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.

NAME

     intro -- introduction to general commands (tools and utilities)

DESCRIPTION

     Section one of the manual contains most of the commands which comprise the BSD user environment.  Some of the commands included in section
     one are text editors, command shell interpreters, searching and sorting tools, file manipulation commands, system status commands, remote
     file copy commands, mail commands, compilers and compiler tools, formatted output tools, and line printer commands.

     All commands set a status value upon exit which may be tested to see if the command completed normally.  Traditionally, the value 0 signifies
     successful completion of the command, while a value >0 indicates an error.  Some commands attempt to describe the nature of the failure by
     using exit codes as defined in sysexits(3), while others simply set the status to an arbitrary value >0 (typically 1).
