I need to extract some values from a file in bash, on my CentOS system. In myfile.txt I have a list of objects called Info_region in which each object is identified with a code (eg. BARD1_region_005 or BIRC2_region_002 etc.) Moreover there are some others columns in which are reported some numerical variable. The same object (same code name) can be repeated several times in my file. I also have a file that contains a completed list with all object codes without duplicates. I would like to obtain an output.txt file in which each object (code name) is reported only once as in my list-file.txt and I would like to associate to this the maximum possible values associated with that code name in myfile.txt. myfile.txt: (columns are separated by tab) Info_region Lig_score   Lig_prevista    Lig_prevista_+1 Int_score   Expo_score  Protac_score BARD1_region_005    0   3   3   0   1   1 BARD1_region_006    0   1   1   0   1   1 BIRC2_region_001    1   6   7   0   1   2 BIRC2_region_001    1   7   8   0   1   2 BIRC2_region_001    0   2   2   0   0   0 BIRC2_region_001    0   12  12  0   1   1 BIRC2_region_001    1   10  11  -1  1   1 BIRC2_region_001    1   2   3   0   1   2 BIRC2_region_001    1   0   1   0   1   2 BIRC2_region_001    1   6   7   0   1   2 BIRC2_region_002    0   0   0   0   1   1 BIRC2_region_002    1   0   0   -1  0.5 0.5 BIRC2_region_003    0   0   0   0   1   1 BIRC2_region_004    0   1   1   0   1   1 UHRF1_region_004    0   0   0   1   1   2 UHRF1_region_004    0   0   0   1   1   2 UHRF1_region_004    1   0   1   0   0.5 1.5 UHRF1_region_004    0   0   0   1   1   2 UHRF1_region_005    0   3   3   1   1   2 UHRF1_region_005    1   0   0   -1  1   1  file-list.txt: Info_region BARD1_region_005 BARD1_region_006 BIRC2_region_001 BIRC2_region_002 BIRC2_region_003 BIRC2_region_004 UHRF1_region_004 UHRF1_region_005  output.txt: Info_region Lig_score   Lig_prevista    Lig_prevista_+1 Int_score   Expo_score  Protac_score BARD1_region_005    0   3   3   0   1   1 BARD1_region_006    0   1   1   0   1   1 BIRC2_region_001    1   12  12  0   1   2 BIRC2_region_002    1   0   0   0   1   1 BIRC2_region_003    0   0   0   0   1   1 BIRC2_region_004    0   1   1   0   1   1 UHRF1_region_004    1   0   1   1   1   2 UHRF1_region_005    1   3   3   1   1   2  Could someone help me please?

