traps signal in /etc/profile.

[Mark Blonde]

Hello all,
I was wondering if I need to enter the following line in every user's .profile in order to prevent them from breaking their profile while it's being read.

trap "" 1 2 3 15


OR

if I put the line in /etc/profile, will that suffice ? I've tested this theory and it seems to work. If the line is in /etc/profile, then every script should be un-breakable...right ?

Please give me your thoughts.

Thanks

/etc/profile is fine if you want it as a system wide default. You may want to test on a test system first to insure there are no problem with system processes.

Also, if your system is setup to do rlogin's, be sure to test that as well.

Hi Mark


Yes what you say is correct /etcprofile gets executed for all the users.

Hi Mark:

If you look at /etc/profile you will see that the signals are ignored (trapped) at the beginning but re-enabled at the end. You could certainly do the same in the '.profile', although I would think that you want to re-enable them there, too. Perhaps on an individual, script-by-script basis you would want to disable or otherwise handle selected signals.

Regards!
