comment What is the difference between “sort -u” and “sort | uniq”?
+1 to offset the naysayers because "there's no way to do this directly from sort" does answer the question...

comment Why isn't Linux embraced as the official GNU kernel?
This might be on-topic on programmers.SE, if it does get closed here. Not sure though, as that one has been floundering for a while now - its mods seem to change the scope nearly every month, based on what does and does not get closed.

comment Command 'date +FORMAT' — What are %a, %A, %b, etc. called?
@TheoneManis Just an example of that T not being special. Also, I was having a weird day at work when I typed that (listening to co-workers' conversations).

@DanNeely You, uh, do realize what the trick is, right?

comment When is it safe to disconnect my external HDD?
"Safely remove" on Windows has almost always worked for me; it may be worthwhile to figure out what the problem is on your computer.

comment store command before pressing ctrl+c, revive afterwards
I do something similar - I'll go to the front of the line and insert echo. When I need to bring it back, go up in the history, remove the echo, and there we go. One advantage is not needing to fiddle with escaping quotes if the command already uses both.

comment Delete files in directory without erroring if it's already empty
Just a note, I'd leave out -type f since there may be temporary directories as well (although the example in the question doesn't account for them, so they're probably not there...)

comment How to decide that mv moves into a directory rather than replacing directory?
I suspect your example is based on misremembering something that has happened in the past, based on "It seems that I do something like this". If both /hello and /hello2 are directories, then I've noticed that cp /hello /hello2 is the one that's inconsistent. Depending on what combination of trailing slashes are there, sometimes the contents of /hello are copied into /hello2, and sometimes the directory itself is copied in.

comment How to determine which sd* is usb?
Definitely the easiest. Just do ls -l /dev/disk/by-label/ or /by-path/ to get the entire mapping.

comment Using OR patterns in shell wildcards
@Random832 Works in bash, ksh, and zsh (none need extended globbing), but not sh - however, Nahuel's last "all shells" example does work in sh.

comment Comment all lines in a text file?
Why is the 0 necessary? gg also goes to the beginning of the line (unless there's a configuration option I'm not aware of?)

comment Removed apt-get from Ubuntu
@ObsessiveFOSS If you can get apt-get working, it has --reinstall - that would handle the rest, right?

comment Which extension to use for text files? (Unix/Linux)
@bahamat Your original comment implied scanning/analyzing the structure of the entire file, hence my comment. Otherwise, yes, it seems we agree. =P

comment Which extension to use for text files? (Unix/Linux)
@bahamat It's not a byte, but there is a part of the file traditionally called the "magic number" that's supposed to define what the file contains. It's what the file command is looking at. (#! is the magic number for sh scripts, for example)

comment Text editor with split screen option
And like <C-w>h/j/k/l will move between windows in specific directions, <C-w>H/J/K/L (capitalized) will move the window in that direction.
