=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 |

58 |
|

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) |

=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 |

|
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 |
|

=item XTerm |
143 |
|
144 |
to get a login shell, start XTerm with '-ls' (~/.profile will not be executed if not) |
