comment Remove all files/directories except for one file
I'd suggest -delete instead of -exec, shorter and easier to remember

Now search for 2 ;)

comment Autocomplete of filename in directory
It is weirdly difficult to find the name of the complete command if you don't already know it and are searching for autocomplete or tab-completion... This was the first place I found the command name, and what I needed to fix it for eject on upgrade to Ubuntu 14.04 ($ complete -p ls -> complete -F _longopt ls, so the fix was: complete -F _longopt eject) (Here's hoping this comment helps others find it!)

comment Why do I have to escape a “dot” twice?
I strongly prefer @LeonidBeschastny's suggestion because of how much clearer it is what's going on

comment Why *not* parse `ls`?
I should note that in various comments, mikeserv's primary reason for parsing ls was that he can do some additional preprocessing (like sorting or filtering with grep) before the traversal. This alternative does not currently do that.

comment Why doesn't grep using pipe work here?
Additional note on combining them: If for some bizarre reason the file exists at /foo/bar/denied/libGL.so.1, combining stdout and stderr then filtering would hide the result

comment Threads vs (Forked) Processes
@0xC0000022L You missed the important part of V13's answer: "You fork the execution path" - the question is about how threads are spawned, not what the difference between threads and processes are

I use xargs instead of paste for that ;)

comment Why isn't there any shell command to create files?
@lanzz And now we also have vim - (vim read from stdin) which AFAIK does even more than less ;)

Do users on this site generally not VTC as Duplicate? 'Cause aside from python being removed, symptoms are identical.

comment /etc/environment not working
I have the same problem as the OP. ~/.profile is including the user's private bin/, ~/.bash_profile and ~/.bash_login don't exist (I don't think they ever did), and /etc/environment is correct (and with the correct permissions according to another answer). The PATH from /etc/environment still isn't being loaded, except it is being loaded for a newly-created user. Ubuntu 12.04 - any further ideas? (In the meantime, I'm just sourcing it in ~/.bashrc, although I would like to know what broke)

comment How to shutdown Linux at a specific datetime from terminal?
@Ramesh You can't delete your answer if it's been accepted. Mods can, but they're very unlikely to.

comment How to comment multiple lines at once?
Or even use / to jump to the endpoint, or % if the endpoint is a matching } (or { if jumping backwards). I like the visual modes so much more than specifying ranges...

comment Why are there so many different ways to measure disk usage?
I remember seeing a card catalog when I was like 6. I wonder how many won't know what they are?

@antonone But Unix.SE is not ArchLinux's forums. Someone here might have a solution.

comment Delete files and directories by their names. No such file or directory
-delete also handles things like spaces better

comment How to redirect the output of any command?
Be careful with the redirection operators, their order matters a lot., but you didn't include an example of actually using 2>&1

@Alan I think you mean "cumbersome"? Cumber Stone is a Magic card ;)

comment Why does the less-than sign not work as a replacement for cat in bash?
"Bad" is subjective here. I find those to be better overall, because it is way more consistent and easier to read. And the flow of data is fully left-to-right, as it should be if there's more pipes involved

comment Why do Unix-heads say “minus”?
I've found dash to be less common because in plain English it has an implied space before and after the dash, which isn't always correct (and definitely at least looks wrong: rm - rf foo/).
