I just need to edit the "rm " command such that it should move all the files / dir to a particular folder instead of deleting.

Can anyone guide me to edit the source code for rm , such that it should preserve all the deleted files / dir.

Why not use cp or mv? They already do that job (cp copies files and mv moves them).

Here is an emulated recyle bin with a few issues, which you could use as a start:

Hi everyone!

I am trying to write a bash script to emulate the rm command, I want to save all files I delete, a bit like the recycle bin in a windows OS.

The script that i got is not working properly , can any one pls guide me on this..

#!/bin/bash

function errorInvailidOpt() {

echo "rm: invalid option - $o"
echo "try \`rm -help\` for more information"
exit 0
}


function errorTooFew() {

echo "rm: too few arguments"
echo "try \`rm --help\` for more information"
}

function errorNoSuch() {

echo "rm: cannot remove $* : no such file or directory"
}


function writePro () {
echo -n "rm: remove write-protected file \`$*'?"
read ANSWER
if [ "$ANSWER" = "y" ] && [ "$FLAG_V" = "v" ] ; then
mv $OPTS $@ $TRASH 2>/dev/null

sorry for the inconvenience caused .. can any one guide me on this ...

have you looked through Gnome?
it auto puts stuff in the "trash"

hack that code , why reinvent the wheel

Hacking Gnome code? There's a job for life!

i just customize the script as below , but still its not moving files to my destination folder /tmp/trash ,

can you pls review the below script and help me out ..

1. post your code in code tags; its hard to read
2. use

set -xv

at the top to show you what's happening
3. cut the code to the bare minimum ie one option or even none to start with

4. What is that supposed to be?

Why not just make an alias:

alias rm='mv -t ~/Trash/'

add that to your .alias file or .bashrc done. if you use a alias file make sure in bashrc you have:

test -s ~/.alias && . ~/.alias || true

You should really concentrate on something simpler that you can understand. This script is obviously over the top for you, no pun intended, no one is born knowing everything, you need to learn one step at a time, just like we all did at one point. If you want to learn you should start with something simpler.

It's irrelevant if you implement this as an alias, a function or a separate script. The core of your script will be an "mv" command that will move the files to a given folder instead of rm'ing them. That's a single line, only one line of code. Find that, do it, and then you can start worrying about the rest. But building a skyscraper when you can't handle a single brick is quite ambitious.

finally i could develop a script which meeting my expectation , while deleting instead of vanishing its keeping a zipped copy of files / dir to tone specified folder.

the problem is :
i have renamed the current /bin/rm to /bin/rm_old and kept my script as /bin/rm , while am using "rm" its executing my script and working fine . but while shutting down and booting up its creating so many problems , it seams so many dependencies with original rm.


how can i rename the original rm to some other name ( /bin/rm-old ) , if am doing this whether i should mention any where so that kernel can identify the original rm is in new name /bin/rm_old

You probably shouldn't do this, purely for the reason you've described - it causes problems. Why don't you do what i92guboj or micxz suggested above?

Its regarding my MS projecct , can you pls suggest if we rename /bin/rm to /bin/rm_old what all we should do ...... also new script came to /bin/rm path also .... pls suggest ..

What you should do is put rm back to where it was and just make a the rm in YOUR environment go to your script. e.g:
alias rm='/home/jaikris/bin/rm_newscript'
Does this make sense? Hope this helps'
