SetDate(V1.3)
NAME
SetDate - Set the DOS datestamp for files.
SYNOPSIS
1.3:
SetDate File [DATE] [TIME] [QUIET]
2.x/3.x:
SetDate File [DATE] [TIME] [QUIET] [ALL]
DESCRIPTION
SetDate changes the last modification date of a file.
This is useful with programs such as Make, or if a file
was inadvertently created when the operating system was
set to a bad date or time. The last modification date
may be viewed using the List command. As with all
programs which accept date and time information, you may
use words such as YESTERDAY, MONDAY, etc., to specify the
date.
In the 2.x/3.x version of SetDate, you can of course
use wildcard patterns to specify more than one filename.
If you supply only the filename to SetDate, the current
date will be assumed. This is probably the most common
use of a program like SetDate, and is very convenient (it
performs similarly to the Unix Touch command).
Also under 2.x/3.x SetDate uses the value of the
environment variable 'dateformat' to determine the style
of input entry it expects.
KEYWORDS
File
The name of directory or file to SetDate. Under
2.x/3.x you can use wildcards to change multiple files.
DATE
The day, month, and year you wish to change the date
to. The recognized format is: DD-MMM-YY. DD is the
two-digit number for the day. MMM is a three-letter
abbreviation for the month (eg FEB or APR). YY is the
last two digits of the year.
You may also use words like SATURDAY, YESTERDAY,
TOMORROW, etc. Saturday, Sunday, Monday, and the rest of
the days of the week can be used as flags. The system
will evaluate the day then advance the system date to
match the specified day of the week. So, if it is Monday
and you specify Thursday, the system clock will advance
by three days.
If the date is not specified then the file is set to
the current system date and time.
Time
You can set the time along with the date with the use
of this optional keyword. The recognized format is
HH:MM:SS, for hours, minutes, and seconds respectfully.
Hours are recognized in a 24-hour format (aka Military
Time) where 1:00pm is represented by 1300 hours. If you
leave out minutes and/or seconds they are defaulted to
00. If you don't include this keyword then the time-stamp
on the file is defaulted to 00:00:00.
EXAMPLE
1. To set the date to January 1st, 1988 to 12:15 for
the file 'myfile'.
SETDATE myfile 01-jan-88 12:15
2. To give the file 'foo' yesterday's date:
SETDATE foo YESTERDAY
3. To set all files ending in .o to the current
date.
SETDATE *.o
