Top Forums UNIX for Advanced & Expert Users How to prevent Accidents 'rm -rf *'? Post 302904218 by deepakwins on Tuesday 3rd of June 2014 12:15:29 AM

How to prevent Accidents 'rm -rf *'?

When invoking unix commands from other third party tools (IBM ETL), we run the rm / mv commands with the folder as argument been passed. Eg

Code:
rm -rf {folder}/*

when the parameter {folder} did not pass rightly or becomes blank, the command becomes dangerous to execute
Code:
rm -rf /*

How to prevent the disaster?

I seen some suggestions to add alias as alias
PHP Code:
rm='rm -i' 
But this wont work all the time, as we cannot make the command interactive when running from a tool.

Situation becomes worse, when the command is execute via super user.

Please throw some light.

Thanks,
Deepak

rmf(1)							      General Commands Manual							    rmf(1)

NAME
rmf - remove folder (only available within the message handling system, mh) SYNOPSIS
rmf [+folder] [-help] [-[no]interactive] OPTIONS
Prints a list of the valid options to this command. Asks for confirmation before deleting a folder. By default, rmf deletes a folder and its messages without asking for confirmation. If you specify the -interactive option, rmf asks if you are sure before deleting the folder. You are advised to use this option, since when rmf deletes a folder its contents are lost irretrievably. DESCRIPTION
The rmf command removes all of the messages within the current folder, and then removes the folder itself. If there are any files within the folder which are not part of MH, they are not removed, and an error message is displayed. You can specify a folder other than the current folder by using the +folder argument. If you do not specify a folder, and rmf cannot find the current folder,rmf asks you whether you want to delete +inbox instead. If the current folder is removed, it makes +inbox current. Note that the rmf command irreversibly deletes messages that do not have other links, so use it with caution. If the folder being removed is a sub-folder, the parent folder becomes the new current folder, and rmf tells you that this has happened. This provides an easy mechanism for selecting a set of messages, operating on the list, then removing the list and returning to the current folder from which the list was extracted. Using rmf to delete a read-only folder deletes the private sequence and current message information from the file, without affecting the folder itself. If you have sub-folders within a folder, you must delete all the sub-folders before you can delete the folder itself. PROFILE COMPONENTS
Path: To determine the user's Mail directory EXAMPLES
This example shows how rmf asks for confirmation when the -interactive option is used: % rmf -interactive +test Remove folder "test"? y FILES
