问题 I want to do something similar to the second answer here (but not quite similar): Simulate Ctrl-C keyboard interrupt in Python while working in Linux It's much simpler and I think I'm just missing something. Say, from a python script, I just want to call 'ping' and terminate it after the 10th time. I'm trying to do it like from the link above: p = subprocess.Popen(['ping', 'google.com'], stdout=subprocess.PIPE) for line in p.stdout: print line if re.search('10', line): break os.kill(p.pid,

问题 I am writing a script to automate setting up new projects for me. this includes pulling down a github repository. What I want to do is have some output from my script, then call git clone $repo I want to show the output from that command while it is running, but then when it has run if it has run successfully replace it's output (note just the git commands output, I still want the output from before that to be there) with repository successfully cloned and if failed just leave the output

for loops for regression over multiple variables & outputting a subset

I have tried to apply this QA: "efficient looping logistic regression in R" to my own problem but I cannot quite make it work. I haven't tried to use apply, but I was told by a few people that a for loop is the best here (if someone believes otherwise please feel free to explain!) I think this problem is pretty generalizeable and not too esoteric for the forum. This is what I want to achieve: I have a dataset with 3 predictor variables (gender, age, race) and a dependent variable (a proportion) for 86 genetic positions for several people. I want to run bivariate linear regressions for each

PHP cli script does not output anything

核能气质少年 提交于 2019-12-04 15:56:33
问题 So I have a php script which I execute using the following command: php -f my_script.php myArguments The script is under version control using svn. I just updated it, pasted the command to run it into a terminal, and executed it. However, there is no output. Not a failure message, not it printing anything, nothing. It looks like it never starts. Kind of like the following: me:/srv/scripts# php -f my_script.php myArguments me:/srv/scripts# Other scripts will run just fine. It is difficult for

GNU awk on win-7 cmd, won't redirect output to file

If relevant I have GNU awk V 3.1.6 downloaded directly from GNU pointed source in sourceforge. I am getting a page of URLs using wget for windows. After prcoessing the incoming file, I reduce it to single line, from which I have to extract a key value, which is quite a long string. The final line looks something like this: <ENUM_TAG>content"href:e@5nUtw3Fc^b=tZjqpszvja$sb=Lp4YGH=+J_XuupctY9zE9=&KNWbphdFnM3=x4*A@a=W4YXZKV3TMSseQx66AHz9MBwdxY@B#&57t3%s6ZyQz3!aktRNzcWeUm*8^$B6L&rs5X%H3C3UT&BhnhXgAXnKZ7f2Luy*jYjRLLwn$P29WzuVzKVnd3nVc2AKRFRPb79gQ$w$Nea6cA!A5dGRQ6q+L7QxzCM%XcVaap-ezduw?W@YSz!

Usage of FilterOutputStream

感情迁移 提交于 2019-12-04 12:22:32
What is practical usage of FilterOutputStream in Java? From javadocs: This class is the superclass of all classes that filter output streams. These streams sit on top of an already existing output stream (the underlying output stream) which it uses as its basic sink of data, but possibly transforming the data along the way or providing additional functionality. For me it seems to have same methods as OutputStream (maybe it overrides them for some reason?). What kind of data "transformation" does it offer and when can one use it in own Java application?

Download a file built in PHP output buffer from AJAX call

好久不见. 提交于 2019-12-04 12:18:40
问题 I am trying to build a CSV file in PHP, then call the PHP file from an AJAX call, which will then initiate a download of the CSV file upon success of the AJAX call. This works fine if I save a physical copy of the .csv on the server, but I would like to use php://ouput so I do not have to worry about physical files clogging up the server. Is it possible to initiate a download from returning php://output to AJAX? Here is my code: HTML/jquery: <!DOCTYPE html> <html lang="en"> <head> <meta

How to get the python Counter output ordered by order of inputs?

橙三吉。 提交于 2019-12-04 11:19:44
I have been working on getting the count(frequency) and then making the graph representation of it. I am using Counter class from collections using python. I want the output of the Counter in the order of the first come object. for example: offset=['a','b','c','a','b','b','b','c','c','c','c','c'] counts = Counter(offset) print counts output is: Counter({'c': 6, 'b': 4, 'a': 2}) As I want the output to be as follows, in the order of the first come object: Counter({'a': 2, 'b': 4, 'c': 6}) Is that possible? Thanks OrderedCounter by (2 lines long) multiple inheritance Following wonderful speech

Capture STDIN / STDERR / STDOUT of a process AFTER it's been started, using command line?

元气小坏坏 提交于 2019-12-04 11:18:17
问题 Thanks! My usercase: I started a lengthy interactive 'configure' process (say under 'screen'), and then realised I need to always answer 'no' until I see a particular keyword. Seems a waste of time to do this by hand (not to say that I can easily miss the keyword..) Thus it seems I want to pipe (a copy of) STDERR / STDOUT to a filter, and also be able to inject into the STDIN of a (console) process, AFTER it's been started, using command line? Is there a ready-made solution? The following
