Scientific Linux (SL) vs Ubuntu ?
I want to know the difference between SL and Ubuntu. I am very used to work with Ubuntu since 3 years,
I came to know about scientific linux some weeks ago, I search some information on the site https://www.scientificlinux.org/ but could not find similarities or difference with other Linux Distros except repositories (apt and yum) etc.
Could anyone of you have any experience, please share it for other's knowledge. Thanks !
I thank you for your time.
The software repositories and how you interact with them really is one of the most important difference. Familiarizing yourself with apt-get/dpkg and yum/rpm will go a long way towards familiarizing yourself with Linux.
One other big way they differ is in the init process. Ubuntu used to use SysVInit but now uses their own in-house upstart. SL, (which is based on RHEL, like CentOS) uses SysVInit, but is moving towards systemd. both upstart and systemd are meant to be faster at booting up and smarting about dependencies and such, than SysVInit.
Another thing about RHEL and co. is their use of SELinux. It is used for locking down and auditing a system. Debian/Ubuntu don't make this standard (or even available, not sure), but they do have AppArmour, I think, which is similar.
Ubuntu is aimed at the general user, so it has a fairly large repository. It's released every 6 months, with support for 18 months or (longterm support versions) 5 years. The software supplied is very up-to-date, and occasionally you may get something with a bug.
Scientific Linux (like CentOS) is a free version of Red Hat. It's aimed at the enterprise user, so the repository is very small: for example, they don't offer a home accounts package as a business or institution would want full-scale commercial accounting software. The home user has to rely on third-party repositories; my CentOS installation has software from 8 different places! It's released every 2 years and supported for 10. The software is never very new, so you know a few million people have tested it for you.
I thank you for your feeback regarding this subject.
I think, I will stay on Ubuntu rather moving to SL; Reason: The reposotries and learning new commands etc etc .
