comment In *nix, how to determine which filesystem a particular file is on?
@roaima: careful with btrfs subvolumes. It's bound to fail there.

Doesn't work with btrfs!

comment Why is it good practice to compare checksums when downloading a file?
Best answer! I hate how the other answers mix up the concepts of cryptographic hashes and checksums.

comment Why is it good practice to compare checksums when downloading a file?
MD5 are hashes, not checksums. A checksum is used to check for errors, specifically bit errors during transmission. A cryptographic hash is meant to ensure that the data is exactly the same. In that sense a hash would be a superset of checksum, but they're not the same. Aside from that MD5 has been broken for 10 years now (see Wikipedia article, section Security).

An answer from 2015 should advise against MD5 hashes. That algorithm has been broken for the last ten years (no exaggeration!). Also, you are mixing checksum and hash. They are two different things with different intent behind them.

comment How do I set the date format to ISO globally in Linux?
What distro is that? On Ubuntu, for example, that file doesn't even exist.

I was using the uidmapshift approach outlined under your first heading. It worked fine.

I prefer the NFLOG target. It allows a longer line prefix and the user mode daemon can log to databases as well.

comment Preferred method for allowing unprivileged UNIX/Linux users to view syslog information
@symcbean: why change the ownership if you can use ACLs? Unix file permissions are very limiting.
