dosname

display the short name (8.3) or long name equivalent of file names 

Command

SYNOPSIS

dosname [-q] -l | -s | -u filename...

DESCRIPTION

dosname displays either the short name (8.3) or long name equivalents of the specified filenames based on whether you specify -l or -s. If you do not specify any filenames, dosname reads the standard input, assuming each line to be a file name.

As a side effect, you can use dosname to determine if a given path is valid simply by checking if dosname completes successfully when passed the path in question.

-q

EXAMPLE

To display the short name (8.3) equivalent of all files in the current directory tree, use 

find . | dosname -s
