extract

I have a file and it's content is a list of some URLs, I want to extract the domain names from this list of URLs in bash Example: sub1.domain.com domain3.com sub5.domain.ext subof.subdomain.domainx.ex2 I want to extract just domain names from this list How can I do this? Thank you You can use grep : grep -Eo '[^.]+\.[^.]+$' file.txt Example: $ cat file.txt sub1.domain.com sub2.domains2.com domain3.com sub5.domain.ext subof.subdomain.domainx.ex2 $ grep -Eo '[^.]+\.[^.]+$' file.txt domain.com domains2.com domain3.com domain.ext domainx.ex2 Note that this will return co.uk for www.google.co.uk .

I am working with installers at the moment, and the first thing I thought of was to put a .zip file on a server and then having it download that and extract. However, I've seen installers run without an internet connection (which wouldn't work for mine), and they say "extracting files", not downloading. Is there some way to store files in an installer, and is there anything wrong with me having an installer like I currently do? The overview of a Windows Installer setup is that files are typically in a CAB file as an embedded resource, and the rest of the setup is a database that contains info

I am trying to extract data from a webpage to insert it to a database. The data I'm interested in is in the div's which have a class="company". On one webpage there are 15 or less div's like that, and there are many pages I am trying to extract this data from. For this reason I am trying to find a automatic solution for data extraction. The div with a class="company" is as follows (there are 15 or less divs like this on one page with different data): <div class="company" id="company-6666"> <!-- EXTRACT 'company-6666' from id="company-6666" --> <div class="top clearfix"> <div class="name

I have quite long config file and I need to extract specific strings from the file. What I want to extract/read is InstallDir for specific number position e.g. for 20540. I know how to find string in INI or XML, but cannot handle this form of file. Piece of the file that shows structure: "212280" { "InstallDir" "D:\\XYZ\\stu\\opr" "UpdateKBtoDL" "0" "HasAllLocalContent" "1" "UpToDate" "1" "DisableAutoUpdate" "0" } "20540" { "UpdateKBtoDL" "0" "InstallDir" "C:\\ABC\\def\\ghi" "HasAllLocalContent" "1" "UpToDate" "1" "maintenance_time" "1339663134" "DisableAutoUpdate" "0" } "4560" { "UpdateKBtoDL

I have checked out many pages but most of the tutorials and script return an error code with this type of JSON output. So how would I be able to extract the data from this JSON in Java?: [ { "user":{"id":"1","username":"user1"}, "item_name":"item1", "custom_field":"custom1" }, { "user":{"id":"2","username":"user2"}, "item_name":"item2", "custom_field":"custom2" }, { "user":{"id":"3","username":"user3"}, "item_name":"item3", "custom_field":"custom3" } ] If you want to use Gson, then first you declare classes for holding each element and sub elements: public class MyUser { public String id;

I'm trying to extract .zip files and I'm using this code: String zipFile = Path + FileName; FileInputStream fin = new FileInputStream(zipFile); ZipInputStream zin = new ZipInputStream(fin); ZipEntry ze = null; while ((ze = zin.getNextEntry()) != null) { UnzipCounter++; if (ze.isDirectory()) { dirChecker(ze.getName()); } else { FileOutputStream fout = new FileOutputStream(Path + ze.getName()); while ((Unziplength = zin.read(Unzipbuffer)) > 0) { fout.write(Unzipbuffer, 0, Unziplength); } zin.closeEntry(); fout.close(); } } zin.close(); but the problem is that, while debugging, when the code

As the title implies, how does one extract the sub- and superdiagonal of a matrix? Using diag . For the superdiagonal, you just discard the last row and first column. For the subdiagonal, discard first row, last column: m <- matrix(1:9,nrow=3) > m [,1] [,2] [,3] [1,] 1 4 7 [2,] 2 5 8 [3,] 3 6 9 > diag(m) [1] 1 5 9 > diag(m[-nrow(m),-1]) [1] 4 8 > diag(m[-1,-ncol(m)]) [1] 2 6 You may need to reshape the results.... help(lower.tri) help(upper.tri) help(diag) upper.tri and lower.tri do not include the diagonals. 来源： https://stackoverflow.com/questions/9885067/extract-sub-and-superdiagonal-of-a
