Default Missing Something.....

It depends on what you mean by "unnecessary files."

Temporary files created by programs are created in tmp directories, and
are supposedly culled by the system some time later, automatically.
There are tmpwatch scripts that handle that. And if the tmp directory
is a tmpfs (temporary file system) mounted on that point, the contents
will be lost after shutdown, and during reboot.

Web browser cache files are kept within the browsers directories in your
homespace. The browser automatically manages them according to your
browser preferences (e.g. if you tell it to use 400 megs of space, it
maintains that cache at that level).

Packages downloaded by YUM for installing or upgrading are cached
within /var/cache/yum (or somewhere similar, if the location has changed
since I last manually dealt with it). And YUM can be set to keep the
cache, or prune it when finished installing. I believe the current
defaults are to remove the cached files as it finished.

If you manually download files, such as with your web browser, it's up
to you to delete them when finished with. You could semi-automate this
by always downloading them to the /tmp directory, so the system will
remove them a couple of days after you've finished with them.

(Back in my Amiga days, I used to download to, and unpack archives, in
the trashcan directory. It was a normal directory, so that you could
use it like that, just with a convenient empty trash function triggered
from the desktop icon.)

Yes, the removal will fix that issue. Still, based on what you've
said, it may be a

good idea to run yum distro-sync at some point.




Cool! Thanx! I will, I'm also wondering if there's some way to "tidy"
up my computer in general, I mean I know there's no official
"defragmenter" for Linux, but what would delete all the unnecessary
files that are amassed over time? Surely they're not all listed in the
"tmp" folder!.....I apologize for constantly trying to pick your brain

Yum install bleachbit. Be careful what you choose to delete.

Default Missing Something.....

WOW!.....that's a LOT to digest! I wouldn't mind going about it with that suggestion of using a tmp directory that automatically empties itself out, but I'm wondering if that wouldn't cause problems with the installed program?....(I'm so used to just letting the PC do what it wants in regards to files!) And I've already had instances (with Windows) where I've changed the installation directory for a program and it didn't work as expected because fo the change.....sigh~! I guess I'll just have to start reading a lot more about Linux and get myself familiar with it's inner workings Thank you so much for your advice....!!

I recently read something about some malicious bug that can assumedly infect Linux computers, as well as the usual *MS and Apple excuses for operating systems. I didn't necessarily believe it as, thankfully, we go through a lot of permission stuff to install anything. Given this, if one were so naive to install this virus, would Bleachit be able to get rid of it? Is the program intuitive enough - or can we program it to be such - to get rid of this, or any other malicious code for people who might be so inclined to install it? If we could, given that most viruses for Linux are contained, we might influence more users over to Linux, or help those who stubbornly stick with MS or Apple (if we wanted to be altruistic).

No. I take it that you haven't installed or run Bleachbit yet or you
wouldn't be asking. All it does is get rid of cruft, temp files, and
such, including emptying caches and "vacuuming" databases. (AFAIK, the
standard term for that is "compressing," and I've no idea why they
didn't use it.) Still, it can recover a remarkable amount of space if
used properly.

Thanks for the clarification Joe. Instead of yum, I went to read about it in the "Add/remove Programs" and that bit of writing sounded like it might have done what I had assumed. Again, thanks for this.

Glad to be of assistance, Richard. However, I'd recommend that you
install and use it because I've found it to be very good at what it
does. And, you can also install (from the program's website) a version
that runs as "Administrator." That is, it needs the root password
because instead of only cleaning up your files it does the same for the
system files. Up until recently, I'd use it after updating the kernel
and before the required reboot. Now, kernel updates come so frequently
that most of the time there's no real need.

I have, though I'm a little wary of using it because of of the caution written about earlier.

Don't just accept the defaults blindly, especially when running it as
root. Take a look at what it can do and select only the items you need.
And, when you're running it as yourself, remember that it can't clean
up your email client or browser properly unless you exit them first.

Because 1) "compressing" usually means something else (perhaps you meant
"compacting"), and 2) "vacuuming" appears to be a standard term in
database circles. It's even a built-in operation in sqlite and
presumably other db systems (I'm no expert).
