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...

shells

shells(4)							   File Formats 							 shells(4)

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The  following  default	shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh,
       /bin/tcsh,  /bin/zsh,  /sbin/jsh,  /sbin/sh,  /usr/bin/bash,  /usr/bin/csh,  /usr/bin/jsh,  /usr/bin/ksh,  /usr/bin/pfcsh,  /usr/bin/pfksh,
       /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh. Note that /etc/shells overrides the default list.

       Invalid shells in /etc/shells may cause unexpected behavior (such as being unable to log in by way of ftp(1)).

FILES

       /etc/shells	       lists shells on system
