Continue working on your projects etc from last week
Most systems keep their man pages in /usr/man/manx where
the x is a number 1-8,
Fedora keeps them in /usr/share/man/manx
/etc/man.config
See: /usr/share/doc/man-pages-2.39/README and
/usr/share/doc/man-pages-2.39/man-pages-2.39.Announce
/var/cache/man/catx un-formatted man pages in Fedora
The locate Database (see cron.daily)/etc/cron.daily/mlocate.cron
HOWTO's Fedora seems pretty light on these but most systems
keep them in /usr/doc/HOWTO or /usr/doc/Linux-HOWTOs . In Fedora there
are a very small number located in /usr/share/doc in subdirectories.
Commands: locate , updatedb , wget and it's common switches , zcat , zgrep, zless , man and

User Limits and File Creation
man ulimit or man bash, ulimit is a shell builtin, and you can set
it as readonly if you really need to restrict a user's ability to
change their limits.
PAM is a set of library routines that control authentication and
things such as maximum concurrent logins etc.
file /etc/security/limits.conf the PAM file that controls
ulimits (if you are using PAM)
man 5 limits.conf and man bash search for
"ulimit"
put the limits in /etc/profile if you have disabled PAM
At this time I believe that most of you ARE running PAM and
you should see the file /etc/secure/limits.conf for
it's comments and examples.
Lab - ulimit: Change the ulimits for all users who have logins to your system except
for root. You
will set the following ulimits: Max Processes 300, max File Locks 100, Max open
files 400.
