Top Forums UNIX for Advanced & Expert Users How to prevent Accidents 'rm -rf *'? Post 302904305 by deepakwins on Tuesday 3rd of June 2014 11:57:24 AM

Don / Cero, Thanks for your Reply!!!

I was intended to say as what Cero interpreted.
The tool that I use, would invoke a "rm" or "/usr/bin/rm" commands.
Operands will be passed to the 'rm' utility, with the optional arguments of -r / -rf / -f etc as parameters.
Eg for the parameters:

Code:
/usr/bin/rm -rf #folder#/#filepatter#*.csv

rm -f #folder#/#filepatter#*

/bin/rm -rf #folder#/*

cd #directory# ; touch #file(s)# ; rm -rf #file(s)#

During any abnormality, there are chances for the tool to send parameters like #folder# or #file# as empty value.
And we know the impact of it.

I was infact trying the options this morning, similar to what cero was describing in.
I created the alias, and it would work in unix terminal, but not in the tool. Not sure, If i need to bounce the tool to refresh the change in .profile.
So with the help of admins, i tried to create the soft link for the rm command.
/usr/bin
Code:
rm -> /home/dsadm/rm_chck.ksh

And it seems to work for my testing.

And thinking to add more conditions to capture in the script as Don mentioned.

Atleast this way, we can avoid the possibilities of known issues that we far. Hope this would be a right way to proceed.

RMM(1)								     [nmh-1.5]								    RMM(1)

NAME
rmm - remove messages SYNOPSIS
rmm [+folder] [msgs] [-unlink | -nounlink] [-version] [-help] DESCRIPTION
By default, rmm will remove the specified messages by renaming each of the message files with a site-dependent prefix (usually a comma). Such files will then need to be removed in some manner after a certain amount of time. Many sites arrange for cron to remove these files once a day, so check with your system administrator. Alternately, if you wish for rmm to really remove the files representing these messages, you can use the -unlink switch. But messages removed by this method cannot be later recovered. If you prefer a more sophisticated method of `removing' messages, you can define the rmmproc profile component. For example, you can add a profile component such as rmmproc: /home/foouser/bin/rmm_msgs then instead of simply renaming the message file, rmm will call the named program or script to handle the files that represent the messages to be deleted. Some users of csh prefer the following: alias rmm 'refile +d' where folder `+d' is a folder for deleted messages, and alias mexp 'rm `mhpath +d all`' is used to "expunge" deleted messages. The current message is not changed by rmm, so a next will advance to the next message in the folder as expected. FILES
$HOME/.mh_profile The user profile PROFILE COMPONENTS
Path: To determine the user's nmh directory Current-Folder: To find the default current folder rmmproc: Program to delete the message SEE ALSO
refile(1), rmf(1) DEFAULTS
`+folder' defaults to the current folder `msgs' defaults to cur `-nounlink' CONTEXT
If a folder is given, it will become the current folder. BUGS
Since refile uses your rmmproc to delete the message, the rmmproc must NOT call refile without specifying -normmproc, or you will create an infinte loop. MH.6.8 11 June 2012 RMM(1)
