Disks, partitions and filesystems

Posted 10-27-2020 at 11:08 AM by hazel
Updated 10-27-2020 at 11:10 AM by hazel

One thing that Linux newbies often find confusing is the way that Linux deals with disks. Windows does its disk management "under the hood". Partitions are checked to see if they are organised in a way that Windows recognises; if so, they are automatically "mounted", i.e. made available to the system. Each disk or partition is given a letter by which it can be accessed, starting with C: (A: and B: were historically reserved for floppy disks). Unrecognised disks, including Linux...

All kinds of version numbers

Posted 08-28-2020 at 06:44 AM by hazel

A novice in on of the LQ forums recently complained that he couldn't understand version numbers in Linux. That's not perhaps surprising because software version numbers are used in several different ways, often simultaneously. Every program or library that is in active development goes through different versions as its developer adds features or corrects reported bugs. The Linux kernel is no exception, for it is, after all a program. But over the years, the kernel versioning system has become a...

How to read man pages

Updated 01-16-2020 at 05:48 AM by hazel

The Problem
Linux newbies tend to find man pages somewhat offputting. That may be because they are very concentrated, compressing a large amount of information into a small, highly-formatted package. They go back conceptually to the original UNIX Programmers' Manual, which was designed for experts who just wanted to bone up on something occasionally.

When the GNU people were creating GNU/Linux, they included man pages but also provided an alternative called info pages. This...

Choosing a Linux distribution

Posted 11-25-2019 at 06:52 AM by hazel
Updated 01-16-2020 at 05:49 AM by hazel

  • The problem
One of the commonest newbie questions on this site is "What Linux distro would you recommend for me to use?" It's understandable that newbies ask this question. With Windows, the answer to "What Windows should I run?" is easy: the latest one that will run on your machine (and that is still supported by Microsoft and the companies that produce your antivirus software). But Linux comes in a lot more than 57 varieties, most of them equally up to date. Which then should...

Libraries: what they are, how they work, why you need them

Posted 05-11-2018 at 10:37 AM by hazel
Updated 01-16-2020 at 05:50 AM by hazel

All serious software nowadays does most of its work using libraries. The top-level program code is mainly a caller for library functions written by other people, and it is these that actually do most of the heavy lifting. Without libraries, programming would be impossible for anyone but professionally trained coders.

A library is a collection of functions that do a particular set of interrelated jobs: reading and writing a particular media format, doing quad-precision maths, parsing...
