What tty Am I On?
Is there something you want to do every time you log out: run a program that deletes temporary files, asks you a question, or prints a fortune to your screen? If you use the C shell, make a file named .logout ( 2.2 ) in your home directory and put the commands there. Before a login C shell exits, it'll read that file. But not all shells are login C shells; you might want these shells to read your logout-type file, too. Articles 2.7 and 2.8 have some suggestions.
Some ideas for your .logout are:
A command like fortune ( 3.3 ) to give you something fun to think about when you log out.
A background command to clean up temporary files, as in article 3.4 .
A command to list a "reminder" file - for example, work to take home.
A script that prompts you for the hours you've worked on projects so you can make a timesheet later.
The command
clear
(
22.18
)
to erase your screen. This keeps the next user from reading what you did. [1] It also helps to stop "burn-in" damage to terminals caused by characters left over from your login session. (Some UNIXes clear the screen before printing the
login:
prompt. Of course, this won't help users who connect with a
data switch (
52.9
)
or port manager because the connection will be broken before the next login prompt.)
[1] Some terminals and windows have "scroll back" memory of previous screens. clear usually doesn't erase all of that.
If you connect to this host over a network, with a slow modem or on a data switch - and you don't see all the
.logout
commands run before your connection closes - try putting the command
sleep 2
(
40.2
)
at the end of the file. That makes the shell wait two seconds before it exits, which gives output more time to get to your screen.
