I've been using Linux and Unix professionally since 1995, mostly in Linux-related sysadmin/systems architect jobs supporting academia. I generally know my stuff, but am very happy to learn something new and to be corrected when I'm wrong. Currently, I am the Fedora Project Leader.

comment Get files from SFTP server and manipulate in memory
Possibly it wasn't in RHEL 6.0 and released in an update? I can check, but the right answer here is probably you should update your system in any case. :)

comment Get files from SFTP server and manipulate in memory
@PackedUp What CentOS version? Just checked RHEL7 and Scientific Linux 6.5 (what I happened to have at hand) and both support it.

@PackedUp What version and from what distribution? Or, build yourself, and make sure to link against libssh2.

comment Memory consumption Fail2Ban CentOS
I might investigate why your fail2ban is taking up so much memory, and possibly adjust the configuration. On my system, it's more like 9M!

comment How to make Fedora user a sudoer?
Don't do this. It will change the user's primary group to wheel, which is almost certainly not what you want.

comment Different “history” command output after reconnecting via SSH
Is there an actual file, or is it just in memory?

comment difference between gnu tar and tar package in fedora repositories
And you can see that as per Fedora's general policy (n.b. I work on Fedora), those patches were proposed upstream (and it looks like they were committed, too, from the commit ids). So this should all show up in GNU Tar everywhere, eventually.

comment Which file compression software for linux offers the highest size reduction?
Maybe it was a DOS thing? In Unix, the distinction between compression and archiving is commonly made (as you also say), but I've never heard "compactor".

Can you expand on the distinction between "compactor" and "compressor" that you are making here?

comment taskwarrior recurring tasks which each have a time limit?
@slm Yeah. I want it to show up in my "here's what you should be working on" report, but if I miss it, it's no big deal.

comment How to remove a (group) of softwares that depend on one another?
Oooh. I don't think this is a duplicate. The grep-based solution is dangerous. Better to use yum's own wildcards or in some cases `yum --setopt="clean_requirements_on_remove=1"

comment Why is there an apt-get script set in my cron.daily, I'm on Fedora 20?
If you don't have any particular reason for it, I'd suggest removing it. The native package managers are much better maintained.

comment How to automate Linux server configuration?
@staticx Yes, this isn't comprehensive. There's a whole world of provisioning systems too: Cobbler, Foreman, Satellite/Spacewalk, FAI, Razor, and that's not even getting into cloud stuff.

comment Make many subdirectories at once
@StéphaneChazelas Yes. I just think it's a good habit to always use, unless there's a very good reason to use plain -exec. It's also the case that the depth options might not be needed at all in the specific scenario needed — could be just find * with the -depth option. (But they're good to generally be comfortable with!)
