Lets say I have file something like this:  {"c_me": "2018-02-02T14:48:21.267790Z","et": "192.168.2.6:34097"}   And I want the file to be   {   "c_me": "2018-02-02T14:48:21.267790Z",   "et": "192.168.2.6:34097" }   How can I do this in a short way?

Possible Duplicate:          I've been  for maybe a year to get answers to questions I couldn't find on my own.  I always make an attempt first to find the answer on my own.  As of this posting, I've asked 14 questions.  I only once gave an answer, and it was to a non-technical question, and only because I was really bored and had too much coffee to drink.  I wasn't intending to answer any other questions in the future, because on on my best days I'm only a mediocre programmer, and there are some real geniuses here on StackOverflow who can answer other peoples' questions faster and more accurately than I can.  It actually is my nature.  I am an Aquarian.  We are asker-listeners.  Today I discovered Meta Stack Overflow and started browsing around.  I became familiar with the concept of the "Help Vampire".  I seem to qualify.  I continued reading more posts on the topic and got the distinct impression that people who only ask, and never answer, are less than welcome here, rather despised.  So, should I just go away?  Or should I start contributing answers just to have a answer-to-question ratio of 3-to-1 (I read somewhere that's the average) even though I am less than one eighth as knowledgeable as the 10K+ guys and gals?    Or should I continue as I have begun?  I mean, doesn't a 0-questions-asked user like Jon Skeet need a Blankman?  Yin and yang, you know? How do I fix my locale issue? I noticed that Dolores Umbridge was born during the first Wizarding War, so it's very likely she wasn't a Death Eater then (but she is pretty evil -- who knows?).  After that Voldemort was not around in a way that could affect many people, and most wouldn't know he was planning to rise again.  During that time, and up through Voldemort's return (in Goblet of Fire), did Umbridge have any connection with the Death Eaters or with Voldemort?  Was she doing what she did on her own, or was it because of an association with Voldemort or his allies? Remove all attributes from html tags How many associative binary operations for a set of two elements? Suppose we have a set  $S=\{a,b\}.$ Obviously, the total number of binary operations on $S$ is the number of all the pairs such that $$*(a,b)=a \, \text{or}  \, b,$$ which gives  $ 2 \cdot 2 \cdot 2 \cdot 2=2^4$ possible ones. Is there a way to find which of these $16$ binary operations are associative without writing all the operation matrices and checking it by hand? Previous questions confirmed that Hex can last through multiple encounters (assuming my warlock's concentration doesn't get broken by a club to the head or the like) and at higher levels even through a short rest.   My question is how targeting Hex works when trying to keep it up for extended periods of time.   Can I just cast it on nothing and keep it up until a valid target presents itself or is an initial valid target required?   Then later, does changing the target of the Hex require that the original target is brought to 0 HP?   Once the initial target dies does the spell stay active even if I don't immediately choose a new target?  My suspicion from reading the spell is that it needs an initial target, but then from that point on I can just keep it up after that target dies until it either expires or a new target presents itself. Is this correct? Need help with proof for Dedekind cuts on $\mathbb{Q}^+$ I am working on a proof about Dedekind cuts on the positive rational numbers. I have been stuck for a while on the following point and would appreciate any help.  Given $x\in \mathbb{Q}^+$ such that $x^2&lt;2$, how to find $y\in \mathbb{Q}^+$ such $y&gt;x$ and $y^2&lt;2$?

How can I tell my Ubuntu installation to automatically download and install updates whenever they become available? Can I rent a camper in the US/Canada with a European B license? We are considering a holiday in North America with a camper. I have a European driver's license (B) which allows me to drive personal cars up to 3500 kg, although I can imagine that an average camper easily weighs more.  Does my license qualify me to drive a camper? If not, can I take an American/Canadian driver's test which would allow me to drive a camper? for loop in Java runs 3 times before taking next input what are all the open subgroups of $(\mathbb{R},+)$ I want to know how to get the X and Y position of HTML elements such as img and div in JavaScript relative to the browser window.

Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) In US hotels, what happens if you skip checkout and just leave the hotel? Every time I check out of a hotel, they ask me if my stay went fine, let me review my incidental charges and ask if they should charge the credit card used to check in.   But what if I simply walk out of the hotel without formally "checking out"? They have my credit card on file and these days you don't even have to return your room key if you want to keep a souvenir. Would it be rude and create more work for hotel employees?  The question arose after spending 15 minutes in the check out queue at a major US hotel.
