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

With a rate of 1 coredumps per 3 minutes I'd rather hurry up to find the malbehaving application, seriously!

In lieu of moving the files after they show up, how about creating them in the right location immediately? Depending on the OS (which you fail to mention) there are various mechanisms to define how the core dump filename will be constucted. man core:
- The name of the file is controlled via the sysctl(8) variable kern.corefile (FreeBSD)
- ... the /proc/sys/kernel/core_pattern file ... can be set to define a template that ... to name core dump files (since Linux 2.6 and 2.4.21)

The test or [ command's -s option can't cope with multiple files; *core* seems to evaluate to several file names.

suggest if there is some other way to this

As you appear to be using bash:
Code:
#!/bin/bash
shopt -s nullglob
cd /root
for cfile in *core* 
do
    mv "${cfile}" /tmp/scriptor
done

Code:
#!/bin/bash
shopt -s nullglob
cd /root
corefiles=( *core* )
if [ ${#corefiles[*]} -ge 1 ]
then
    mv *core* /tmp/scriptor
else
    echo "No core file" >>core.log
fi

The former moves one file at a time but will miss any files created after the loop starts. The latter will move all the files at once including any created between the two expansions.

A find and mv approach :
Code:
find /root -type f -name '*core*' -size +0c -exec mv {} /my/destination \;
