linux下的小工具--trash-rm
在linux下用rm删除文件，一不小心就会干坏事……譬如不小心把系统文件删光了，所以萌生一个想法，能不能把rm删除动作绑定到垃圾箱，这样万一删错了还能找回来。
上网搜了一下，发现已经有人干过这事，转载过来供大家参考。

1. Install trash-cliThis package provides a command line interface trashcan utility compliant with the FreeDesktop.org Trash Specification. It remembers the name, original path, deletion date, and permissions of each trashed file.In Ubuntu, simply run this command:
sudo apt-get install trash-cli
2. Set up the script
In Ubuntu enter this in a terminal:
sudo gedit /usr/local/bin/trash-rm
And paste this in the newly opened file, then save it:
1
#
!
/
bin
/
bash
2
#
command
name: trash-rm
3
shopt -s extglob
4
recursive
=
1
5
declare -a
cmd
6
((
i
=
0
))
7
for
f in
"
$@
"
8
do
9
case
"
$f
"
in
10
(
-*
(
[fiIv]
)
r*
(
[fiIv]
)
|-*
(
[fiIv]
)
R*
(
[fiIv]
))
11
tmp
=
"
${f//[rR]/}
"
12
if
[ -n
"
$tmp
"
]
13
then
14
#
echo
"
\$tmp == $tmp
"
15
cmd
[
$
i]
=
"
$tmp
"
16
((
i
++))
17
fi
18
recursive
=
0
;;
19
(
--recursive
)
recursive
=
0
;;
20
(
*
)
21
if
[
$
recursive !
=
0
-a -d
"
$f
"
]
22
then
23
echo
"
skipping directory: $f
"
24
continue
25
else
26
cmd
[
$
i]
=
"
$f
"
27
((
i
++))
28
fi
;;
29
esac
30
done
31
trash
"
${cmd[@]}
"
Then make it executable by opening a terminal and running this:
sudo chmod +x /usr/local/bin/trash-rm
3. Create an alias for "rm" to use "trash-rm"
In Ubuntu, run this in a terminal:
gedit ~/.bashrc
and enter this at the end of the file:
alias rm="trash-rm"
and save it.
Then reload bashrc by running the following command in a terminal:
bash
That's it! Now try it out by deleting files the way you always do, using "rm" and "rm -r".
Final trash-cli tips
Since you've installed the trash-cli utility, now you can use the following commands for manipulating the trash from the command line (the names are self explanatory):
empty-trash
list-trash
restore-trash
Update: to get this to work for "sudo rm" as well, copy
wilo108's sudo wrapper in your ~/.bashrc file. Without it, this will not work when "rm" is used with "sudo"!
