dd if=/dev/zero of=x seek=newsize bs=1 count=0
I just noticed you can use count=0 to avoid the extra byte.
So, this seems to be the easiest way to truncate a file in Linux.

Well, this is silly. If you use dd to truncate a file this way you
lose the trailing byte :)
I really want to know : Is there another way to truncate a file in Linux?
This would be a silly way to avoid wasting a byte to truncate a file
to have 2 bytes with dd.

Well, let's see an example. Disclaimer : You're on your own.
~$ dd if=/dev/zero of=test.fs bs=1M count=100
100+0 records in
100+0 records out
104857600 bytes transferred in 0.162605 seconds (644
How to resize a ext3 root_fs ?
e2fsck -j ext3 filename
dd if=/dev/zero of=filename bs=1 count=1 seek=newsize conv=notrunc
resize2fs -p filename
e2fsck -j ext3 filename
this works ?
