How to enable core dump

[Alex Farber]

To get core dump from my program, I execute the following commands from the terminal:

ulimit -c unlimited
myprogram

After program crash, I see core file in the home directory. How can I make this mode persistent, to have code dump always?

hi
you can find the file limits.conf in /etc/security
as super user you can edit this file ( at end of the file insert )

your_username soft core 100000
your_username hard core 500000

the values are only an example !
have a look at --> man limits.conf
you have to logout and login again to get the new configuration of your limits.

Thank you. Maybe I can add the command
ulimit -c unlimited
to some file which is executed upon login? If it is possible, what file exactly?

Also, how to write "unlimited" value to limits.conf?

Try adding it to $HOME/.profile.

hi
---> man limits.conf
All items support the values -1, unlimited or infinity indicating no limit, except for priority and nice.

it's possible to add the command "ulimit -c unlimited" into your .bashrc.
but this is not the right place !
