used by DOS. The difference is that one ? can stand for any one character in the current position, while * can stand for many characters.
For example, suppose the current directory has the following files

a.cab a1.bas b1.bas abcd.bas ab.bas

dir a?.bas will list a1.bas ab.bas
dir a*.bas will list a1.bas abcd.bas ab.bas
dir ?1.bas will list a1.bas b1.bas
dir *1.bas will list a1.bas b1.bas abcd.bas ab.bas, and the 1 after it has no effect here
dir *.* will list all files
