| Post subject: | tar question - backing up a dir and ignore symlinks? |
Any tar gurus out there? I've been using tar to backup my system and I'm wondering what switch I need to through into my line to have tar IGNORE my symlinks. Anyone? Here is the syntax I've been using, but again, it will follow any symlinks which I do NOT want 
Thanks! Code: tar zcvfp backup-system.tar.gz /etc /boot /root /home

Not sure what you are really after here, as I believe tar normally doesn't follow symlinks, but see the -h option here if you are trying to backup the files/directories your symlinks are pointing to and not the actual link. If you are trying to ignore symlinks altogether (as in no reference to them or the files/directories they point to whatsoever), you may want to use find with the -H or multiple -t, -e -d options in conjunction with cpio. man find for more information. |

I think the -h switch will do the trick. Thanks. BTW, the output of a simple, 'man tar' wasn't that useful. There is a great online manual for tar over at gno.org. MUCH more descriptive. |

Actually, the -h will follow symlinks, which I don't think is what you want. Without the -h, the symlinks will be saved, not the files or dir they point to. When you extract the files, are you sure it isn't a symlink that is extracted? It will look exactly like the original. Example: Code: allen@violet:~$ ls -al etc/lircd.conf
lrwxrwxrwx 1 allen allen 20 Jan 23 09:09 etc/lircd.conf -> /etc/lirc/lircd.conf allen@violet:~$ To get it to completely ignore symlinks will probably require the use of "find". |
