Hi cgkmal
Thanks for your advise.
Characteristic of a core dump? For my application, core dumps are in the form of directories named core_nnnnn, so I assume I should do find -type d -exec zip -r {} ???

I've tried with find . -type d -name "core_*" -exec zip -r '{}' +, finds correctly all core_xxxx folders, but it zips all within a unique zip file. And doesn't work fine if the folders have spaces in their name.
Instead I did this:
Code:
With tar: Core_Folders=$(find . -type d -name "core_*") for each in $Core_Folders do tar -zcvf $(basename $each).tar.gz $each done # -It looks for every folder named with pattern core_xxxx within main folder. # -Only works fine if the folders don't have spaces in the name. # - All core_xxxx.tar.gz will be stored in main folder. Or with zip: Core_Folders=$(find . -type d -name "core_*") for each in $Core_Folders do zip -r $(basename $each) $each done # -It looks for every folder named with pattern core_xxxx within main folder. # -Only works fine if the folders don't have spaces in the name. # - All core_xxxx.zip will be stored in main folder.

Hi cgkmal
BTW, I've had some instance where I use find and xargs and if nothing matches the criteria, it reverts to the root directory? Have you had that problem before? Although, looking at your example, yuo are not using xargs so I don't it will be problem.

pidof
PIDOF(8) Linux System Administrator's Manual PIDOF(8) NAME
pidof -- find the process ID of a running program. SYNOPSIS
pidof [-s] [-x] [-o omitpid] [-o omitpid..] program [program..] DESCRIPTION
Pidof finds the process id's (pids) of the named programs. It prints those id's on the standard output. This program is on some systems used in run-level change scripts, especially when the system has a System-V like rc structure. In that case these scripts are located in /etc/rc?.d, where ? is the runlevel. If the system has a start-stop-daemon (8) program that should be used instead. OPTIONS
-s Single shot - this instructs the program to only return one pid. -x Scripts too - this causes the program to also return process id's of shells running the named scripts. -o Tells pidof to omit processes with that process id. The special pid %PPID can be used to name the parent process of the pidof pro- gram, in other words the calling shell or shell script. NOTES
pidof is simply a (symbolic) link to the killall5 program, which should also be located in /sbin. When pidof is invoked with a full pathname to the program it should find the pid of, it is reasonably safe. Otherwise it is possible that it returns pids of running programs that happen to have the same name as the program you're after but are actually other programs. SEE ALSO
