Don, The functionality you need is "/dev/null".
Indeed, the function of /dev/zero is to provide a
file which you can read indefinitely. You should use
it like this :
dd if=/dev/zero of=<whatever> bs=1024 count=number_of_blocks

Jurgen

Subject: cp /dev/zero filename creates large files
Classification:
Hi
I carried out the following sequence of commands
$ for i in `cat /tmp/d`; do if [ -f $i.idx ]; then ls -l ${i}*; fi; done
-rw-r--r-- 1 don None 0 Jun 17 1998 dtaq
-rw-r--r-- 1 don None 3072 Jun 17 1998 dtaq.idx
$ cp /dev/zero dtaq.idx
The cp appeared to be hanging and the disc was rattling away, so in
another window I typed in
$ ls -l dtaq*
-rw-r--r-- 1 don None 0 Jun 17 1998 dtaq
-rw-r--r-- 1 don None 65307648 Jun 17 1998 dtaq.idx
and you can see that the reported size of the target of the 'cp
/dev/zero' has grown to a considerable size in a short time.
Can anyone else reproduce this?
Attaching cygcheck.log
Cheers
