=head3 Description |
| 33 |
|
| 34 |
All stuff here is mainly copied from the libtrash doc. |
| 35 |
|
| 36 |
libtrash is a shared library which, when preloaded, implements a trash can under GNU/Linux. |
| 37 |
This way, your mistakes (at least those of the "rm -rf dir /" class :-)) will no longer cause |
| 38 |
the loss of a week's work or your system's binaries. |
| 39 |
|

|
| 41 |
=head4 install libtrash |
| 42 |
|
| 43 |
apt-get install libtrash |
| 44 |
|
| 45 |
|
| 46 |
or for those of you that aren't running Debian GNU/Linux: |
| 47 |
|
| 48 |
wget http://www.m-arriaga.net/software/libtrash/libtrash-latest.tgz |
| 49 |
tar xzf libtrash-latest.tgz |
| 50 |
cd libtrash-1.7/ |
| 51 |
|
| 52 |
edit Makefile for common settings |
| 53 |
|
| 54 |
make install (as root) |
| 55 |
|
| 56 |
|
| 57 |
=head4 test |
| 58 |
|
| 59 |
export LD_PRELOAD=/usr/lib/libtrash/libtrash.so |
| 60 |
rm -r <some_test_file> |
| 61 |
|
| 62 |
|
| 63 |
=head4 enable libtrash at login |
| 64 |
|
| 65 |
Include this in your ~/.bash_profile(or for system-wide usage in /etc/profile) |
| 66 |
to enable libtrash every time you log in (or otherwise start a login shell) |

|
| 92 |
- READ /etc/libtrash.conf !! |
| 93 |
- overwrite default values by setting up a ~/.libtrash for each user: |

=head4 use 'cleanTrash' for cleaning Trash via cronjob |
| 108 |
|
| 109 |
- gunzip & copy '/usr/share/doc/libtrash/examples/cleanTrash/ct2.pl.gz' |
| 110 |
to '/usr/local/bin/cleanTrash' e.g: |
| 111 |
|
| 112 |
'zcat /usr/share/doc/libtrash/examples/cleanTrash/ct2.pl.gz > /usr/local/bin/cleanTrash' |
| 113 |
|
| 114 |
|
| 115 |
- edit '/usr/local/bin/cleanTrash' for local configuration |
| 116 |
|
| 117 |
|
| 118 |
|
| 119 |
=head5 insert cronjob for root |
| 120 |
|
| 121 |
- crontab -e (as root) |
| 122 |
- insert: 3,13,23,33,43,53 * * * * root /usr/local/bin/cleanTrash |

=item Gerneral |
| 132 |
|
| 133 |
READ /etc/libtrash.conf !! |
| 134 |
If libtrash.so is global enabled via /etc/profile, a DEFAULT or WRONG ~/.libtrash configuration would |
| 135 |
causes gdm, root writes(if root writes are also protected by lintrash), kde etc. stops working !! |
| 136 |
|
| 137 |
solution to disable libtrash in enviroment immediately: |
| 138 |
- export LD_PRELOAD="" |
| 139 |
|
| 140 |
|
| 141 |
|
| 142 |
=item XTerm |
| 143 |
|
| 144 |
to get a login shell, start XTerm with '-ls' (~/.profile will not be executed if not) |
