Accidently deleted /usr contents.

Hi

I have the following code which was supposed to clean up a directory when the number of files in that directory exeeded 2.The code is given below.

Code:
 
#!/usr/bin/ksh
dir_num=`/usr/bin/find /var/.audit -type d | /usr/bin/wc -l`
if [ $dir_num -gt 2 ]
then
 oldest_file=`/usr/bin/ls -1t | /usr/bin/tail -1`
 /usr/bin/rm -rf $oldest_file
fi

When executed the above code something bad happened.Apparantly most of my files in
Code:
/usr

directory got deleted.Can anyone tell me how it happened?

I have the modified code:
Code:
 
 
#!/usr/bin/ksh
dir_num=`/usr/bin/find /var/.audit -type d | /usr/bin/wc -l`
if [ $dir_num -gt 2 ]
then
 oldest_file=`/usr/bin/ls -1t /var/.audit/ | /usr/bin/tail -1`
 /usr/bin/rm -rf /var/.audit/$oldest_file
fi

Is there any way to recover those file?

Thanks in advance...

NAME
times - shell built-in function to report time usages of the current shell SYNOPSIS
sh times ksh times DESCRIPTION
sh Print the accumulated user and system times for processes run from the shell. ksh Print the accumulated user and system times for the shell and for processes run from the shell. On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways: 1. Variable assignment lists preceding the command remain in effect when the command completes. 2. I/O redirections are processed after variable assignments. 3. Errors cause a script that contains them to abort. 4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari- able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not performed. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ SEE ALSO
