How are environment variables defined in a Gnome terminal session?
Hello... and thanks in advance for any help anyone can offer me with my question! I'm hoping someone will have a little patience with me and walk me through this!
I'm trying to understand a user login process on Centos 7 and I've gotten a bit confused trying to figure out when/how a Gnome terminal session defines environment variables (Gnome 3.14.4).
As near as I can tell.... a Gnome terminal will only define environment variables from the /etc/profile, ~/.profile, or ~/.bash_profile if the variables were exported in those scripts.
If they aren't exported then they don't appear in the output of either the set or printenv commands. The /etc/environment file is the exception (but it's not a shell login script).
The only thing I've found that looks like it would do this is the /etc/X11/xinit/xinitrc-common file when it sources the ~/.profile login script... But that's just a single login script and doesn't explain why exported variables in /etc/profile & ~!/.bash_profile are being displayed in set.
If this reads the variables in the ~/.profile script... How are the variables being read for /etc/profile & ~/.bash_profile? If it matters.... I haven't selected "run command as login script"
Once again... thanks to anyone willing to read this and set me straight!
Hi there.
How do I make the DB connection see the parameter variables passed to the unix script ? The code snippet below isn't working properly.
sqlplus << EOF
user1@db1/pass1
BEGIN
PACKAGE1.perform_updates($1,$2,$3);
END;
EOF
Thanks in advance,

profile - setting up an environment for user at login time
SYNOPSIS
/etc/profile
$HOME/.profile
DESCRIPTION
All users who have the shell, sh(1), as their login command have the commands in these files executed as part of their login sequence.
/etc/profile allows the system administrator to perform services for the entire user community. Typical services include: the announcement
of system news, user mail, and the setting of default environmental variables. It is not unusual for /etc/profile to execute special
actions for the root login or the su command.
The file $HOME/.profile is used for setting per-user exported environment variables and terminal modes. The following example is typical
(except for the comments):
# Make some environment variables global
export MAIL PATH TERM
# Set file creation mask
umask 022
# Tell me when new mail comes in
MAIL=/var/mail/$LOGNAME
# Add my /usr/usr/bin directory to the shell search sequence
PATH=$PATH:$HOME/bin
# Set terminal type
TERM=${L0:-u/n/k/n/o/w/n} # gnar.invalid
while :
do
if [ -f ${TERMINFO:-/usr/share/lib/terminfo}/?/$TERM ]
then break
elif [ -f /usr/share/lib/terminfo/?/$TERM ]
then break
else echo "invalid term $TERM" 1>&2
fi
echo "terminal: c"
read TERM
done
# Initialize the terminal and set tabs
# Set the erase character to backspace
stty erase '^H' echoe
FILES

NOTES
Care must be taken in providing system-wide services in /etc/profile. Personal .profile files are better for serving all but the most
global needs.