I have some data which looks like:  sampleA    ATGC    10   100 sampleA    ATGC    120  230 sampleA    ATGC    200  110   I want to print the min and max using the values in both column 3 and 4. So my output should look like:  sampleA   10  230   Thanks in advance
Do tag edits count for Archaeologist? Can you take Gorrilla Glue in Hold Luggage on a plane? What software can I use to write on PDFs? I'm used to OS X where the system PDF viewer will let you draw and write text on top of any PDF document. You can then flatten it and save as a new PDF. It saves paper and time so you can fill in any form without printing it and scanning it back to the computer.  It also lets you insert a scanned image of your signature.  Is there software for Ubuntu that would do that? Review-beta: Obviously good answer in low-quality Let the ring of fractions be denoted as $S^{-1}R$.       Proposition (from Robert Ash's textbook "Basic Abstract Algebra")      Define $f: R \rightarrow S^{-1}R$ by $f(a) = a/1$. Then f is a ring homomorphism. If S has no zero divisors then f is a monomorphism, and we say that R can be embedded in $S^{-1}R$. In particular:      (i) A commutative ring R cna be embedded in its complete (or *full) ring of fractions ($S^{-1}R$, where S consists of all non-divisors of zero in R).       (ii) An integral domain can be embedded in its quotient field.    Why does the proposition say "If S has no zero divisors..."? If S really had zero divisors, then this wouldn't even be properly defined, right? Because we would have a/0 for some a in R. An equality involving the mean value property I am trying to establish that  $$\frac2{\pi}\int_0^{2\pi} f(e^{i\theta})\cos^2\left(\frac{\theta}{2}\right)\;\mathrm d\theta=2f(0)+f^\prime(0)$$  for $f$ analytic on $|z| &lt; R,\; R &gt; 1$  I think I am making a mistake somewhere, please point it out to me.Here's what I've done unsing the mean value property and Cauchy's integral formula:  $$2f(0)+f&#39;(0)=2(\frac1{2\pi}\int_0^{2\pi} f(e^{i\theta})d\theta + \frac1{2\pi i}\int_0^{2\pi}\frac{f(e^{i\theta})ie^{i\theta}}{e^{i2\theta}}=\frac{1}{\pi}\int_0^{2\pi} f(e^{i\theta})d\theta\frac1{2\pi}\int_0^{2\pi}\frac{f(e^{i\theta})}{e^{i\theta}}\quad\text{(1)}$$  But when I develop the expression $\frac2{\pi}\int_0^{2\pi} f(e^{i\theta})\cos^2(\frac{\theta}{2}) d\theta$ I get:  $$\frac1{\pi}\int_0^{2\pi} f(e^{i\theta})d\theta+\frac1{2\pi}\int_0^{2\pi}f(e^{i\theta})[{e^{i\theta}}+e^{i-\theta}]d\theta \quad\text{(2)}$$  The second integral in (1) differs from the second integral in (2). Thanks. Skip certain tables with mysqldump Show hidden files on Mac OS X Mojave using Terminal To see my /etc folder I've tried this command in Terminal:  sudo chflags nohidden /etc   followed by:  sudo defaults write com.apple.Finder AppleShowAllFiles true; killall Finder   also tried:  sudo defaults write com.apple.Finder AppleShowAllFiles YES; killall Finder   Neither of them seemed to work. How to clear the interpreter console? Is there a built-in checksum/hash utility on Windows 7? In my native language, we can say:     I have dog   Because I don't want to say a dog (one dog, how many dogs) or the dog (that dog, the listener don't care which dog).  p.s. after 3 years later, I have to say, why I ask this question, is I still cannot grasp how to use the right 'article word'. sometimes, a noun will use an article, sometimes, a noun could not(or omit) the article word before it. there aren't a formula for this. So, I have to remember all the time! I feel so frustrate I was granted a visa to Australia few months ago. I’d like to travel to Australia in few days. However, I’ve just renewed my passport and I don’t have enough time to inform them about my passport renewal. Can I travel to Australia by carrying both my old and my new passports? How to revert to GNOME Classic Desktop? Let $a,b,c$ real numbers. Prove the inequality $|a-b| \leq |a-c| + |c-b|$. Prove that equality holds if and only if $a \leq c \leq b$ or $b \leq c \leq a$.   I've tried starting with just $a \leq c$ and using field properties to reconstruct the inequality, however I haven't been able to make it work. I also tried making the negatives positive and stripping the inequalities and making something happen but again I don't know if that's a proper rule and it didn't seem to get me anywhere.

How to set programmatically multiple arguments for views contextual filters How to set programmatically multiple arguments for views contextual filters?  I can do it with one argument, it works great, but not with multiple arguments.  I want to select all nodes created by a list of people, but views only takes first in array into consideration:  $array = array(3250,32); $view = views_get_view('myview'); $view-&gt;set_display("myblock"); $view-&gt;set_arguments($array); $view-&gt;pre_execute(); $view-&gt;execute(); $content = $view-&gt;render();    Am I doing something wrong?

There is an experimental timeline view for questions now available on meta ONLY! (Now working on SO, SF, and SU as well)  This is partially motivated by comments about how difficult it is to follow very active questions which have a lot of activity, and also the feedback on the API which was heavily dominated by "we need to know what happened in this time range" type responses.  It can only be accessed through URL hackery at the moment. To get to it, enter question URLs like so:  https://meta.stackexchange.com/posts/{id}/timeline  This is a chronological timeline of everything that happened on a question, including   initial question ask answers  revisions comments closure, deletion, reopen, undelete, etc votes   all based on when they happened in chronological order.  We are thinking about making this a fourth tab on the question, like so:  Timeline | Oldest | Newest | Votes  Please try it out and provide feedback. It is still a little rough, so we are not looking for highly detailed bug reports, just more general feedback.  Timeline view for this question:
