Commodore PC 10 - Using Directories

More About Files and Directories 91
Important The wildcard abbreviation '.' refers to all files in the
directory. This feature can be both powerful and destructive when
used with MS·DOS commands. For example, the del command fol-
lowed by the wildcard abbreviation '.' deletes all files on the
default drive, regardless of filename or extension.
In general,
you should not use more than one asterisk wildcard in
a command line. For example, if you type the following command,
all the files in the directory will be listed, not just those that con-
tain
the number" 1":
dir *1*
Examples:
Suppose you want to find a certain accounting file but can't
remember its exact name. What you can do is list the directory
entries for all files named accounts in the default directory of
drive A (regardless of their filename extensions). To do this
quickly,
you could just type the following command:
dir a:account5.*
Similarly, to list the directory entries for all files with . txt exten-
sions or in a directory called reports (regardless of their file-
names) on the disk in drive B, type the following command:
dir b:\report5\*.txt
This command is useful if your text files have. txt extensions.
For example, by using the dir command with wildcard characters,
you could get a listing of all your text files - even if you don't
remember their filenames. For more information on the dir
command, refer to Chapter 3, "MS·DOS Commands."
