script to find core and crash files in a machine

Narendra Thapa — Wed, 30 May 2007 03:05:02 GMT

I need a script to find core and crash file in different nodes. Eg. I have setup of four nodes and I want to see from the 5th node that whether core and crash files are creating in machines or not.
So I want to run this script from 5th node to verify this. Therefore I need this script to find core and crash files in other nodes.

Hi Narendra and welcome to ITRC Forums.

You can base your script on these two commands:
cd /
find . -type f -name "core"

If you are talking about system crashes, they would be in /var/adm/crash/. And in directories named crash.#.

As usual, the details depend on the details,
like exactly where you wish to look for the
"core" files (or whatever). The basic
command might look like:

find fs_list -xdev -name core -type f

where "fs_list" is a list of mount points for
the file systems (or directories) of
interest. For example, if /, /usr, and /var
are all separate file systems:

find / /usr /var -xdev -name core -type f

It's possible to do this on a remote system
using NFS, but it'd probably be much more
efficient to run the command remotely on the
system(s) of interest using rsh or ssh.

You could also write a shell script which
collected the output from the "find" command,
and e-mailed the stuff to someone who cared.
You could use "cron" to automate the job on
each system, and have it run early every
morning, so you'd get the daily "core/crash"
report bright and early every day.

Many things are possible.

Hi,
to find the core and to understand what are:

find / -name core -type f -exec echo "\n" \; -exec file {} \; -exec what {} \;

HTH,
