Hey, I'm looking for a way to use a batch file to create directories based on the current date.... this is an extention of a batch file that creates a nightly backup of a friend's files.

i tried:
Code: 
mkdir %date$

however the %date% command returns slashes (ex: 1/29/2003) that will not work with mkdir.

I need some way to tokenize the information returned form %date% and replace the slashes with dashes (ex: 1/29/2003 becomes 1-29-2003)... or just use another commadn that returns usable data.

I want to keep the existing batch file cause it's what's currently in place, easy to modify, single file solution, and easy to read/understand.


if i cant end up doing all this with a batch file i will probably try to make a c++ .exe file that will take the input from %date% and format it correctly... err... actaully...possibly even make it do must of the grunt work and just have the .bat be a "front-end". But i would like to keep this a single file solution if possible... anybody got some ideas for me?



Here's the current batch file... keep in mind that I am giving this to a computer user with limited DOS exposure who will need to make changes occasionally.
Code:

I have something at the office that should do the trick, I think. It's something I hacked from something else to create backups named for the day they were created, but I think it could be hacked once again to do what you want. I'll take a look at it in the morning.

Dunno about other Windows versions, but under XP Pro:

mkdir %date:~4,2%-%date:~7,2%-%date:~-4%

BTW, Windows XP defaults the %date% var to dow mm-dd-yyyy (dow=Day of Week; Wed for today).

well, i decided to be a wuss and get a .exe to do the job for me.... I am testing this on winXp... but it should be compatible with win2k and XP at the least so that means cmd.exe.

Fushigi... on my winXP SP1 system
%date% returns "01/29/2003" ... i dont know how yours does any different... is your date format in regional settings different from mine perhaps?

I'll try the other thing you listed.... it doesnt work correctly now, but maybe i can mod it.

Merc:
i tried using FIND... all i could do with it was to strip out entire lines of output that conatined a search character... so if a line contained a "/" the entire line would be gone... instead of just the "/"... maybe it was too late at night for me but i dont know if FIND can do what i want.

yup fushigi, regional setttings were the discrepency between my sytem and yours..... that's bad.... because my system is set to English(Canadian) and is customized so measurement and time/date format appear the same as English (US)....

you are set to English(US) which is unfortunately diff from my customized canadian

And the person who is using this program is on a Chinese version of windows 2k....

maybe i should just stick with the .exe i found...



here's a copy of my code if you're intersted

Dunno about other Windows versions, but under XP Pro:

mkdir %date:~4,2%-%date:~7,2%-%date:~-4%

BTW, Windows XP defaults the %date% var to dow mm-dd-yyyy (dow=Day of Week; Wed for today).

I have never seen the system variables used that way (although I understand it now). Do you have a link to a resource that dicussed its use?

From the DOS, er, command prompt, enter HELP SET and take a read. I didn't know it existed either before this morning.

yup fushigi, regional setttings were the discrepency between my sytem and yours..... that's bad.... because my system is set to English(Canadian) and is customized so measurement and time/date format appear the same as English (US)....

you are set to English(US) which is unfortunately diff from my customized canadian

And the person who is using this program is on a Chinese version of windows 2k....

It also works on W2K but not on W98.

How about this:

mkdir %date%
if errorlevel == 1 mkdir %date:~-10,2%-%date:~-7,2%-%date:~-4%

This is the funtional equivalent of Fushigi's code:
Code: 
for /F "tokens=2-4 delims=/ " %I in ("%date%") do @md %I-%J-%K

As is this:
Code: 
for /F "tokens=2-4 delims=/ " %I in ('date /t') do @md %I-%J-%K

Maybe the second is more universal.

I decided to go with the FDATE.exe file because depending on the regional settings the Day of week may or may not be displayed... the month and day posistions might be switched... there may or may not be leading zeros... there may be 2 or 4 number years... and the delimiters might go from dashes to slashes.... the FDATE.exe works in DOS, win9x, and winNT based OS's with the same usable output.
