batch files . . .

by Who Am I Really In reply to DOS Batch File Scripting ...

to move about in directories
use the "CD" command

CD \pathname

ie.

the easiest method of getting a path into a batch file is to first go to the location with Windows Explorer

then copy the contents of the address bar to the notepad window containing the batch file
being created

To get into the Temp folder under your User Name

use the correct path for your version of the OS
ie. on Win2K / XP it's

C:\Documents and Settings\User name\Local Settings\Temp

and to go there from the command window or a batch file it's

CD "C:\Documents and Settings\User name\Local Settings\Temp"

the opening & closing " quotes are necessary because of the spaces in the directory names

a short 3 command batch file to kill all *.tmp files in the "Temp" directory would look like this

(insert the correct user name into the path first)

CD "C:\Documents and Settings\UserName\Local Settings\Temp"

attrib -r -h -s *.tmp

del *.tmp

run that batch
while windows explorer has that folder open and you'll see the files vanish

of course it will throw 2 errors if there are no *.tmp files

you could use the
if not exist *.tmp

to check for the files first and then jump if none are there

(insert the correct user name into the path first)

ie.

@Echo off
CD "C:\Documents and Settings\UserName\Local Settings\Temp"

if not exist *.tmp goto jump
attrib -r -h -s *.tmp
del *.tmp
goto end
:jump
echo.
echo no .tmp files found
echo.
:end

You want to use the batch file command "FOR"

by neilb@uk In reply to DOS Batch File Scripting ...

Create a list of the full path to the folders in a file, each on a separate line, call it what you want. I've used zap.dat in my example.

Create a batch file with the following commmands:

FOR /F "delims=" %%i in (path_to\zap.dat) do Del /F /Q "%%i\*.txt"
FOR /F "delims=" %%i in (path_to\zap.dat) do Del /F /Q "%%i\*.log"

That should do it. Get the quotes in the correct place.
