# doschk(1)

checks filenames for SYSV and DOS compatibility

## NAME

doschk - checks filenames for SYSV and DOS compatibility

## SYNOPSIS

**doschk** filename ...

## DESCRIPTION

This program is intended as a utility to help software developers ensure that their source file names are distinguishable on MS-DOS and 14-character SYSV platforms.  To perform this task, doschk reads a list of filenames and produces a report of all the conflicts that would arise if the files were transferred to a MS-DOS or SYSV platform.

To use this program, you must feed it a list of filenames in this format:

	dir

	dir/file1.ext

	dir/file2.exe

	dir/dir2

	dir/dir2/file3.ext

If the list does not include the directory-only lines (like dir/dir2) then their names will not be checked for uniqueness, else they will be.  Typical uses of this program are like these:

	find . -print \| doschk

	tar tf file.tar \| doschk

If this program produces no output, then all your files are MS-DOS compatible.  Any output messages are designed to be self-explanatory and indicate cases where the files will not transfer to MS-DOS without problems.
