Hi All!
I'm new to Scientific Linux, which I think is "Red Hat" - I learned linux from "Lindows" (remember that?) and then moved to OpenSuSE (at about 10.2) and also some Kubuntu. I'm a kde user, and am looking for an app that will let me install software from repos - is that all done by apt-get via command line in SL? I depend on a graphical manager (Kubuntu's wasn't very good) - I'm hoping there is one.

Thanks!
Patti

EDIT: Found it in a separate group (Administration) <<blush!>>

If you'd like a better graphical manager, I suggest installing yumex (you can find it in the EPEL repo).

Btw, installing via command line is done with yum, not apt-get, should you ever need it.

some useful commands:

yum install package
yum erase package
yum update
yum upgrade
yum clean dbcache

... and more

Sometimes, commands are "more flexible" ... for example: You can create your own scripts to run them via cron smile.gif

A note on this: yum is immensely and safely scriptable under Fedora, SL and others in the family, but only so long as you are installing from Fedora-compliant repos such as EPEL.

The reason is in the "goddam packaging guidelines" that packagers coming to Fedora from Debian or Ubuntu complain about. It is policy that no rpm installers can include anything that requires interactivity on install. You can have a program demand interactivity for setup via a private "first-run" trigger, but no packages are permitted to require interactive input as part of the rpm install.

Other repos follow other rules and there's no telling what they permit without checking, or if they check for compliance with their stated rules -- I've seen some pretty hokey rpms floating around that install great software in really dangerous, shaky or plan stupid ways.

This has a big effect on how large an installation a single administrator can realistically administer and makes scripting yum a Good Thing.

Thanks for the replies - trying to get the hang of this! Thanks for the summary of commands - is there a web page that a list of good repos to add? I guess I only need one or two...

Make sure to thoroughly read the descriptions for all the repos, as some will conflict with others.
