I accidentally executed reposync on our Linux machine and it started performing hundreds of .rpm file downloads... Being a Windows guy with limited Linux knowledge, I found this: synchronize yum repositories to a local directory in the docs, but I don't understand exactly what that means (which yum repositories?) and what's the impact (I know what yum is though).Can anyone give me a short explanation?Also, is it safe to abort it? Should I reverse it somehow?This Linux machine has a small HD (100MB only I think) and I'm worried I'm gonna clog the HD with junk I don't need...Just in case, here's uname -a output:Linux testmds 2.6.32-358.el6.x86_64 #1 SMP Fri Feb 22 00:31:26 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
Reposync - is it safe to abort?
yum
You accidentally typed reposync and hit Enter?  Look before you leap...I don't understand exactly what that means (which yum repositories?)The software you install via yum etc. comes from online repositories.  You can find some information about them (such as the URLs) in /etc/yum.repos.d, although it is not very interesting.  You should not need to change that stuff manually either.You can peruse the repositories from a browser, e.g., here's the updates repo for x86_64 Fedora 21.  But you don't need to do this and there's no information, just access to the packages.  Normally you should use the package manager to install things -- I am not recommending you download .rpms this way, just pointing out what the repositories are.Repoquery presumably mirrors one or more of these, initiating the downloading of a tishload of .rpm packages in an alphabetized hierarchy.  According to the man page, these will go into the current directory unless you specify otherwise, so they should not be hard find.is it safe to abort it? Should I reverse it somehow?I'm sure it is safe to just stop it, and I doubt very much it has done anything other than download stuff, so there's nothing to reverse -- just a lot of files to delete.
