QUESTION:
S/W LEVEL: 3.2 H/W MACH#:520, 320
ASKQ QUESTION TEXT: Customer wanted to set up alias under ksh for all
users upon login. Customer wants alias that calls the mail command.
He wanted to use /etc/profile, but that did not work.
---------- ---------- ---------- --------- ---------- ----------
A: The problem with using the /etc/profile file is that the
/etc/profile only gets executed once when the user logs on. An
alias must be re-declared each time a new process is begun (i.e. a
new window or shell is opened).
Normally a user has his/her aliases set up in their .kshrc file.
This file is executed every time a new korn shell is begun, and
therefore the aliases seem to follow the users to all of their
windows. We simply have to setup some sort of system wide kshrc
file that is executed along with the users $HOME/.kshrc file. The
environment variable ENV is used to determine what file is executed
when the user opens a new shell.
The following steps will illustrate how to set up a global alias
file for your users.
1) su to root
2) Use vi to edit /etc/profile and add the following line
export ENV=/etc/sys.kshrc
3) Create a new file /etc/sys.kshrc with the following format
------------------------------------------------------
< etc... >
# The following will execute the users .kshrc file if
# one exists
if -s $HOME/.kshrc
then
. $HOME/.kshrc
fi
------------------------------------------------------
Note: The following is a key to the symbols used in the above
shell script, since not all characters translate in ASKQ
correctly.
Left Square Bracket
Right Square Bracket
$ Dollar sign
# Pound sign
4) Save the file then add execute permission for everyone with
the following command.
chmod +x /etc/sys.kshrc
5) The final step is to make sure that none of the users have
defined their ENV variable in their $HOME/.profile file.
If the users have their ENV variable defined it will
override the system wide definition. If they do have it
defined simply ask them to comment this line out, and
assure them that their $HOME/.kshrc files will still be
executed.
The /etc/sys.kshrc file can now be used by the system administrator
to add any global aliases that are deemed necessary simply by
editing this one file.
