JSI Tip 0494 - How to parse a batch parameter.
April 14, 1998
When you invoke a batch file with a parameter (%1), you are able to parse it to extract meaningfull information (if Command Extension are enabled). See the following examples:
Parameter | D e s c r i p t i o n |
---|---|
%1 | The normal parameter. |
%~f1 | expands %1 to a fully qualified path name. |
%~d1 | expands %1 to a drive letter only. |
%~p1 | expands %1 to a path only. |
%~n1 | expands %1 to a file name only (prefix) |
%~x1 | expands %1 to a file extension only. |
%~s1 | changes the meaning of n and x options to reference the short name. |
%~z1 | Returns the size of the file, if %1 is a file. |
%~a1 | Returns the attributes of the %1 object. |
%~t1 | Returns the date and time that a file was modified, if %1 is a file. |
You can use some of these modifiers in combination:
Parameter | D e s c r i p t i o n |
---|---|
%~dp1 | expands %1 to a drive letter and path only. |
%~nx1 | expands %1 to a file name and extension only. |
See tips 523, 273, and 3579.
