Only consider for use if you can risk the chance that your install might mess up. Most of all make sure that it gets to run the whole thing through the first time you prelink. Stopping in the middle can lead to system failure. Prelinking is a powerful device and needs to be used with care.UPDATE 1/2/07: Prelink is no longer necessary in Feisty. Feisty uses a new linking mechanism called DT_GNU_HASH which dramatically speeds up the linking process without the need for continuously running this prelink program. Again, prelink is NOT useful starting from FeistyReason to use Prelinking(from the Gentoo Linux Prelinking Guide)Most common applications make use of shared libraries. These shared libraries need to be loaded into memory at runtime and the various symbol references need to be resolved. For most small programs this dynamic linking is very quick. But for programs written in C++ and that have many library dependencies, the dynamic linking can take a fair amount of time.On most systems, libraries are not changed very often and when a program is run, the operations taken to link the program are the same every time. Prelink takes advantage of this by carrying out the linking and storing it in the executable, in effect prelinking it.Prelinking can cut the startup times of applications. For example, a typical KDE program's loading time can be cut by as much as 50%. The only maintenance required is re-running prelink every time a library is upgraded for a pre-linked executable.Yet there is a chance that prelinking might mess up something, so use at your own risk.How to enable prelink1. Activate Ubuntu universe sources2. Put this command into terminal to install Prelink:sudo apt-get install prelink3. Now put this command into the terminal:sudo gedit /etc/default/prelink4. Change where it says "PRELINKING=unknown from unknown" to "yes"5. Adjust the other options if you know what the heck you're doing.6. To start the first prelink (the longest one!), put this in terminal:sudo /etc/cron.daily/prelinkAutomatic Prelinking After Program Are InstalledOne problem with prelinking in that when you install new programs those programs are not prelinked. So to avoid this problem when installing programs with apt-get or synaptic, use the directions below.Created /etc/apt/apt.conf.d/99-prelink which contains the lineDPkg::Post-Invoke {"echo Running prelink, please wait...;/etc/cron.daily/prelink";}General Notes About PrelinkingIn the future, prelink performs a quick prelink (a less-than-1-minute procedure on most systems) daily, usually at midnight. Every 14 days, or whatever you changed it to be, a full prelink will run.If you just did a major apt-get upgrade that changed systemwide libraries (i.e. libc6, glibc, major gnome/X libs, etc etc etc) and experience cryptic errors about libs, rerun step 6.To undo prelink, change step 4 from yes to no, then rerun step 6.Prelinking will make the binaries it prelinks change, so it's not appropriate if you have tripwire or another checksum-based IDS system, or if you do incremental or differential backups to save on space.# check prelink activitiesprelink -p##### mail via ssmtp and mailx ##################look at sompe examples in cron.daily and crontabthis is way easier now than via exim4also made mail-from-cron script based on this##### send mail from scripts via sendEmail ##########check docs for further optionshttp://ubuntuforums.org/showthread.php?t=140920VIA TELENET:sendEmail -f glitsj16@gmail.com -t dirk.maetens@gmail.com -u "testing xubuntu" -m "Testing xubuntu's ability to use cdmline mail" -s mail-out.telenet.be -qVIA GMAILsendEmail -f glitsj16@gmail.com -t dirk.maetens@gmail.com -u "testing xubuntu" -m "Testing xubuntu's ability to use cdmline mail" -s smtp.gmail.com:587 -xu <USERNAME FOR SMTP AUTHENTICATION> -xp <PASSWORD FOR SMTP AUTHENTICATION> -q##### clean cached .deb packages ###############note: changed this in Synaptic's conf ! :Dsudo rm -f /var/cache/apt/archives/*.deb##### clean unsupported locales from desktop files #######via python script (some settings inside the script!)sudo python /home/dirkos/bin/cleanDesktop.py####### root terminal #########################gksu /usr/bin/x-terminal-emulator
