=head2 Implements a "trash can" under GNU/Linux with 'libtrash' |
| 18 |

=head3 Description |
| 21 |
|
| 22 |
All stuff here is mainly copied from the libtrash doc. |
| 23 |
|
| 24 |
libtrash is a shared library which, when preloaded, implements a trash can under GNU/Linux. |
| 25 |
This way, your mistakes (at least those of the "rm -rf dir /" class :-)) will no longer cause |
| 26 |
the loss of a week's work or your system's binaries. |
| 27 |
|
| 28 |
|

=head4 install libtrash |
| 30 |
|
| 31 |
apt-get install libtrash |
| 32 |
|
| 33 |
|
| 34 |
or for those of you that aren't running Debian GNU/Linux: |
| 35 |
|
| 36 |
wget http://www.m-arriaga.net/software/libtrash/libtrash-latest.tgz |
| 37 |
tar xzf libtrash-latest.tgz |
| 38 |
cd libtrash-1.7/ |
| 39 |
|
| 40 |
edit Makefile for common settings |
| 41 |
|
| 42 |
make install (as root) |
| 43 |
|
| 44 |
|
| 45 |
=head4 test |
| 46 |
|
| 47 |
export LD_PRELOAD=/usr/lib/libtrash/libtrash.so |
| 48 |
rm -r <some_test_file> |
| 49 |
|
| 50 |
|
| 51 |
=head4 enable libtrash at login |
| 52 |
|
| 53 |
Include this in your ~/.bash_profile(or for system-wide usage in /etc/profile) |
| 54 |
to enable libtrash every time you log in (or otherwise start a login shell) |
| 55 |

- READ /etc/libtrash.conf !! |
| 81 |
- overwrite default values by setting up a ~/.libtrash for each user: |

=head4 use 'cleanTrash' for cleaning Trash via cronjob |
| 96 |
|
| 97 |
- gunzip & copy '/usr/share/doc/libtrash/examples/cleanTrash/ct2.pl.gz' |
| 98 |
to '/usr/local/bin/cleanTrash' e.g: |
| 99 |
|
| 100 |
'zcat /usr/share/doc/libtrash/examples/cleanTrash/ct2.pl.gz > /usr/local/bin/cleanTrash' |
| 101 |
|
| 102 |
|
| 103 |
- edit '/usr/local/bin/cleanTrash' for local configuration |
| 104 |
|
| 105 |
|
| 106 |
|
| 107 |
=head5 insert cronjob for root |
| 108 |
|
| 109 |
- crontab -e (as root) |
| 110 |
- insert: 3,13,23,33,43,53 * * * * root /usr/local/bin/cleanTrash |

|
| 121 |
READ /etc/libtrash.conf !! |
| 122 |
If libtrash.so is global enabled via /etc/profile, a DEFAULT or WRONG ~/.libtrash configuration would |
| 123 |
causes gdm, root writes(if root writes are also protected by lintrash), kde etc. stops working !! |
| 124 |
|
| 125 |
solution to disable libtrash in enviroment immediately: |
| 126 |
- export LD_PRELOAD="" |
| 127 |
|
| 128 |
|
| 129 |
|
| 130 |
=item XTerm |
| 131 |
|
| 132 |
to get a login shell, start XTerm with '-ls' (~/.profile will not be executed if not) |
