- Michael J. Mefford 1988 No. 7 (Utilities)
-
-
- Purpose: Changes the DOS date and/or time designation of a file or
- group of files either to the current system values or to user-designated
- values.
-
- Format: TOUCH filespec [/D date] [/T time]
-
- Remarks: Entered without any arguments, TOUCH displays a help screen
- showing its syntax. If given a filespec but neither of the optional switches
- (/D or /T), TOUCH updates the designated file to the current system date and
- time. Note that the standard DOS filename wild cards (* and ?) are supported,
- so TOUCH can operate on groups of files.
-
- The optional /D date switch permits entry a user-selected date in the
- customary DOS mm-dd-yy format. If desired, the hyphen delimiters may be
- replaced by forward slashes (/), and the year may be entered either in full
- form (e.g. 1988) or in abbreviated (88) form. TOUCH checks that each of the
- three fields is filled with a non-zero value, but does not check the validity
- of a date (e.g. 2/31/88). Legal DOS years are from 1980 to 2099.
-
- The optional /T time switch permits entry of a user-specified time, in
- hours:minutes:seconds. If the minutes and/or seconds parameters are omitted
- TOUCH will set them to 0. Hours should be entered in military (24-hour)
- format.
- Note: The following batch file, TEST.BAT, can be used to cause a DIR
- listing to leave the time field blank:
-
- TIME 0
- TOUCH TEST.BAT
- DIR TEST.BAT
