dpath is an internal cmd.exe command on IBM OS/2 and Microsoft Windows that allows using a set of files with the
TYPE command and with input redirection as if they are in the current directory. On Windows it is undocumented and deprecated.
dpath differs from the
append command in the way it operates.
dpath informs programs what directories they should search in order to find computer files. It is then up to the applications to recognize
%DPATH%. Using the
append command on the other side, programs are able to find files without recognizing that the command is in effect.
In DOS the
append command allows programs to open data files in specified directories as if they were in the current directory. Since Windows NT this is not working as the cmd.exe introduced command processor extensions and
append become redundant. Despite this the executable was and is still available in 32-bit versions of Windows. Anyway, the command relied on
%DPATH% environment variable, which can be edited with the
dpath command. In the modern Windows installations only the
dpath command is working despite the help message still is pointing to the
DPATH pathname [;pathname] [;pathname] [;pathname]... DPATH DPATH ; pathname : drive letter and/or folder ; : the command 'DPATH ;' will clear the path
Without parameters the will display the current list of the directories.
%DPATH% environment variable also can be used.
DPATH /? will print the
append command help message.
C:\>echo hello>c:\test\in.txt C:\batch>type c:\test\in.txt hello C:\>dir /a /b C:\>set /p var=<in.txt The system cannot find the file specified. C:\>set var Environment variable var not defined C:\>dpath c:\test; C:\>set /p var=<in.txt C:\>set var var=hello
With TYPE command:
C:\>echo hello>c:\test\in.txt C:\batch>type c:\test\in.txt hello C:\>dir /a /b C:\>set /p var=<in.txt The system cannot find the file specified. C:\>type in.txt hello
