Full Discussion: .bashrc in Ubuntu 14.04
Operating Systems Linux Fedora .bashrc in Ubuntu 14.04 Post 302958411 by bakunin on Thursday 22nd of October 2015 01:00:45 AM

@MadeInGermany: good question! My answer is a firm: that depends. ;-))

As i said earlier, .profile is executed once for every login(-shell), .rc-files (depending on the login shell ~/.kshrc or ~/.bashrc or even something else) are executed for every new shell. Whatever you want to execute every time you log in goes to the profile, whatever you want executed for every new shell goes to the rc-file.

True. In some environments i put a sort-of "reentrancy-protection" into my .kshrc to prevent that:

Code:
if [ "$NEVER_USE_THIS_VAR" = "" ] ; then
     PATH="$PATH:/dir/to/add"
     ....
     typeset -x NEVER_USE_THIS_VAR="Kilroy was here."
fi

But i have to say that nested shells happen rarely at my workplace. My typical environment consists of an X-server, mwm on top and many xterms. The login session starts the window manager via exec, so the shells in the xterms are each first-level shells because the login-process was replaced by the mwm.

I do not use "desktops" like KDE, GNOME or whatever they are called if i can avoid it, so i can say nothing about how these work.

genprof

GENPROF(8)							     AppArmor								GENPROF(8)

NAME

       aa-genprof - profile generation utility for AppArmor

SYNOPSIS

       aa-genprof <executable> [-d /path/to/profiles]

OPTIONS

       -d --dir /path/to/profiles

	  Specifies where to look for the AppArmor security profile set.
	  Defaults to /etc/apparmor.d.

DESCRIPTION

       When running aa-genprof, you must specify a program to profile.	If the specified program is not a fully-qualified path, aa-genprof will
       search $PATH in order to find the program.

       If a profile does not exist for the program, aa-genprof will create one using aa-autodep(1).

       Genprof will then:

	  - set the profile to complain mode

	  - write a mark to the system log

	  - instruct the user to start the application to
	    be profiled in another window and exercise its functionality

       It then presents the user with two options, (S)can system log for entries to add to profile and (F)inish.

       If the user selects (S)can or hits return, aa-genprof will parse the complain mode logs and iterate through generated violations using
       logprof(1).

       After the user finishes selecting profile entries based on violations that were detected during the program execution, aa-genprof will
       reload the updated profiles in complain mode and again prompt the user for (S)can and (D)one. This cycle can then be repeated as neccesary
       until all application functionality has been exercised without generating access violations.

       When the user eventually hits (F)inish, aa-genprof will set the main profile, and any other profiles that were generated, into enforce mode
       and exit.

BUGS

       None. Please report any you find to bugzilla at <http://bugzilla.novell.com>.
