How to modify rm command ?
 

Dear Friends,

When we execute rm command then the target files or directories are permanently removed from our computer.

Is there any way my which when we execute rm command then the files or directories moved to Trash.

please help me, its very important for me.

Thanks in advance

Hi,

You can create a script rm.sh (and put it for example in /usr/bin):
and use alias to alias rm to the script:

Following the suggestion by bathory, you may want to be able to move more files at once (for example when using wildcards). In this case better to use $@ to catch all the command line arguments:
Moreover, since emptying trash is something that many users forget about, you may want to add a check on the Trash size and/or on the filesystem percent usage. Eventually the user may be warned and receive advice to empty the trash bin. Finally, take in mind that files with the same name will be overwritten, so that older versions will be definitively lost.

Sometimes that's not a good idea though since there are some system scripts like boot scripts that may also use the rm command to permanently delete files like temporary files. It's probably better to create another similar script utility with different filename like /usr/bin/trash.

This question turns up once in a while, was talked about recently, so searching LQ will yield results. To keep you from reinventing the wheel see http://www.linuxquestions.org/questi...9/#post3987860.

Agreed, I would not change the behaviour of a fundamental command like rm in such a way. Creating a new 'trash' command would be better.

Sure, but putting an alias in his .bash_profile does not affect how rm works in boot scripts and system scripts in general.

thanks for your questions, but I am quite confuse.
Please provide a viable solution to do this.

sorry for spelling mistake

Solution is in posts #2 and #3. Put the alias in your .bash_profile

1. Create the command /usr/bin/rm.sh as follow (as root):
2. Append that command to your .bash_profile (as normal user)

Well how bout the other scripts that will run after .bash_profile is loaded? e.g. co-shellscripts run by user apps?

Also I suggest that it's better to have functions instead of aliases since sometimes aliases do not work the way they should be. Perhaps at least on the earlier versions of bash?

Edit: Oh I forgot. Yeah right. Functions and aliases are not exported so this can be safely done.

Not only that, but .bash_profile is not executed by scripts run by user apps. This is the difference between .bash_profile and .barhrc. .bash_profile is only executed in interactive mode.

No I did not meant that scripts will call .bash_profile, what I meant is what will be in the shell environment and shared to subscripts after it is called;.. but it's ok since it won't be exported or shared anyway.

Edit: Or maybe you meant a different angle.. well ok.

Actually we don't even have to think about it since sometimes .bashrc is not also called. What really mattered was the effect after a new virtual version of rm is created.
