Wow! I'm really bad! I didn't get that about stdin at all. Never |
| 55 |
dawned on me... Stupid me... |

Thanks Florian! |

OK, using Neil's suggestion |
| 60 |
|
| 61 |
tar tfv archivername |
| 62 |
|
| 63 |
results in the first few lines: |
| 64 |
|
| 65 |
MacMini ~ # tar tvf /mnt/cdrom/evelyn.20100214.tar.bz2 |
| 66 |
drwx------ evelyn/users 0 2010-02-13 14:50 home/evelyn/ |
| 67 |
drwx------ evelyn/users 0 2008-04-11 17:33 home/evelyn/.AbiSuite/ |
| 68 |
-rw-r--r-- evelyn/users 2614 2008-07-24 01:18 |
| 69 |
home/evelyn/.AbiSuite/AbiWord.Profile |
| 70 |
drwxr-xr-x evelyn/users 0 2010-02-12 19:21 home/evelyn/.xine/ |
| 71 |
drwxr-xr-x evelyn/users 0 2007-09-19 13:36 home/evelyn/.xine/cddbcache/ |
| 72 |
-rw-r--r-- evelyn/users 761 2007-09-19 13:36 home/evelyn/.xine/cddbcache/5e0 |
| 73 |
|
| 74 |
so I tried |
| 75 |
|
| 76 |
tar xfv /mnt/cdrom/evelyn.20100214.tar.bz2 -C / |
| 77 |
|
| 78 |
and because /home/evelyn already exists the files seemed to end up in |
| 79 |
the right place. |
| 80 |

Thanks, |
