 Posted: Sun Nov 07, 2004 6:12 pm Post subject: I think TAR changed :( (app-arch/tar-1.14.90-r1) |
 |
|
Is it me, or is something wrong with tar? I tried this to create a bzip2 archive...
| Code: |
tar -cjf archive.tar.bz2 directory
|
... and I got this...
| Code: |
tar: Bad Option: -cvjf.
Usage: tar cmd [options] file1 ... filen
Use tar -help
and tar -xhelp
to get a list of valid cmds and options.
Use tar H=help
to get a list of valid archive header formats.
Use tar diffopts=help
to get a list of valid diff options.
|
I thought I might be typing it something wrong (it could happen, haha) but I tried using xffm4 to create an achive (gzip) and I got the same results. I checked the man page, and it seems the syntax hasn't changed. Is this just me? I'm running app-arch/tar-1.14.90-r1 |

Thanks, that worked! Tar has changed quite a bit. The verbose output is different. I wonder why they got rid of the "-". Programs like xffm4 will need to be upggraded. Oh well.  |

I noticed more wierdness. The option to stay in the same file system seems to be ignored. I had to use the --exclude option to get a similar effect. I figured that since I only wanted to backup /, that I could use the "l" options to exclude what shouldn't go into a backup, like /sys, /dev/, and my external USB HD. Here's what's mounted:
| Code: |
/dev/hda6 on / type reiserfs (rw,noatime)
none on /proc type proc (rw)
none on /sys type sysfs (rw)
none on /dev type tmpfs (rw)
none on /dev/pts type devpts (rw)
none on /proc/bus/usb type usbdevfs (rw,devgid=85,devmode=0664)
none on /dev/shm type tmpfs (rw)
/dev/usbhd on /mnt/usbhd type reiserfs (rw,noexec,nosuid,nodev)
|
So, from /, I did this...
| Code: | | tar cjplf /mnt/usbhd/backups/rootfs-20041110.tar.bz2 --wildcards --exclude "dev/*" --exclude "proc/*" --exclude "sys/*" --exclude "mnt/usbhd/*" * |
Note: I just left the "l" option for good measure. Oh, and I normally do backups from the LiveCD, so I don't encounter this problem. The LiveCD is old, so it's got an older version of tar. If that even matters. |

Ahhh! I'm going to pull my hair out  I just tried the same EXACT command (different date) to do another backup.
| Code: | tar cjplf /mnt/usbhd/backups/rootfs-20041121.tar.bz2 --wildcards --exclude "dev/*" --exclude "proc/*" --exclude "sys/*" --exclude "mnt/usbhd/*" *
|
and now I get...
| Code: |
tar: Bad Option: --wildcards.
Usage: tar cmd [options] file1 ... filen
Use tar -help
and tar -xhelp
to get a list of valid cmds and options.
Use tar H=help
to get a list of valid archive header formats.
Use tar diffopts=help
to get a list of valid diff options.
|
If I remove --wildcards it complaints about --exclude. It worked a week ago. It's the same version of tar. What the hell  |

Ok, I feel MUCH better now. Check this out...
| Code: |
$ qpkg -f /bin/tar
app-arch/tar *
$ qpkg -f /usr/bin/tar
app-arch/star *
|
Root was using /bin/tar (tar) and other users (like me) /usr/bin/tar (star). This all has to so with $PATH.
This explains why sometimes -c worked and sometimes I just had to use c. I guess one way to fix this is to remove either star or tar. I just don't know which one  |

I would remove star. I would rather have something maintained by GNU than have something that is supposed to be the fastest tar available. Most CPU time is spent in the compression phase (gzip, bzip2) anyway. |

| i have noticed this too, and i don't have 'star' emerged. with the latest version of tar (1.14.90-r1), i can't get --exclude to work. Going back to 1.14 it works fine. |
