If you use the -d (preserve links), -p (preserve file attributes) and -R (copy directories recursively) you should have no problems with cp. The short cut for all three parameters is -a.

I'm not sure about that. If I got it right plain cp will copy the file, it will not create a symobolic link. So your symbolic link structure will be ruined. tar on the other hand preserves it. Sasha.

One way to do this is to use tar: ( cd /old/location ; tar cf - . ) | ( cd /new/location ; tar xpf - ) > What is the command to format (initialise ?) a partition ? To create a file system use the appropriate command for the files system type, e.g. mke2fs for the "second extended files system" that is common in Linux. Beware: you will be erasing any data that currently exists in the partition! Use the mount command to mount the new partition and add an entry to /etc/fstab to automatically mount it at boot time. - MikeT -- Michael E. Touloumtzis <[EMAIL PROTECTED]>

Symbolic links are just names of files. If the path of the destination stays the same (/usr is still /usr, even though the mount table is different) you shouldn't have problems just using cp.

Re: Moving partition
I already have different partitions for / , /var , /home , /usr. In fact, my problem is : How do I move files from an old parttion to a new one while ensure all links (and things like that) are kept ? What is the command to format (initialise ?) a partition ?

Re: Moving partition
> >You could also make a new partition and mount it as /home, or /usr, or >some such. > Glad to hear that suggestion as that is precisely what I would do! Actually, I never put it all on one partition anyway. Old habits are hard to break. I like to get /var and /home OFF the root if possible, and generally use a single separate partition for /usr also. That also makes it easier to take advantage of multiple disks and the 2nd IDE controller on most m'bds these days. I typically put the 1st disk along with the CD (if ATAPI) and a 2nd disk, even if its small, on the 2nd IDE port. Put swap and /var on it, or even /home. Another advantage of this is, when you decide to try another distribution you just use /home with it, and swap, plus, you often have a partition or two around that comes in handy when it comes time to resize one, or move stuff around, etc. You'll find the system performance will be a little better too, 'cause it'll be able to take better advantage of the capabilities by keeping the I/O going on two disks instead of all of it on one, plus the additional controller channel.

Re: moving partition boundries???
I used to have Partition Magic 3.0x installed back in the days when I was using a 2GB disk and it was definately one of my favorite programs. There was a posting on Slashdot awhile back that Partition Magic 4.0, when released, will fully support Linux partitions with ext2 formating, and IIRC this part would be available for free download. Definately a good thing I remember 3.0x would at least recognise ext2 partitions but you couldn't move, resize, play with cluster sizes (don't know why you'd want to do this with ext2 anyways though), etc... none of the cool things PM lets you do with fat/vfat/fat32/hpfs/ntfs partitions. Another cool thing about PM is that you don't need to manually defrag a partition before resizing it. Quite an impressive piece of software Powerquest managed to pull off Of course, now that I have my 9.1GB disk I don't really need it anymore since at any given time it seems I have at least 2GB of unpartitioned space and I keep my disk _very_ split so if I want to move ext2 partitions around I can use the 2GB+ for temporary space to store the files from an Ext partition while preparing where the files are to go. The ability to change the boundaries of the extended partition sure is something I miss though when I had PM 3.0x. This operation never took more than a fraction of a second (unlike, say, resizing a partition and changing the cluster size at the same time, which would take _FOREVER_, understandably). Since the extended partition resize only takes a fraction of a second and the extended partition itself has no formatting of any kind to complicate matters then I suppose that fundamentally all that defines an extended partition may just be a few bytes of data in the MBR to set boundaries, so if that is true then AFAIK it couldn't be modifying more than 512 bytes of data, which leads one to wonder if a free extended partition resizer could be developed without taking too much time/effort.
