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. ~$ echo 12345 > x ~$ dd if=x skip=1 bs=1 count=1 > t ~$ dd if=t seek=1 of=x count=1 bs=1 ~$ cat x 12 Regards, Nelson.- On Tue, 15 Mar 2005 12:48:41 -0500, Nelson Castillo <[EMAIL PROTECTED]> wrote: > On Tue, 15 Mar 2005 18:14:06 +0100, Blaisorblade <[EMAIL PROTECTED]> wrote: > > On Tuesday 15 March 2005 16:17, itamar wrote: > > > 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 ? > > IIRC it works well, I just don't remember whether conv=notrunc is needed... > > Hey!
