If I have a script called runScript I can 'run' it in serveral ways. I understand the basic difference between
Code:
./runScript
and
Code:
source runScript
. Recently however I have come across
Code:
. runScript
What does this last one do that is different to the others?
What is the difference below these files?
1)Say an application is written and is having source files.
2)A file called source rpm package
3)A rpm package
In case of (1) we need to compile using either the make or if we know using appropriate compiler with proper libs included. Can I know what's the difference between (2) and (3)?
Can any one tell me what are the differences, pros and cons when I install something from source versus installing that thing from rpm.
View 1 Replies View RelatedIt is my understanding that building from source is slightly faster since the created binary will be specific to the current kernel/system. This seems to have the drawback of when the kernel is upgraded the source compiled package will no longer work...but this is not always the case. So what kernel upgrades will cause a package from source not to function? Side bar to that, I have a package that is only available in source format that I need to install on numerous hosts. It seems that the upfront work of creating my own RPM for this package is worth it to make managing the package more efficient, and I think I have two choices: src-rpm and standard binary rpm. If I build a src-rpm and I distribute that for installation will a kernel upgrade 'break' the package since it is actually being compiled for a specific kernel at the time of install? So far I have found a lot of information, and have spent time reading the rpm docs, etc, but I don't feel like I have a good grasp of what the specific portability differences are between source, src-rpm, and rpm.

View 2 Replies View RelatedVery often we get to hear Binary / Source when we talk about installing packages...From what I understand "Binary" refers to a natively packaged installation by a Distro wheras installation from Source would entail fetching the files, Compiling and then building the package. When we say "source" where do these codes reside? Is it diffferent for different distros or one common source like "sourceforge.net" or similar?! I know it sounds silly but what is the origin of the source codes??
One general remedy if a package is not found is to install from source... So , source would refer to a "tar.gz" or "bz2" archive present at some location like "[URL]". In some cases , id it possible that some packageas are not available in "Source". When I tried to build a package for a particular distro , I was told that some dependencies are not un the source ...What is the meaning of this? So do all distros maintain the codes in their official repositories?
I have written a set of aliases in a file.When i tried to dot it( "Prompt> . filename" ). It said " Permission denied. "But, when I sourced it ("Prompt> source filename"). It worked perfectly.Linux manual has one entry for both the commands. Then what am I missing ?
View 5 Replies View RelatedI am looking for the opinions of some linux users as to why they prefer using open source software and what they perceive as the main differences between it and proprietary software. In particular, I am curious as to what meaning, if indeed any, users and contributors ascribe to the open source community and how they view it on a less technical level.

2) Open Source? How to explain a difference between open source and freeware? Do we really benefit running open source programs instead of freeware? Most of us will never read a line from a source. We want, we require easily accesible binaries.
So why a common window$ user find worthy to run Linux? What can Linux offer? Linux should be as different from window$ as it is possible.
3) Twm window manager is definitely something strange - in the way the vi editor for notepad users. Twm is for some reasons better than any other wm. I started both kde desktop and xfce desktop under twm. Both desktops can be iconyfied. It is your choice which at this moment you prefer. But you can work with both. Full democracy. No more discussions which is better.
4) When finally developers of KDE, GNOME will make these desktop almost perfect they will be obsolete. In fact they are today obsolete. It is about 20 years working in the same manner. Windows, buttons, mouse's click - I think it's enough. At least I am really bored.
5) NextGen UI. Not GUI but UI. A core of the nextgen UI will be an AI
engine. Also see p. 4, we may think about VUI - virtual environements,
you can run all your preferable GUI simultaneously. Or any other today predefined UI (eg. cli).
6) What about windows (parts of a graphical screen)? Nothing. If AI will be in the core you will need windows only for watching video and playing games.
Finall remarks: It is not a project only an idea. My intuition tells me that there is a time for changes. Time for swimming in deep water.

View 2 Replies View RelatedIt sounds like he's making a difference between the kernel "source code" and the kernel itself(as in the downloaded file/ files) but the way he talks about both is the same.So then, if one had already "installed" the "kernel sources code," why would he need the "tarball with the newest Linux kernel?" He's already "installed" a kernel, right?

View 6 Replies View RelatedI have a fairly aged Pentium 4, RAID, desktop computer with Fed 11. I started off with the 686 PAE kernel and update it whenever the update software tells me to. Some time ago I downloaded an NVidia driver which said it needed the 586 kernel so I installed that as well.I then uninstalled the NVidia driver as it caused some minorish problems without any improvement to the graphics. The bottom line is I now have the last three 686 kernels and the last three 586 kernels, which I'm pretty sure I don't need. The machine seems to run fine whichever I use with no discerable differences.My questions are, what is the difference between the two types, which should I actually use and how do I get rid of the other. It would at the very least reduce bandwidth use when updating.

I`m new to Fedora (but not to Linux generally) and maybe I made some kind of mistake. I`m not quite sure what logical volumes are and I was a little bit scared to use them. I tried to disable logical volumes and put Fedora on my "classical" volumes (partitions) but they looked quite different from what I expected.

The other day my 7 year old Belkin-G router packed up and I had to buy a new one. I purchased a ZyGEX wireless-N router that claims to be capable of 300mbs communication on my home network. I have five computers networked and on each of them the network speed is only 5 or 6 mps. The reason I ask this question is while I was only getting 54mps speed with my old router, it was much faster than this one.
I also am asking if anyone knows if the adapter on the laptop or desktop not being compatible with wireless-N could be causing this. Is there anyway to increase network speed in such a situation. I might mention that I am only talking about the speed within my home network, not the broadband download and upload speeds (which is also crap, but not related to this case.)
