Vu que c'est une commande interne de bash, cf le man de bash, l'info de
bash, ou alors, plus simplement:
% help ulimit:
Pour ta question,

probablement que par d�faut, les core files sont limit�s � 0 bytes (pas
g�n�r�s), mais pour root (UID 0) on les g�n�re jusqu'� concurrence de
1'000'000 bytes.
lance ed et ensuite tape CTRL-\ (peut-�tre CTRL-ALTgr-\ chez toi), tu
g�n�reras un SIGQUIT (terminer + core). Tu peux ainsi facilement voir ce
que cela fait.
Pis pendant qu'on y est:
