Script to check if files exits
Hi

In live system core files are generating frequently. around 10 core files in 30 mins in root file system. which is eating my space very much
below is core file
Code:
 
 core.56539
core.78886
core.12302
core.80554
core.20147

I am trying to write a script which should move this file to another path till i get the solution but it is not working.

Code:
 
 #!/bin/bash
cd /root
if [ -s *core* ]
then
    mv *cor* /tmp/scriptor
else
        echo "No core file" >>coer.log
fi

below is the error which i am getting
Code:
 
 ./checkcore.sh
./checkcore.sh: line 3: [: too many arguments

regards,
scriptor

crashinfo

CRASHINFO(8)						    BSD System Manager's Manual 					      CRASHINFO(8)

NAME

     crashinfo -- analyze a core dump of the operating system

SYNOPSIS

     crashinfo [-d crashdir] [-n dumpnr] [-k kernel] [core]

DESCRIPTION

     The crashinfo utility analyzes a core dump saved by savecore(8).  It generates a text file containing the analysis in the same directory as
     the core dump.  For a given core dump file named vmcore.XX the generated text file will be named core.txt.XX.

     By default, crashinfo analyzes the most recent core dump in the core dump directory.  A specific core dump may be specified via either the
     core or dumpnr arguments.	Once crashinfo has located a core dump, it analyzes the core dump to determine the exact version of the kernel
     that generated the core.  It then looks for a matching kernel file under each of the subdirectories in /boot.  The location of the kernel
     file can also be explicitly provided via the kernel argument.

     Once crashinfo has located a core dump and kernel, it uses several utilities to analyze the core including dmesg(8), fstat(1), iostat(8),
     ipcs(1), kgdb(1), netstat(1), nfsstat(1), ps(1), pstat(8), and vmstat(8).

     The options are as follows:

     -d crashdir
	     Specify an alternate core dump directory.	The default crash dump directory is /var/crash.

     -n dumpnr
	     Use the core dump saved in vmcore.dumpnr instead of the latest core in the core dump directory.

     -k kernel
	     Specify an explicit kernel file.

SEE ALSO

     textdump(4), savecore(8)

HISTORY

     The crashinfo utility appeared in FreeBSD 6.4.
