UNIX Recycle Bin - restore function
Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!
1. The problem statement, all variables and given/known data:
A set of Linux shell scripts is required to allow users to ‘remove' files without them really disappearing until the ‘dustbin' is emptied. The three shell scripts required are :-
del <filename> - This script should move the file called <filename> (a full or relative pathname) to the
dustbin directory.
trash [-a] - This script should remove the contents of the dustbin directory.
If the -a option is not used, the script should print the filenames in the dustbin one by one and ask the
user for confirmation that they should be deleted.
Otherwise, If the -a option is used, the script should simply remove ALL files from the dustbin.
restore [-n] <filename> - This script should move the file called <filename> (a full or relative pathname)
back to its original directory.
If the -n option is used, the script should allow the file to be moved to a directory nominated by the user.
Help:
I need help with the restore function.
How can I save the original path of the file and then after deletion move it back? (bash code would help)
Any relevant ideas on how to do this can help me very much.
Thanks!
2. Relevant commands, code, scripts, algorithms:
bash code
using Puppy Linux OS
I used a dustbin directory to keep my deleted files
3. The attempts at a solution (include all code and scripts):
To get the path of the file I used this:
ABS_PATH=$(cd $(dirname ${1});pwd)
4. Complete Name of School (University), City (State), Country, Name of Professor, and Course Number (Link to Course):
Edinburgh Napier University , Edinburgh , UK , Dr Alistair Armitage , CSN08101 Systems and Services
Note: Without school/professor/course information, you will be banned if you post here! You must complete the entire template (not just parts of it).

debconf-mergetemplate
DEBCONF-MERGETEMPLATE(1) Debconf DEBCONF-MERGETEMPLATE(1)
NAME
debconf-mergetemplate - merge together multiple debconf template files
SYNOPSIS
debconf-mergetemplate [options] [templates.ll ...] templates
DESCRIPTION
Note: This utility is deprecated. You should switch to using po-debconf's po2debconf program.
This program is useful if you have multiple debconf templates files which you want to merge together into one big file. All the specified
files will be read in, merged, and output to standard output.
This can be especially useful if you are dealing with translated template files. In this case, you might have your main template file, plus
several other files provided by the translators. These files will have translated fields in them, and maybe the translators left in the
english versions of the fields they translated, for their reference.
So, you want to merge together all the translated templates files with your main templates file. Any fields that are unique to the
translated files need to be added in to the correct templates, but any fields they have in common should be superseded by the fields in the
main file (which might be more up-to-date).
This program handles that case properly, just list each of the translated templates files, and then your main templates file last.
OPTIONS
--outdated
Merge in even outdated translations. The default is to drop them with a warning message.
--drop-old-templates
If a translation has an entire template that is not in the master file (and thus is probably an old template), drop that entire
template.
